12 Baked Apple Oatmeal Recipes Worth Turning the Oven On For

Baked apple oatmeal works because the apples release just enough juice to soften the oats while the milk and eggs set into a tender custard around them. Cinnamon, brown sugar, and a hot oven give it a golden top and a warm, spoonable centre. The versions below take that same foundation in genuinely different directions, from a classic pan to spiced, fruity, and freezer-ready variations.

Start with Classic Cinnamon Baked Apple Oatmeal for the benchmark you will judge everything else against. Try Peanut Butter Baked Apple Oatmeal if you want it richer, Cranberry Orange Baked Apple Oatmeal if you want it brighter, and Make-Ahead Freezer Apple Oatmeal Bake if you are planning meals.

Which Baked Apple Oatmeal Should You Make?

Classic Cinnamon Baked Apple Oatmeal

This is the benchmark version I keep going back to when the apples are crisp and the morning is cold. You get a soft custard around the oats, tender apple pieces, and just enough cinnamon to carry everything.

Ingredients (makes 6 servings)

• Old-fashioned rolled oats: 180 g (2 cups)
• Milk, any fat: 480 ml (2 cups)
• Large eggs: 2
• Unsalted butter, melted: 60 g (4 tbsp)
• Brown sugar: 100 g (1/2 cup)
• Baking powder: 1 tsp
• Ground cinnamon: 2 tsp
• Kosher salt: 1/2 tsp
• Medium apples, cored and chopped: 2, about 300 g (2 cups)
• Butter, for the dish: 1 tsp

Instructions

Step 1: Heat your oven to 180C (350F) and rub 1 tsp butter around a 20 cm (8 inch) square baking dish. You want the sides coated so the edges don’t stick.

Step 2: Whisk 480 ml (2 cups) milk, 2 eggs, 60 g (4 tbsp) melted butter, 100 g (1/2 cup) brown sugar, 2 tsp cinnamon, 1 tsp baking powder, and 1/2 tsp salt in a large bowl until the sugar starts to dissolve. You’ll see the mixture go from grainy to smooth.

Step 3: Stir in 180 g (2 cups) oats and the 2 chopped apples. Fold the mixture a few times so every oat is wet, and you can see the apples spread evenly through the bowl.

Step 4: Pour the oat mixture into your prepared dish and smooth the top with a spatula. Bake for 40 to 45 minutes, until the centre is set and the top turns deep golden. You can jiggle the dish; the middle should barely move.

Step 5: Let the oatmeal sit for 10 minutes, then you can scoop it into warm bowls. Serve with a splash of cold milk or a spoon of yogurt, whichever you have nearby.

Maple Walnut Baked Apple Oatmeal

You get a deeper sweetness here from maple syrup and a toasted nut crunch that stands up to the soft apples. I like this one for weekends when a bowl of oatmeal should feel a little more special.

Ingredients (makes 8 servings)

• Old-fashioned rolled oats: 270 g (3 cups)
• Milk: 600 ml (2 1/2 cups)
• Large eggs: 3
• Maple syrup: 120 ml (1/2 cup)
• Unsalted butter, melted: 45 g (3 tbsp)
• Baking powder: 1 1/2 tsp
• Ground cinnamon: 2 tsp
• Medium apples, cored and chopped: 3, about 450 g (3 cups)
• Walnut pieces: 60 g (1/2 cup)
• Soft butter, for the dish: 1 tsp

Instructions

Step 1: Heat your oven to 180C (350F). Rub 1 tsp soft butter inside a 23 x 33 cm (9 x 13 inch) baking pan, then set your pan aside.

Step 2: Whisk 600 ml (2 1/2 cups) milk, 3 eggs, 120 ml (1/2 cup) maple syrup, and 45 g (3 tbsp) melted butter in a large bowl until the syrup stops sitting at the bottom. You’ll notice the mixture turn a pale caramel colour.

Step 3: Add 270 g (3 cups) oats, 1 1/2 tsp baking powder, 2 tsp cinnamon, the 3 chopped apples, and 60 g (1/2 cup) walnuts to the bowl. Stir everything together until you no longer see dry oats hiding under the apples.

