Method
Prep and preheat
- Preheat the oven to 375°F and grease a 9x13 baking dish.
- Stir cinnamon, nutmeg, allspice, and lemon juice into the canned apple pie filling, then spread it in the prepared dish.
Make the oat crumble
- Combine rolled oats, all-purpose flour, brown sugar, cinnamon, and salt until evenly mixed.
- Cut the cold unsalted butter into the oat mixture until chunky clumps form.
- Scatter the crumble generously over the apple filling.
Bake, rest, and serve
- Bake for 30-35 minutes, until the topping is golden and the filling is bubbling around the edges.
- Rest for 5 minutes before serving warm.
- Serve with vanilla ice cream.
Notes
For the best texture, keep the butter cold while making the crumble so it forms clumps instead of a sandy layer. Refrigerate leftovers in an airtight container for up to 4 days; reheat in a 350°F oven until warmed through. Freezing is not recommended for the crumble texture. For a dairy-light option, use vegan butter sticks in the topping (still cold) while keeping serving ice cream optional.
