This easy apple crumble with oats is everything a cozy fall dessert should be — tender, cinnamon-spiced apples tucked under a golden, buttery oat topping, with barely 15 minutes of hands-on prep before the oven takes over. I first made it because my little ones couldn’t manage biting into a whole apple, and it’s been our go-to ever since: no eggs, no nuts, no fuss, and endlessly forgiving. Serve it warm with a scoop of ice cream and watch it disappear.
Oriana’s Thoughts On The Recipe
I actually stumbled into this recipe out of necessity. I had a bowl of apples about to turn, and my kids — little at the time — just couldn’t manage biting into a whole apple. So I cooked them down, scattered a simple oat topping over them, and that humble little dish has been on repeat in our kitchen every fall since. It’s the kind of dessert that feels special without asking anything of you.

Apple Crumble vs. Apple Crisp: What’s the Difference?
The short version: a crumble has a topping made with flour, while a crisp has a topping made with oats — and this recipe happily lives in both worlds. My topping uses rolled oats and flour together, so you get the golden crunch of an oat topping with the tender, buttery structure of a classic crumble. Call it whichever you like; it bakes up cozy and golden either way.
The Buttery Oat Crumble Topping
This topping is the heart of the recipe. I use a combo of rolled oats and all-purpose flour — the oats crisp up at the edges while the flour binds everything into those tender, buttery clumps. My method is easy: stir the dry ingredients together, then pour in melted butter and mix just until the topping looks like damp, clumpy sand that holds together when you press it. Those little clumps are what bake into the craggy, golden bits everyone fights over. Scatter it loosely over the apples and resist the urge to pack it down — loose and craggy is exactly what you want.
The Best Apples for Apple Crumble
I reach for Granny Smith apples nine times out of ten — they’re tart and firm, so they hold their shape and balance the sweet topping instead of collapsing into mush. If you like a sweeter filling, Honeycrisp, Braeburn, or Jonagold are lovely too, or mix tart and sweet for the best of both. Whatever you choose, a firm, crisp apple always beats a soft, mealy one.
Rolled Oats vs. Quick Oats
I use old-fashioned rolled oats for that hearty, chewy-crisp texture. Quick oats work in a pinch, but they’re finer, so the topping comes out a little more sandy and less craggy. Skip instant oats — they go soft and lose the texture we’re after.
Food Allergy Swaps
This recipe is naturally egg, nut, peanut, soy, and sesame-free, making it suitable for most dietary needs. However, always check labels for hidden allergens.
- Dairy-Free: To make this recipe dairy-free, you can easily swap out the dairy ingredients for non-dairy alternatives.
- Butter: Substitute butter with dairy-free butter substitutes. Miyoko’s Creamery Organic Vegan Butter and Earth Balance Vegan Buttery Sticks are my favorite butter substitutes for baking.
- Gluten-Free: Use a gluten-free, all-purpose flour blend. Look for a gluten-free flour blend specifically formulated for baking, as it will have the right combination of flours and starches to mimic the texture of wheat flour. My favorite is Better Batter Original Blend. I also like Doves Farm Freee Gluten-Free All-Purpose Flour, but this blend does not contain xanthan gum, so you need to add 1/4 teaspoon of xanthan gum per cup (140 g) of gluten-free flour blend. Be sure to use certified gluten-free oats.
Process Overview: How To Make Apple Crumble with Oats Step-by-Step
Step 1 – Preheat oven to 350°F (180°C) and grease a 9×9 dish with butter.
Step 2 – Toss the apple wedges with the flour, cinnamon, maple syrup, and lemon juice until glossy; spread evenly in the dish.
Step 3 – Stir the oats, flour, brown sugar, baking powder, cinnamon, and salt together, pour in the melted butter, and mix until damp and clumpy. Scatter loosely over the apples.
Step 4 – Bake 30–40 minutes, until deep golden and bubbling at the edges. Rest 10 minutes before serving.
Tips for the Best Apple Crumble
- Toss the apples with the flour and lemon before baking — the flour thickens the juices as they cook and the lemon keeps the apples bright.
- Stir the melted butter in just until clumps form; overmixing makes the topping dense instead of craggy.
- Don’t skip the 10-minute rest before serving — it lets the filling set so it’s spoonable, not soupy.
- For extra crunch, sprinkle a few extra oats over the top before baking.
- Doubling it? Use a 9×13 dish and add a few minutes to the bake time.
What to Serve With Apple Crumble
Apple crumble was born to be served warm with something creamy:
- A scoop of vanilla ice cream melting into the topping — the classic.
- A drizzle of caramel sauce for extra decadence.
- A dollop of whipped cream or warm custard.
- A hot mug of homemade apple cider on the side.
FAQs
Can I use quick oats instead of rolled oats?
Yes, in a pinch. Quick oats are finer, so the topping turns out a bit sandier and less craggy. Rolled (old-fashioned) oats give the best texture; skip instant oats, which go soft.
What are the best apples for apple crumble?
Firm, tart apples like Granny Smith hold their shape best. Honeycrisp, Braeburn, and Jonagold work well too — or mix tart and sweet. Avoid soft, mealy apples.
Is this apple crumble nut-free?
Yes! This recipe is made with oats and all-purpose flour — no nuts or nut flours. It’s egg-free and nut-free, so it’s friendly for most allergy tables.
Can I make it ahead of time?
Yes. Assemble it unbaked, cover, and refrigerate up to a day; bake straight from the fridge, adding a few extra minutes. You can also prep the topping separately and keep it chilled.
How do I store and reheat leftovers?
Cover and refrigerate up to 3–4 days. Reheat in a 350°F oven for 10–15 minutes to bring back the crisp topping (the microwave works but softens it).
Why isn’t my topping crunchy?
Usually too little butter or an overmixed topping. Stir in the melted butter just until you have damp, clumpy crumbs, and don’t press it flat over the apples—leave it loose and craggy.