Step 4: Pour the mixture into your prepared pan and spread it evenly with the back of your spoon. Bake for 40 to 45 minutes, until the edges pull away from the pan and the top has a firm golden crust. You can test the centre with a knife; it should come out clean.

Step 5: Let the baked oatmeal sit for 15 minutes so it slices cleanly. Cut it into 8 squares and serve warm, with extra maple syrup on the side if you like.

Apple Crisp Baked Oatmeal with Oat Streusel

This one gives you the soft baked oatmeal base and a separate crisp oat streusel on top, so every spoonful has a crackly finish. You’ll want it when you’re serving people who think oatmeal is boring.

Ingredients (makes 9 servings)

• Old-fashioned rolled oats, divided: 315 g (3 1/2 cups)
• Milk: 720 ml (3 cups)
• Large eggs: 4
• Brown sugar: 150 g (3/4 cup)
• Unsalted butter, melted and divided: 90 g (6 tbsp)
• Ground cinnamon: 1 tbsp
• Baking powder: 2 tsp
• Medium apples, cored and chopped: 4, about 600 g (4 cups)
• Soft butter, for the dish: 1 tsp

Instructions

Step 1: Heat your oven to 180C (350F). Coat a 23 x 33 cm (9 x 13 inch) baking pan with 1 tsp soft butter and set your pan aside.

Step 2: Whisk 720 ml (3 cups) milk, 4 eggs, 100 g (1/2 cup) of the brown sugar, 45 g (3 tbsp) of the melted butter, 1 tbsp cinnamon, and 2 tsp baking powder in a large bowl. You want the sugar to dissolve so the base bakes evenly.

Step 3: Stir 270 g (3 cups) of the oats and the 4 chopped apples into the wet mixture. Fold gently until all the oats have been coated, and you can see apple chunks spread through the bowl.

Step 4: Work the remaining 45 g (1/2 cup) oats, remaining 50 g (1/4 cup) brown sugar, and remaining 45 g (3 tbsp) melted butter together with your fingers until it forms small clumps. You are looking for a rubble that holds together when you pinch it.

Step 5: Pour the oat mixture into your prepared pan and scatter the streusel clumps over the top in an even layer. Bake for 45 to 50 minutes, until the top is deeply browned and the centre no longer wobbles when you shake the pan gently.

Step 6: Let it cool for 20 minutes, then you can cut it into 9 squares. Serve each square with a dollop of cold yogurt or a drizzle of warm honey.

Peanut Butter Baked Apple Oatmeal

Peanut butter melts into the custard and turns this into something closer to a warm, spoonable snack cake. I use smooth peanut butter because it disappears into the oats without clumping.

Ingredients (makes 4 servings)

• Old-fashioned rolled oats: 180 g (2 cups)
• Milk: 480 ml (2 cups)
• Large eggs: 2
• Smooth peanut butter: 120 g (1/2 cup)
• Brown sugar: 50 g (1/4 cup)
• Baking powder: 1 tsp
• Ground cinnamon: 1 tsp
• Kosher salt: 1/4 tsp
• Medium apples, cored and chopped: 2, about 300 g (2 cups)
• Soft butter, for the dish: 1 tsp

Instructions

Step 1: Heat your oven to 180C (350F) and grease a 20 cm (8 inch) square baking dish with 1 tsp soft butter. You’ll want the dish fully coated because the peanut butter likes to stick.

Step 2: Whisk 480 ml (2 cups) milk, 2 eggs, 120 g (1/2 cup) peanut butter, 50 g (1/4 cup) brown sugar, 1 tsp cinnamon, 1 tsp baking powder, and 1/4 tsp salt in a medium bowl. Keep whisking until you see the peanut butter break down and the mixture goes smooth, about 1 minute.

Step 3: Add 180 g (2 cups) oats and the 2 chopped apples. Stir everything with a wooden spoon until you no longer see dry oats, then scrape the bottom of the bowl once.

