Method
Preparation
- Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with paper cupcake liners.
- In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt until well combined.
- In a large bowl, beat the softened butter and granulated sugar together until light and pale in color, about 3 to 4 minutes with an electric mixer.
- Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
- In a separate bowl, mix together the cooled espresso, whole milk, and sour cream until smooth.
- Gradually add the dry ingredients to the butter mixture in three parts, alternating with the espresso mixture. Start and finish with the dry ingredients, mixing until just combined.
- Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
Baking
- Bake for 18 to 22 minutes, or until a toothpick inserted into the center comes out clean. Let them cool in the pan for 5 minutes before transferring to a wire rack.
Frosting
- For the frosting, beat the softened butter until smooth and creamy. Gradually add the powdered sugar, beating on high until fluffy.
- Mix in the espresso, vanilla extract, and salt until well combined.
- Once the cupcakes are completely cooled, frost generously with the espresso buttercream and garnish with whole coffee beans if desired.
Notes
Make sure your butter and eggs are at room temperature for best mixing results. Store cupcakes in an airtight container at room temperature for up to 3 days, refrigerate for up to a week, or freeze for up to three months.
