Method
Make the oat crumble crust
- Combine rolled oats, flour, brown sugar, and cinnamon, then drizzle in melted unsalted butter and toss until evenly moistened. The mixture should look sandy and clump slightly when pressed.
- Press the crust mixture firmly into a 9-inch springform pan. Use steady pressure to compact the base for clean slices.
- Refrigerate the crust for 20 minutes. Look for the crust to feel set and chilled to the touch.
- Reserve 1/2 cup of the crust mixture for the crumble topping. Set it aside at room temperature so it stays workable.
Make the no-bake cheesecake filling
- Beat cream cheese, powdered sugar, brown sugar, vanilla, and cinnamon until completely smooth. Stop when no lumps remain and the mixture looks glossy.
- Fold in whipped heavy cream until no streaks remain, then spread the filling over the chilled crust. Fold gently so the filling stays thick, airy, and level.
Assemble and chill
- Stir cinnamon and nutmeg into apple pie filling. The topping should look evenly speckled with spices.
- Spoon the spiced apple pie filling evenly over the cheesecake. Arrange it to cover the surface without pushing into the filling.
- Scatter the reserved oat crumble over the apple topping. The crumble should cover the top generously for a crunchy layer.
- Refrigerate for 6 hours or overnight before releasing from the springform. The center should feel firm when gently nudged and slice cleanly.
Notes
Pro tip: For the smoothest filling, beat the cream cheese until completely lump-free before folding in whipped cream. Store covered in the refrigerator for up to 4 days; freeze the cheesecake without the crumble topping only if needed (texture may soften after thawing). For a lighter option, use reduced-fat cream cheese and replace part of the heavy cream with an equal amount of plain Greek yogurt, keeping it whipped to stiff peaks.