Step 4: Pour the mixture into your greased dish and level the top. Bake for 35 to 40 minutes, until the edges are set and the centre has puffed slightly. You’ll smell the peanut butter toasting before the timer goes off.

Step 5: Let the dish cool for 10 minutes, then you can scoop or slice it into 4 portions. Serve warm with sliced banana or a drizzle of honey if you want it sweeter.

Caramel Apple Baked Oatmeal

You get the flavour of caramel apples from blitzed dates and warm cinnamon, without a candy thermometer in sight. This is the one to make when you want dessert for breakfast but still want oats in the bowl.

Ingredients (makes 4 servings)

• Old-fashioned rolled oats: 180 g (2 cups)
• Milk: 480 ml (2 cups)
• Large eggs: 2
• Medjool dates, pitted: 150 g (1 cup)
• Unsalted butter, melted: 60 g (4 tbsp)
• Ground cinnamon: 1 1/2 tsp
• Baking powder: 1 tsp
• Medium apples, cored and chopped: 2, about 300 g (2 cups)
• Soft butter, for the dish: 1 tsp

Instructions

Step 1: Heat your oven to 180C (350F) and rub 1 tsp soft butter inside a 20 cm (8 inch) square baking dish. You’ll use this dish later.

Step 2: Put 480 ml (2 cups) milk, 150 g (1 cup) pitted dates, 60 g (4 tbsp) melted butter, and 1 1/2 tsp cinnamon in a blender. Blend on high for 30 seconds until you have a smooth, caramel-coloured liquid.

Step 3: Whisk the 2 eggs in a large bowl until the yolks and whites are combined. Pour in the date mixture and 1 tsp baking powder, then whisk again until you see no streaks.

Step 4: Add 180 g (2 cups) oats and the 2 chopped apples to the bowl. Stir with a spatula until the apples are coated and you can see the date mixture has reached every spoonful.

Step 5: Pour everything into your prepared dish and smooth the top. Bake for 35 to 40 minutes, until the centre is just set and the edges start to caramelise. You’ll smell a toasty sweetness near the end.

Step 6: Let the dish cool for 10 minutes before you cut it into 4 servings. Serve warm, with a little extra date syrup or warm milk poured over the top.

Spiced Chai Apple Oatmeal

This version brings cardamom, ginger, and black tea into the milk so the whole bake tastes like chai from the inside out. I like it on cooler mornings when cinnamon alone won’t cut it.

Ingredients (makes 6 servings)

• Old-fashioned rolled oats: 180 g (2 cups)
• Whole milk: 480 ml (2 cups)
• Black tea bags: 2
• Large eggs: 2
• Brown sugar: 80 g (1/3 cup plus 1 tbsp)
• Unsalted butter, melted: 45 g (3 tbsp)
• Chai spice blend: 1 1/2 tsp
• Baking powder: 1 tsp
• Medium apples, cored and chopped: 2, about 300 g (2 cups)
• Soft butter, for the dish: 1 tsp

Instructions

Step 1: Heat your oven to 180C (350F) and rub 1 tsp soft butter over the inside of a 20 cm (8 inch) square baking dish. You’ll want the corners covered.

Step 2: Warm 480 ml (2 cups) whole milk in a small saucepan over medium heat until it steams, about 4 minutes. Turn off the heat, add the 2 black tea bags, and leave them to steep for 5 minutes. You’ll see the milk turn a light tan.

Step 3: Remove the tea bags and squeeze them gently with a spoon. Whisk the warm tea milk, 2 eggs, 80 g (1/3 cup plus 1 tbsp) brown sugar, 45 g (3 tbsp) melted butter, 1 1/2 tsp chai spice blend, and 1 tsp baking powder in a large bowl until smooth. You want the sugar dissolved before the oats go in.

Step 4: Stir in 180 g (2 cups) oats and the 2 chopped apples until everything is evenly mixed. Scrape the bottom of the bowl once so you don’t miss any dry patches.

