How to Make Chocolate Peppermint Cake
This Chocolate Peppermint Cake is a delightful symphony of rich chocolate and invigorating mint, surprisingly simple to master.

With a preparation time of about 30 minutes and baking time of 30-35 minutes, you’ll be enjoying this festive delight in no time.
Step-by-Step Instructions
Prepare the Cake Batter:
- Preheat and Prep Pans: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or one 9×13 inch baking pan. You can also line the bottoms with parchment paper for easy removal.
- Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking soda, baking powder, and salt. Ensure these ingredients are well combined to distribute the leavening agents evenly.
- Add Wet Ingredients (Except Boiling Water): To the dry ingredients, add the large eggs, buttermilk, vegetable oil, vanilla extract, and peppermint extract. Beat with an electric mixer on medium speed for about 2 minutes, until smooth and well incorporated. The batter will be thick at this stage.
- Incorporate Boiling Water: With the mixer on low speed, carefully pour in the boiling water. Continue to mix until the batter is smooth and thin. Do not overmix; you just want the water to be incorporated. The hot water helps to bloom the cocoa powder, intensifying the chocolate flavor and creating a wonderfully moist cake.
- Pour and Bake: Pour the batter evenly into the prepared cake pans. If using two 8-inch pans, divide the batter equally. Bake for 30-35 minutes for round pans, or 35-40 minutes for a 9×13 inch pan, or until a wooden skewer or toothpick inserted into the center comes out clean.
- Cool the Cakes: Let the cakes cool in their pans on a wire rack for about 10-15 minutes before inverting them onto the wire rack to cool completely. Ensure they are fully cooled before frosting.
Prepare the Peppermint Buttercream Frosting:
- Cream the Butter: In a large mixing bowl, beat the softened unsalted butter with an electric mixer on medium speed until light and fluffy, about 2-3 minutes.
- Add Powdered Sugar Gradually: Gradually add the sifted powdered sugar, about one cup at a time, beating well after each addition. The frosting will become quite thick.
- Incorporate Liquids and Extracts: Add the milk (or heavy cream), vanilla extract, peppermint extract, and pinch of salt. Beat on medium-high speed until the frosting is smooth, creamy, and spreadable. If the frosting is too thick, add a little more milk, a teaspoon at a time. If it’s too thin, add a little more sifted powdered sugar.
- Adjust Peppermint Flavor: Taste the frosting and add more peppermint extract if a stronger mint flavor is desired. Remember, a little goes a long way!
Assemble and Decorate:
- Frost the Cake: Once the cake layers (if using round pans) are completely cool, place one layer on your serving plate. Spread a generous amount of peppermint buttercream frosting evenly over the top.
- Add Second Layer (if applicable): Carefully place the second cake layer on top of the first. Frost the top and sides of the entire cake with the remaining buttercream.
- Decorate: Decorate the Chocolate Peppermint Cake as desired. Sprinkle crushed peppermint candies or candy canes around the edges or over the top for a festive crunch. Add chocolate shavings for an extra chocolatey touch, or a few fresh mint sprigs for a pop of color and aroma.
