This comforting cinnamon apple crisp feels like autumn in every mouthful, blending soft apples with a crunchy buttery oat topping. It's my quick fix when visitors show up or when the family wants something sweet but easy. Each spoonful is pure cozy right out of the oven.
I first made this one rainy afternoon. Cinnamon scent took over the kitchen and the whole family cleaned out the pan. Now they always ask for it when the holidays come around.

Smart Storage
Keep any extras in a covered container in the fridge for up to five days. Warm it up in the microwave or oven so it tastes freshly made. Planning to freeze? Let it cool completely then wrap well and store frozen for up to a month.
Swap Options
Got gluten restrictions? Use gluten free flour instead of all purpose. Try pears for a fresh spin. Not into super sweet? Cut the brown sugar or swap for maple syrup for an earthier vibe.

Recipe FAQs
- → Is it necessary to peel the apples?
If you want your apples soft and smooth, peel them. For extra fiber and a bit more chew, keep the skins on. It’s really just what you like best.
- → How should leftovers be stored?
Let everything cool down, cover it up, and keep it in the fridge. When you’re ready, reheat a bit in the oven or microwave—or dig in cold if you’re into that.
- → Can I substitute the oats with another ingredient?
If you don't have oats, chopped nuts or some extra flour will do for some extra crunch. Skipping the oats just makes your topping a bit heavier. Still good!
- → What type of apples work best?
All kinds work, but firm apples like Granny Smith or Honeycrisp keep their shape in the oven and hit that perfect tart-sweet spot.
- → What can be served alongside this dessert?
A scoop of vanilla ice cream, a swirl of whipped cream, or a bit of caramel sauce on top make this a sweet treat you might want every night.