Step 5: Pour the mixture into your prepared dish and level the top with a spoon. Bake for 35 to 40 minutes, until the top is puffed and a knife inserted in the centre comes out clean. You’ll smell the cardamom and ginger the moment you open the oven.

Step 6: Let it cool for 10 minutes, then you can cut it into 6 servings and serve warm with honey or a spoon of yogurt.

Cranberry Orange Baked Apple Oatmeal

Cranberries and fresh orange juice give this bake a sharp, bright edge that cuts through the soft oats. You’ll want it in the middle of winter when you need something a little more lively on the breakfast table.

Ingredients (makes 8 servings)

• Old-fashioned rolled oats: 270 g (3 cups)
• Milk: 480 ml (2 cups)
• Fresh orange juice: 180 ml (3/4 cup)
• Large eggs: 3
• Brown sugar: 100 g (1/2 cup)
• Unsalted butter, melted: 60 g (4 tbsp)
• Baking powder: 1 1/2 tsp
• Fresh cranberries, halved: 150 g (1 1/2 cups)
• Medium apples, cored and chopped: 3, about 450 g (3 cups)
• Soft butter, for the dish: 1 tsp

Instructions

Step 1: Heat your oven to 180C (350F) and grease a 23 x 33 cm (9 x 13 inch) baking dish with 1 tsp soft butter. You’ll want the corners coated.

Step 2: Whisk 480 ml (2 cups) milk, 180 ml (3/4 cup) orange juice, 3 eggs, 100 g (1/2 cup) brown sugar, 60 g (4 tbsp) melted butter, and 1 1/2 tsp baking powder in a large bowl until smooth. You may see the milk thicken slightly from the orange juice, which is fine.

Step 3: Stir 270 g (3 cups) oats, 150 g (1 1/2 cups) halved cranberries, and the 3 chopped apples into the wet mixture. Fold everything together until you see the cranberries speckled evenly and no dry oats remain.

Step 4: Pour the mixture into your greased dish and level the surface with the back of a spoon. Bake for 40 to 45 minutes, until the top is lightly golden and the centre is set. You can pierce the middle with a knife to check; it should come out clean.

Step 5: Let it cool for 15 minutes, then you can slice it into 8 servings. Serve warm with orange slices or a drizzle of cold cream, whichever you have.

High-Protein Greek Yogurt Apple Oatmeal

Greek yogurt gives this version a tangy, custard-like centre and enough protein to keep you full past mid-morning. I use whole milk yogurt, but any plain Greek yogurt you have works.

Ingredients (makes 4 servings)

• Old-fashioned rolled oats: 180 g (2 cups)
• Plain Greek yogurt: 245 g (1 cup)
• Milk: 240 ml (1 cup)
• Large eggs: 3
• Honey: 60 ml (1/4 cup)
• Unsalted butter, melted: 30 g (2 tbsp)
• Ground cinnamon: 1 1/2 tsp
• Baking powder: 1 tsp
• Medium apples, cored and chopped: 2, about 300 g (2 cups)
• Soft butter, for the dish: 1 tsp

Instructions

Step 1: Heat your oven to 180C (350F) and coat a 20 cm (8 inch) square baking dish with 1 tsp soft butter. You’ll need that butter later to release the edges.

Step 2: Whisk 245 g (1 cup) Greek yogurt, 240 ml (1 cup) milk, 3 eggs, 60 ml (1/4 cup) honey, 30 g (2 tbsp) melted butter, 1 1/2 tsp cinnamon, and 1 tsp baking powder in a large bowl. Keep going until you see a smooth, pale yellow mixture with no yogurt lumps.

Step 3: Add 180 g (2 cups) oats and the 2 chopped apples to the bowl. Stir with a spatula until the apples are coated and you can no longer see dry oats at the bottom.

Step 4: Scrape the mixture into your prepared dish and smooth the top into an even layer. Bake for 35 to 40 minutes, until the centre puffs up and the edges turn golden. You’ll find a knife inserted into the middle should come out clean.

