Method
- Preheat oven to 350°F (175°C). Line two 12-cup muffin tins with paper cupcake liners.
- In a large bowl, whisk together flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder until combined.
- In a separate bowl, combine milk, vegetable oil, eggs, and vanilla extract, whisking until smooth.
- Pour wet ingredients into dry ingredients and mix on medium speed for 2 minutes until smooth.
- Carefully stir in hot coffee until just combined - batter will be thin.
- Fill cupcake liners 2/3 full using a scoop for even distribution.
- Bake 18-22 minutes until toothpick inserted comes out with moist crumbs.
- Cool in pans 5 minutes, then transfer to wire racks to cool completely.
- For vanilla frosting: Beat softened butter 3 minutes until fluffy. Gradually add powdered sugar.
- Add vanilla and heavy cream, beat on high 3-4 minutes until smooth and fluffy.
- For chocolate coffee frosting: Beat softened butter until fluffy. Add powdered sugar, cocoa powder, and espresso powder.
- Add heavy cream and beat on high 3-4 minutes until smooth and creamy.
- Fill two piping bags with each frosting, then place both bags into a larger piping bag fitted with star tip.
- Pipe swirls onto cooled cupcakes, starting from outer edge and working inward for marbled effect.
- Serve immediately or store in airtight container at room temperature up to 2 days.
Notes
For best results, ensure all ingredients are at room temperature. The thin batter is normal and creates ultra-moist cupcakes. Store unfrosted cupcakes up to 5 days refrigerated, or freeze up to 3 months.
