Method
Prep and season the filling
- Preheat the oven to 375F, then grease a 9x13 baking dish so the topping doesn’t stick.
- Stir cinnamon, nutmeg, allspice, and lemon juice into the canned apple pie filling to brighten and season it, then spread the filling in the prepared dish.
Make and add the oat crumble
- Combine rolled oats, all-purpose flour, brown sugar, cinnamon, and salt in a mixing bowl.
- Cut in the cold cubed butter until chunky clumps form, then scatter the crumble generously over the apple filling.
Bake and rest
- Bake for 30-35 minutes until the topping is golden and the filling is bubbling around the edges.
- Rest 5 minutes, then serve warm with vanilla ice cream.
Notes
Pro tip: Keep the butter cold and stop mixing as soon as you get chunky clumps—this keeps the crisp crunchy instead of sandy. Store leftovers covered in the refrigerator up to 4 days; rewarm in the oven at 350F for 10 minutes. Freezing is possible for up to 2 months, but the topping may soften a bit after thawing. For a dairy swap, use vegan butter in the crumble for a similar texture.