Step 5: Let the dish cool for 10 minutes, then you can cut it into 4 pieces. Serve with a spoon of yogurt and a little honey if you want it creamier.

Vegan Baked Apple Oatmeal

No eggs or dairy here, just ground flaxseed doing the binding work and oat milk carrying the custard. This is the one I point to when someone at the table does not eat animal products but still wants a warm, spiced breakfast.

Ingredients (makes 8 servings)

• Old-fashioned rolled oats: 270 g (3 cups)
• Oat milk: 600 ml (2 1/2 cups)
• Ground flaxseed: 2 tbsp
• Water: 5 tbsp
• Maple syrup: 120 ml (1/2 cup)
• Coconut oil, melted: 45 g (3 tbsp)
• Ground cinnamon: 2 tsp
• Baking powder: 1 1/2 tsp
• Medium apples, cored and chopped: 3, about 450 g (3 cups)
• Soft coconut oil, for the dish: 1 tsp

Instructions

Step 1: Heat your oven to 180C (350F) and grease a 23 x 33 cm (9 x 13 inch) baking dish with 1 tsp coconut oil. You’ll want to coat the corners well.

Step 2: Stir 2 tbsp ground flaxseed with 5 tbsp water in a small bowl and set it aside for 5 minutes. You’ll see it thicken into a gel that holds the bake together.

Step 3: Whisk 600 ml (2 1/2 cups) oat milk, 120 ml (1/2 cup) maple syrup, 45 g (3 tbsp) melted coconut oil, 2 tsp cinnamon, and 1 1/2 tsp baking powder in a large bowl until smooth. Add the flax mixture and whisk again, so you know it is distributed evenly.

Step 4: Fold 270 g (3 cups) oats and the 3 chopped apples into the wet ingredients. Stir from the bottom of the bowl, and you should see every oat coated and glossy.

Step 5: Pour the mixture into your greased dish and spread it out evenly. Bake for 40 to 45 minutes, until the top is deep golden and the centre no longer jiggles when you shake the pan.

Step 6: Let it cool for 15 minutes before you cut it into 8 pieces. Serve warm with extra oat milk or a spoon of apple butter.

Gluten-Free Apple Oatmeal Bars

These bars hold their shape for packed lunches and bake with almond flour so the bottom gets a little more structure. I chop the apples smaller here so every square has fruit but still slices cleanly.

Ingredients (makes 16 bars)

• Certified gluten-free rolled oats: 270 g (3 cups)
• Almond flour: 60 g (1/2 cup)
• Milk: 480 ml (2 cups)
• Large eggs: 3
• Maple syrup: 120 ml (1/2 cup)
• Unsalted butter, melted: 60 g (4 tbsp)
• Ground cinnamon: 2 tsp
• Baking powder: 1 1/2 tsp
• Medium apples, cored and finely chopped: 3, about 450 g (3 cups)
• Soft butter, for the dish: 1 tsp

Instructions

Step 1: Heat your oven to 180C (350F) and line a 23 x 33 cm (9 x 13 inch) baking pan with parchment paper, leaving a little overhang on two sides. You’ll thank yourself when it’s time to lift the bars out.

Step 2: Whisk 480 ml (2 cups) milk, 3 eggs, 120 ml (1/2 cup) maple syrup, and 60 g (4 tbsp) melted butter in a large bowl until smooth. You should see the maple syrup fully blended into the milk.

Step 3: Add 270 g (3 cups) certified gluten-free oats, 60 g (1/2 cup) almond flour, 2 tsp cinnamon, and 1 1/2 tsp baking powder. Stir until the dry ingredients disappear, then you can fold in the 3 finely chopped apples.

Step 4: Scrape the mixture into your lined pan and press it into an even layer with a spatula. Bake for 35 to 40 minutes, until the edges are browned and the centre feels firm when you press it lightly.

Step 5: Lift the whole slab out by the parchment and set it on a rack to cool for 30 minutes. Cut it into 16 bars and you can serve them warm or at room temperature.

