Ingredients You’ll Need
Regular rolled oats: You’ll need ½ cup of these hearty oats. They create the most amazing crunchy topping that makes this crumble so special!
Whole-wheat pastry flour: Just 2 tablespoons helps bind everything together. If you don’t have pastry flour, regular whole wheat flour works great too.
Brown sugar: You’ll use 3 tablespoons total – 2 for the topping and 1 for the apples. That lovely molasses flavor makes everything taste so much richer.
Ground cinnamon: Half a teaspoon brings all those warm, cozy flavors together. It’s like a hug in spice form!
Cold butter: One tablespoon cut into small pieces creates those perfect crumbly bits we all love. Make sure it stays cold for the best texture.
Golden Delicious apples: Three medium apples, cored and cut into thin wedges. These apples hold their shape beautifully and taste amazing when baked.
Water: Just 2 tablespoons helps the apples get tender and juicy while baking.
Fresh lemon juice: One tablespoon keeps your apples from browning and adds a bright, fresh taste that balances the sweetness.
Frozen yogurt or low-fat vanilla yogurt: An 8-ounce container for serving. This creamy addition makes each bite feel like a special treat!
How to Make Apple Crumble with Oats

Step 1: Preheat your oven to 350 degrees F. In a medium bowl, mix together the oats, flour, 2 tablespoons brown sugar, and cinnamon with a fork. Add the cold butter pieces and work them in with your fingers or the fork until you see little clumps forming. This is the fun part – don’t worry about making it perfect!
Step 2: In a large bowl, gently toss the apple wedges with water, lemon juice, and the remaining 1 tablespoon of brown sugar. Make sure all the apples get coated evenly. Transfer this sweet apple mixture to a 9-inch pie plate and spread it out nicely.
Step 3: Sprinkle your oat mixture evenly over the apples – it should look like a cozy blanket covering them. Bake for 40 to 45 minutes until the topping turns golden brown and the apples feel tender when you poke them with a fork. Serve warm with a dollop of yogurt if you’d like!
Easy and Quick Apple Crumble Version
Want to make this even faster? You can use pre-sliced apples from the store to save chopping time! Just toss 4 cups of apple slices with the water, lemon juice, and brown sugar. You can also make the crumble topping ahead of time and store it in the fridge for up to 3 days. When you’re ready to bake, just assemble and pop it in the oven!
Serving Ideas
This apple crumble is perfect on its own as a complete dessert. Try serving it with a scoop of vanilla frozen yogurt or a drizzle of warm caramel sauce. It also tastes amazing with a cup of hot coffee or spiced tea on a chilly evening.
Storage
Store any leftovers covered in the fridge for up to 4 days. To reheat, just pop individual servings in the microwave for 30-45 seconds, or warm the whole dish in a 300°F oven for about 15 minutes. It tastes just as good the next day!
Substitutions
No Golden Delicious apples? Granny Smith or Honeycrisp work beautifully too! You can swap the brown sugar for Splenda Brown Sugar Blend if you’re watching your sugar intake. If you don’t have whole wheat pastry flour, regular all-purpose flour works just fine.
Pro Tips
- Keep that butter cold: Cold butter creates the best crumbly texture, so don’t let it sit out too long before mixing.
- Don’t skip the lemon juice: It keeps your apples looking fresh and adds a lovely brightness to balance the sweetness.
- Make it individual: Divide everything between 6 ramekins for cute personal servings – just bake for about 35 minutes instead.
- Leave the peels on: Apple skins add extra fiber and vitamins, plus they save you prep time!
FAQs
Can I make this ahead of time?
You bet! You can assemble the whole crumble and keep it covered in the fridge for up to a day before baking. Just add a few extra minutes to the baking time since it’ll be starting cold.
What if my topping isn’t getting golden?
No worries! Just move your dish to the top rack for the last 10 minutes of baking. Keep an eye on it so it doesn’t get too dark.
Can I use quick oats instead of regular rolled oats?
Sure! Quick oats will work, but you won’t get quite the same chunky texture. Regular rolled oats really make the topping special, so I’d stick with those if you have them.
Is this really diabetes-friendly?
Yes! With only 148 calories per serving and natural apple sweetness, plus the fiber from the oats and apple skins, this is a great choice for anyone managing their blood sugar.
