- All-purpose flour
- Dutch-process cocoa powder
- Baking powder
- Baking soda
- Salt
- Granulated sugar
- Vegetable or canola oil
- Eggs
- Vanilla extract
- Peppermint extract
- Buttermilk
- Hot water
Mint Chocolate Chip Buttercream
- Unsalted butter
- Powdered sugar
- Milk
- Peppermint extract
- Green gel food coloring
- Dark or semisweet chocolate, finely chopped
Instructions
- Prepare the Cake Pans
- Preheat the oven to 350°F.
- Grease your cake pans thoroughly with nonstick spray and line the bottoms with parchment paper circles to prevent sticking.
- If available, wrap the pans with cake strips to help the layers bake evenly.
- Mix the Dry Ingredients
- In a medium mixing bowl, combine the flour, cocoa powder, baking powder, baking soda, and salt.
- Whisk thoroughly until the ingredients look evenly blended with no visible cocoa lumps remaining.
- Set the bowl aside temporarily.
- Combine the Wet Ingredients
- In a separate large bowl, whisk together the granulated sugar and oil until smooth.
- Add the eggs one at a time, mixing well after each addition.
- Stir in the vanilla extract and peppermint extract until fully incorporated.
- Build the Batter
- Add part of the dry ingredient mixture into the wet ingredients, followed by part of the buttermilk.
- Continue alternating between the dry ingredients and buttermilk until everything combines into a smooth batter.
- Slowly pour in the hot water while stirring carefully. The batter will become very thin, which helps create a moist cake texture.
- Bake the Cakes
- Divide the batter evenly between the prepared cake pans.
- Place the pans into the oven and bake until the cakes rise fully and a toothpick inserted into the center comes out clean.
- After baking, let the cakes rest in the pans for about 30 minutes.
- Carefully turn the cakes out onto a cooling rack and chill them before frosting.
- Make the Mint Buttercream
- Place the softened butter into a large mixing bowl and beat until creamy and smooth.
- Gradually mix in the powdered sugar one cup at a time.
- Add the milk and peppermint extract, then continue mixing until fluffy.
- Mix in a few drops of green gel food coloring until the frosting reaches a soft mint green shade.
- If desired, add a tiny amount of blue and brown gel coloring for a more natural mint appearance.
- Add the Chocolate Pieces
- Finely chop the chocolate into tiny bits.
- Gently shake away excess chocolate dust before adding the chocolate to the buttercream.
- Fold the chocolate pieces carefully into the frosting until evenly distributed.
- Assemble the Cake
- Trim the tops of the cake layers if needed for even stacking.
- Spread a thick layer of mint buttercream between each layer.
- Stack the cakes carefully, then chill briefly so the frosting firms up slightly.
- Cover the outside of the cake with another thick layer of buttercream.
- Use an offset spatula to smooth the frosting gently instead of a scraper, since the chocolate pieces can drag through the frosting.
- Decorate and Serve
- Top the cake with extra chopped chocolate if desired.
- Slice and serve chilled or slightly cool for the best texture and flavor.
Notes
- Properly measuring flour helps prevent dry cake.
- Buttermilk creates a softer and richer texture.
- Gel food coloring works better than liquid food coloring.
- Finely chopped chocolate mixes into the frosting more smoothly.
- Chill the cake layers before frosting for easier assembly.