Air Fryer Apple Oatmeal Cups

These little cups bake in about half the time of a full dish and give you grab-and-go portions. I like them for busy mornings when a big pan is too much.

Ingredients (makes 12 cups)

• Old-fashioned rolled oats: 120 g (1 1/3 cups)
• Milk: 240 ml (1 cup)
• Large egg: 1
• Brown sugar: 50 g (1/4 cup)
• Unsalted butter, melted: 30 g (2 tbsp)
• Ground cinnamon: 1 tsp
• Baking powder: 1/2 tsp
• Medium apple, cored and finely diced: 1, about 150 g (1 cup)
• Soft butter, for the molds: 1 tsp

Instructions

Step 1: Grease 12 silicone muffin cups with 1 tsp soft butter and set them in your air fryer basket. You can also use a small 12-cup silicone tray that fits your basket.

Step 2: Whisk 1 egg, 240 ml (1 cup) milk, 50 g (1/4 cup) brown sugar, 30 g (2 tbsp) melted butter, 1 tsp cinnamon, and 1/2 tsp baking powder in a medium bowl until frothy. You’ll see a few bubbles on the surface, which means the baking powder is active.

Step 3: Stir 120 g (1 1/3 cups) oats and the 1 finely diced apple into the wet mixture. Keep folding until you can pick up a spoonful and see no dry oats clinging to the bottom.

Step 4: Divide the mixture evenly among the greased cups, filling each about three-quarters full so you leave room for the cups to puff.

Step 5: Air fry at 160C (320F) for 14 to 18 minutes, until the tops are golden and a toothpick comes out clean from the middle. Let them cool for 5 minutes, then you can turn the cups out and serve warm.

Make-Ahead Freezer Apple Oatmeal Bake

This one lets you do the measuring and chopping once, then wake up to a breakfast that only needs the oven. You’ll make two freezer bags, so the second one is ready for the next icy morning.

Ingredients (makes 2 freezer bags, 4 servings each)

• Old-fashioned rolled oats: 360 g (4 cups)
• Milk: 960 ml (4 cups)
• Large eggs: 4
• Brown sugar: 150 g (3/4 cup)
• Unsalted butter, melted: 90 g (6 tbsp)
• Ground cinnamon: 1 tbsp
• Baking powder: 2 tsp
• Kosher salt: 1/2 tsp
• Medium apples, cored and chopped: 4, about 600 g (4 cups)
• Soft butter, for the dishes: 2 tsp

Instructions

Step 1: Whisk 960 ml (4 cups) milk, 4 eggs, 150 g (3/4 cup) brown sugar, 90 g (6 tbsp) melted butter, 1 tbsp cinnamon, 2 tsp baking powder, and 1/2 tsp salt in a very large bowl until the sugar has dissolved. You’ll see the mixture turn a uniform tan.

Step 2: Stir in 360 g (4 cups) oats and the 4 chopped apples. Fold everything until you can scoop from the bottom and find no dry oats, then divide the mixture between two large labelled freezer bags.

Step 3: Press each bag flat, seal it with as little air as you can, and lay the bags in the freezer. Freeze for up to 3 months, and remember to thaw one bag in the fridge overnight before you want to bake it.

Step 4: On baking day, heat your oven to 180C (350F). Rub 1 tsp soft butter inside a 20 cm (8 inch) square baking dish and pour the thawed mixture into it, spreading it smooth.

Step 5: Bake for 40 to 45 minutes, until the top is deep golden and the centre no longer wobbles when you shake the dish. You can cover the top with foil after 30 minutes if it browns too fast.

Step 6: Let it cool for 10 minutes, then you can scoop it into 4 warm bowls. Serve with a drizzle of milk or a spoon of apple butter, and you have the second bag waiting for another morning.

The most important step across all these recipes is the resting time. Let the baked oatmeal sit for 10 to 15 minutes after it comes out of the oven, so the custard sets and you get clean slices instead of a loose spoonful.

Pick the version that matches your morning and get it in the oven. You have plenty of good reasons, and they all start with apples.
