Method
Make the cupcakes
- Heat the oven to 350°F.
- Line a standard 12-cup muffin pan with paper liners.
- Whisk the flour, baking powder, baking soda, cinnamon, and salt in a medium bowl.
- Whisk the oil and brown sugar in a large bowl until combined.
- Whisk in the eggs one at a time.
- Whisk in the sour cream and vanilla.
- Stir the flour mixture into the wet mixture just until no dry streaks remain.
- Fold in the diced apple.
- Divide the batter among the liners, filling each about two-thirds full.
- Bake for 18 to 22 minutes, until the tops spring back when lightly touched and a toothpick inserted into the cake comes out with a few moist crumbs.
- Cool in the pan for 5 minutes.
- Transfer the cupcakes to a rack and cool completely.
Make the caramel frosting
- Beat the butter in a large bowl with an electric mixer until smooth.
- Gradually beat in the powdered sugar.
- Beat in 1/3 cup of the caramel sauce and the heavy cream until fluffy.
Frost and finish
- Spread or pipe the frosting onto the cooled cupcakes.
- Drizzle with the remaining 2 tablespoons caramel sauce.
Notes
For a neat finish, make sure the cupcakes are completely cool before frosting. Store covered in the refrigerator for up to 4 days; freeze unfrosted cupcakes for up to 2 months. For a dairy-free variation, use dairy-free sour cream, butter, heavy cream, and caramel sauce.
