Method
Make oat crumble
- Mix oats, flour, brown sugar, and cinnamon, then cut in cold butter until crumbly. Refrigerate the crumble while you make the cupcake batter.
Make apple cupcake batter
- Beat softened butter with brown sugar until well combined. Beat in eggs one at a time.
- Add applesauce, sour cream, and vanilla, mixing until smooth and thick.
- Fold in dry ingredients and then fold in finely diced apple just until no dry streaks remain.
Bake cupcakes
- Heat oven to 375°F and line a sheet pan with cupcake liners. Fill each liner about 2/3 full, then top with oat crumble.
- Bake at 375°F for 20-22 minutes, until the centers spring back and the crumble looks lightly browned with crisp edges. Let cupcakes cool completely.
Frost and finish
- Pipe cinnamon cream cheese frosting around the edge of each cupcake once completely cool, creating a ring that holds the topping. Spoon or drizzle caramel over the tops right before serving.
Notes
Pro tip: chill the oat crumble so the butter firms up—this helps it bake into a crisp, bakery-style crown. Store cupcakes covered in the fridge for up to 4 days; freeze unfrosted cupcakes (wrap tightly) for up to 2 months, then thaw and frost. For a lighter option, use low-fat cream cheese and swap in reduced-fat sour cream.
