Method
- In a small saucepan, simmer raspberries, sugar, and lemon juice for 10–15 minutes until reduced by half. Press through a fine-mesh sieve to remove seeds. Chill completely.
- Preheat oven to 350°F (175°C). Line a cupcake pan. Whisk flour, sugar, cocoa powder, baking soda, and salt.
- Whisk egg, buttermilk, oil, and vanilla. Add to dry ingredients and mix just until combined.
- Slowly stir in hot coffee. Fill liners 2/3 full and bake 18–22 minutes. Cool completely.
- Core each cupcake and fill with chilled raspberry reduction. Replace cake tops.
- Beat butter until fluffy. Gradually add powdered sugar, then raspberry reduction. Whip until smooth and vibrant. Pipe onto cupcakes.
Notes
For best structure and flavor, ensure the raspberry reduction is fully chilled before using it in the frosting or filling.