Easy Apple Crumble with Oats
Equipment
Important
• For best results, I highly recommend using a kitchen scale to measure the ingredients.
Ingredients
Apple Filling:
- 6 Granny Smith apples, peeled, cored, and cut into wedges (about 1 kg)
- 1 tablespoon all-purpose flour
- 1/4 teaspoon ground cinnamon
- 1/4 cup (60 ml) maple syrup
- 1 tablespoon (15 ml) lemon juice
Crumble Topping:
- 1 cup (100 g) rolled oats
- 1 cup (125 g) all-purpose flour
- 1/2 cup (100 g) brown sugar, packed
- 1/2 teaspoon (2 g) baking powder
- 1 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 6 tablespoons (84 g) unsalted butter, melted
- Butter for greasing
Instructions
- Prep your pan and oven: Preheat the oven to 350°F (180°C) and grease a 9×9-inch ovenproof dish with butter.
- Toss the apples: Place the apple wedges in a bowl. Sprinkle over the flour and cinnamon, then pour in the maple syrup and lemon juice. Toss until every wedge is glossy and lightly coated, then spread them out evenly in the prepared dish.
- Make the crumble: In another bowl, combine the oats, flour, brown sugar, baking powder, cinnamon, and salt. Pour in the melted butter and mix until the topping is damp and clumpy — it should hold together when you press a bit between your fingers. Scatter it evenly over the apples, leaving it loose and craggy rather than packing it down.
- Bake: Bake for 30 to 40 minutes, until the top is deep golden brown and the filling is bubbling around the edges. If the top browns before the apples soften, tent loosely with foil.
- Rest, then serve: Remove from the oven, cover loosely with foil, and let it stand for 10 minutes before serving — this lets the apple syrup thicken so it's spoonable, not soupy. Serve warm, ideally with a scoop of vanilla ice cream.
- Dairy-Free: Swap the butter for a dairy-free butter block — my go-tos for baking are Miyoko’s Organic Vegan Butter and Earth Balance Vegan Buttery Sticks.
- Gluten-Free: Use a 1:1 gluten-free all-purpose blend like Better Batter Original. If your blend has no xanthan gum (like Doves Farm Freee), add 1/4 teaspoon per cup (140 g). Be sure to use certified gluten-free oats, too.
- Don’t pack the topping down. Left loose and clumpy, it bakes into those craggy golden bits; pressed flat, it turns dense.
- Firm, tart apples win. Granny Smith holds its shape; soft apples turn to mush over a 30–40 minute bake.
- The 10-minute rest isn’t optional. Straight out of the oven, the filling is loose — that short rest is what makes it hold together on the spoon.

My favorite apple dessert! Granny Smith apples give the perfect balance of sweet & tart.
Hello Bailey! I’m so happy to hear it’s your favorite apple dessert. Thank you for sharing your love for the recipe! 😊
Easy to follow recipe and very simple ingredients!
My crumble top did not crisp up for me for some reason in the 20min cook time so I added 8 more minutes, but it still wasn’t crispy, so I broiled it for 2 minutes, and that did the trick (but I almost burnt it! lol)… I also used a pastry cutter & fork to blend butter, so perhaps the oats did not get the same individual coating of butter had I used my fingers? I did feel I blended it well though….
Anyhoo – The final taste was DELICIOUS!! But CAUTION: you may need to use self control as it is easy to want to eat more than 1 serving in a sitting – It was SO GOOD!!!
