Ingredients

Scale

For the Espresso Brownie Cupcakes

  • 1/2 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 2 large eggs, at room temperature
  • 1 teaspoon vanilla extract
  • 1 tablespoon instant espresso powder
  • 1/2 cup brewed espresso or strong coffee, cooled
  • 1 cup all-purpose flour
  • 1/4 cup unsweetened cocoa powder
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt

For the Coffee Buttercream

 

  • 1 cup unsalted butter, softened
  • 2 1/2 cups powdered sugar
  • 1 tablespoon instant espresso powder
  • 1 tablespoon brewed espresso, cooled
  • Pinch of salt
  • Optional: cocoa powder or chocolate shavings for topping

Instructions

  1. Get the oven and pan ready.
    Heat the oven to 350°F (175°C). Line a standard 12-cup muffin tin with cupcake liners so the batter is ready to portion as soon as it is mixed.
  2. Cream the butter and sugar.
    Place the softened butter and granulated sugar in a large bowl. Beat them together until the mixture becomes pale, fluffy, and well blended. This gives Espresso Brownie Cupcakes a lighter texture from the start.
  3. Add the eggs and flavor base.
    Crack in the eggs one at a time, mixing well after each addition so the batter stays smooth. Stir in the vanilla extract, then add the espresso powder and the cooled brewed espresso. Mix again until everything looks evenly combined.
  4. Whisk the dry ingredients separately.
    In another bowl, combine the flour, cocoa powder, baking powder, baking soda, and salt. Whisk until the mixture looks even and free of cocoa clumps.
  5. Bring the batter together.
    Add the dry ingredients to the wet mixture in stages, mixing gently after each addition. Stop mixing as soon as the batter comes together. For Espresso Brownie Cupcakes, less mixing gives you a softer crumb.
  6. Portion the batter.
    Divide the batter evenly among the cupcake liners, filling each one about two-thirds full. This helps the cupcakes rise nicely without overflowing.
  7. Bake the cupcakes.
    Place the pan in the oven and bake for 16 to 18 minutes. Check for doneness with a toothpick; it should come out clean or with a few moist crumbs attached. Do not overbake if you want the cupcakes to stay tender.
  8. Cool before frosting.
    Leave the cupcakes in the pan for about 5 minutes, then transfer them to a wire rack. Let them cool all the way before adding any frosting.
  9. Make the buttercream.
    Beat the softened butter in a clean mixing bowl until smooth and creamy. Add the powdered sugar gradually, mixing on low at first so it does not puff everywhere. Once the sugar is incorporated, mix in the espresso powder, brewed espresso, and salt. Beat the frosting until it turns light, fluffy, and easy to pipe.
  10. Decorate the cupcakes.
    Spread or pipe the buttercream over the cooled cupcakes. Finish with cocoa powder, chocolate shavings, or any topping you like. That final layer makes these Espresso Brownie Cupcakes look polished and bakery-ready.

Notes

  • Use room temperature eggs and butter for a smoother batter.
  • Let the espresso cool before mixing it in.
  • Sift the dry ingredients if the cocoa looks lumpy.
  • Start checking the cupcakes early so they stay moist and soft.
