1½ cups butter softened
1 cup unsweetened cocoa
5 cups confectioner’s sugar
½ cup milk
2 teaspoons vanilla extract
½ teaspoon espresso powder
Add cocoa to a large bowl or bowl of stand mixer. Whisk through to remove any lumps.
Cream together butter and cocoa powder until well-combined.
Add sugar and milk to cocoa mixture by adding 1 cup of sugar followed by about a tablespoon of milk.
After each addition has been combined, turn mixer onto a high speed for about a minute. Repeat until all sugar and milk have been added.
Add vanilla extract and espresso powder and combine well.
If frosting appears too dry, add more milk, a tablespoon at a time until it reaches the right consistency.
If it appears to wet and does not hold its form, add more confectioner’s sugar, a tablespoon at a time until it reaches the right consistency.
