How to make mint chocolate chip cupcakes


What you need
- Cupcake batter: You’ll use brown sugar, eggs, buttermilk, and vanilla extract to create the wet batter. You’ll use flour, cocoa powder, instant espresso powder, baking powder, and salt for the dry ingredients.
- Mint buttercream frosting: You need powdered sugar, butter, green food coloring, peppermint extract, vanilla extract, shaved dark chocolate, and a bit of whole milk or heavy cream.
- For decorating: I save a bit of the shaved dark chocolate and sprinkle it on top with festive St. Patrick’s Day sprinkles!






How to make it
- Step 1: First, sift together the flour, cocoa powder, baking powder, salt, and espresso powder.
- Step 2: Make the wet batter. Start by beating the brown sugar and butter together. Beat in two eggs and then add the buttermilk and vanilla extract. Mix with an electric mixer until smooth.


- Step 3: Add the dry ingredients and mix until just combined. Don’t overwork the flour!


- Step 4: Bake the cupcakes. Line a cupcake tin and fill each liner about ⅔ of the way full. Bake for 20 to 23 minutes or until a toothpick inserted into the center of a cupcake comes out clean. Remove and transfer the cupcakes to a wire rack to cool completely.



- Step 5: Make the frosting. When the cupcakes have cooled completely, combine the powdered sugar, butter, green food coloring, vanilla extract, and peppermint extract in a large bowl. Beat with an electric mixer until smooth, adding 4 to 5 tablespoons of whole milk to thin out the frosting as needed. Fold in finely chopped dark chocolate until combined.



You can pipe or spoon the frosting onto the cupcakes and garnish with the remaining dark chocolate and sprinkles.
