  • 1 cup unsalted butter Softened (for frosting)
  • 3 cups powdered sugar For frosting
  • ¾ cup cocoa powder For frosting

Equipment

  • 1 Muffin tin 12-cup capacity

  • 1 Whisk Manual
  • 1 Electric mixer For frosting
  • 1 Piping bag With star tip

Method
 

  1. Preheat oven to 350°F and line a muffin tin with 12 paper liners.
  2. Whisk flour, sugar, cocoa, baking soda, baking powder, and salt in a large bowl.
  3. Whisk eggs, buttermilk, oil, and vanilla in a separate bowl; pour into dry ingredients.
  4. Slowly pour in hot coffee while whisking gently until batter is smooth and thin.
  5. Fill liners ⅔ full and bake for 18–20 minutes; cool completely.
  6. Whip butter, cocoa, powdered sugar, and cream until fluffy; pipe onto cupcakes.

Notes

Do not overfill the cupcake liners; the batter is thin and rises significantly. Ensure the cupcakes are completely cool before piping the frosting to prevent melting.
