Method
Make the cupcakes
- Heat the oven to 350°F.
- Line a standard 12-cup muffin pan with paper liners.
- Whisk the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt in a medium bowl.
- Whisk the egg, buttermilk, oil, and vanilla in a separate bowl.
- Whisk the egg mixture into the dry ingredients just until combined.
- Whisk in the hot coffee until the batter is smooth; it will be thin.
- Divide the batter evenly among the liners, filling each about halfway.
- Bake for 18 to 22 minutes, until the tops spring back when lightly pressed and a toothpick inserted in the center comes out with a few moist crumbs.
- Cool the cupcakes in the pan for 5 minutes.
- Transfer the cupcakes to a wire rack and cool completely.
Make the peppermint frosting
- Beat the softened butter in a medium bowl until smooth and creamy.
- Beat in the powdered sugar gradually.
- Add the peppermint extract, salt, and heavy cream, then beat until fluffy.
- Spread or pipe the frosting onto the cooled cupcakes.
- Sprinkle with the crushed peppermint candies.
Notes
Let the cupcakes cool completely before frosting so the frosting stays fluffy and in place. Store covered in the refrigerator for up to 3 days; freezing is suitable. For a dairy-free variation, use dairy-free butter and cream and a dairy-free buttermilk substitute.
