Method
Prep and shortbread cups
- Preheat oven to 375F, then grease a 24-cup mini muffin tin.
- Combine all-purpose flour, powdered sugar, and salt, then cut in cold unsalted butter until crumbly.
- Add ice water a little at a time, then press the dough into mini muffin cups to form shells.
Cook apple filling
- Sauté apples with butter, brown sugar, cinnamon, nutmeg, and cornstarch for 5-7 minutes until thickened.
- Cool the apple filling completely before assembling.
Make oat topping and bake
- Combine rolled oats, flour, brown sugar, and cinnamon, then cut in cold butter until clumpy.
- Fill shortbread cups with apple filling, then top each with oat crumble.
- Bake for 18-20 minutes at 375F until golden, then drizzle with caramel sauce right after baking.
Notes
For the crispiest crumble, keep butter cold and avoid over-mixing the oat topping. Once baked, store covered in the fridge for up to 3 days and rewarm at 300F for 5 minutes. Freezing is not recommended because the shortbread can soften after thawing. For a lighter option, use reduced-fat butter and substitute part of the brown sugar with a no-sugar-added brown sugar blend if you want less sugar without changing the method.
