Cozy Banana Baked Oats That Taste Like Banana Bread
These banana baked oats turn a few overripe bananas and some rolled oats into a warm, spoonable breakfast that tastes like banana bread in casserole form.

It comes together in one bowl, then slides into the oven while you get ready. The top gets just a little crusty and the inside stays soft and custardy.
What Makes These Oats So Good
The bananas do all the heavy lifting, sweetening and making the whole bake tender without a pile of extra sugar. It feels like a treat but uses mostly pantry staples.
The texture lands somewhere between a soft baked oatmeal and bread pudding. Clean slices that hold together but still have that creamy spoon feel.
Ingredients

- 2 large ripe bananas: the spottier the better for natural sweetness
- 2 cups rolled oats: old-fashioned oats, not quick oats
- 2 cups milk: any variety (dairy, almond, oat) works
- 2 large eggs
- 2 tbsp melted butter or coconut oil (optional): adds richness and a tender crumb
- 1 tsp baking powder
- 1 tsp ground cinnamon
- 1 tsp vanilla extract
- 1 pinch sea salt
- 2 tbsp maple syrup (optional): only if your bananas need a little extra sweetness
Variations / Substitutions
- Add fruit: Fold a handful of blueberries or chopped apple into the batter before baking.
- Gluten free: Use certified gluten-free rolled oats.
- Make it nutty: Stir in 1/4 cup chopped walnuts or pecans for crunch.
- Chocolate: A few dark chocolate chips scattered in turn this more into a dessert-like oatmeal.
- Dairy free: Use non-dairy milk and swap the butter for coconut oil or omit it entirely.
If you love pumpkin baking season, my pumpkin baked oats use a can of puree the same way.
How to Make Banana Baked Oats
Step 1: Mash the Bananas and Mix the Wet Ingredients

Mash the 2 bananas in a large bowl with a fork until mostly smooth, a few small lumps are fine. Whisk in the 2 eggs, 2 cups milk, 2 tbsp melted butter, and 1 tsp vanilla until combined.
The mixture will look thin and milky at this point. That gives the oats enough liquid to absorb as they bake.
Step 2: Fold in the Oats and Spices

Stir in the 2 cups oats, 1 tsp baking powder, 1 tsp cinnamon, and the pinch of salt. Use a spatula to scrape the bottom of the bowl so no dry pockets of powder hide down there.
The batter stays quite runny, which is exactly what you want. The oats will soak it all up in the oven.
Step 3: Bake Until Golden and Set

Preheat your oven to 350°F (175°C). Pour the mixture into a greased 8-inch (20 cm) square baking dish. Bake for 35 to 40 minutes, until the center is just set and the edges start to pull away from the pan.
The top will be puffed and golden, and the whole kitchen will smell like warm banana bread.
Step 4: Slice and Serve the Oats

Let the baked oats cool in the pan for at least 10 minutes. This little rest gives them time to firm up so they slice into clean squares.
Serve warm, scooped into bowls, with a splash of cold milk, a spoonful of yogurt, or a drizzle of honey.
A Few Tips Before You Start
- Really ripe bananas with lots of spots deliver the best natural sweetness. If yours are more yellow than spotted, add the optional maple syrup to the wet mix.
- For a crispier top, sprinkle a tablespoon of raw or brown sugar over the batter right before it hits the oven.
- Leftovers cut most cleanly when the bake has cooled completely. Pop a slice in the microwave for 30 seconds to bring back the soft texture.
- Stir a handful of fresh blueberries or chocolate chips into the batter if you want to switch it up without changing the core recipe.
Bake times by pan size:
| Pan Size | Material | Bake Time |
|---|---|---|
| 8-inch square | Metal | 35-40 mins |
| 9-inch square | Metal | 30-35 mins |
| 8-inch square | Glass | 40-45 mins* |
*For glass, reduce oven temperature by 25°F to avoid over-browning the bottom.
Keeping Leftover Baked Oats Fresh
- Refrigerate: Store slices in an airtight container for up to 4 days.
- Reheat: A quick 30 to 60 seconds in the microwave warms them through without drying out.
- Serve cold: You can eat it straight from the fridge, but it will be a little more firm than when warm.
What to Serve with Banana Baked Oats
A thick dollop of Greek yogurt balances the soft, sweet oats with tang and creaminess. Fresh berries or sliced peaches add a bright pop against the warm cinnamon notes. A drizzle of peanut or almond butter melts into the nooks and makes the whole bowl feel more substantial.
Frequently Asked Questions
Can I use quick oats instead of rolled oats?
Yes, but the texture will be softer and a bit more porridge-like. It still works in a pinch.
How do I know when the bake is done?
The center should be just set and not jiggly when you gently shake the pan. A toothpick inserted in the middle will come out mostly clean with a few moist crumbs.
Can I make this vegan?
Replace the eggs with 2 flax eggs (2 tbsp ground flaxseed mixed with 5 tbsp water, let sit 5 minutes) and use a non-dairy milk and oil or no butter.
Can I use frozen bananas?
Yes, thaw them first and drain off any excess liquid before mashing so the batter doesn’t get watery.
