This decadent Peppermint Chocolate Cake combines all-time favorite Best Chocolate Cake Ever, peppermint buttercream, and peppermint bark for a festive cake perfect for the holidays!
Prepare chocolate cake as instructed. Allow to cool completely. As cake is cooling, prepare peppermint buttercream frosting.
Peppermint Buttercream Frosting
Place softened butter into the bowl of a stand mixer that has been fitted with the paddle attachment. Turn the mixer on a medium setting and cream the butter until it is smooth and has lightened in color, about 3 minutes.
Add confectioner’s sugar, ½ a cup at a time. After each cup has been incorporated, turn the mixer onto the highest speed setting and for about 10 seconds to lighten the frosting.
Add peppermint extract and a pinch of salt and combine until well-incorporated.
Add milk, heavy cream or half-and-half until the frosting has reached the preferred consistency. For a firmer frosting, add more confectioner’s sugar, a ¼ cup at a time. For a softer frosting, add more milk or cream, a tablespoon at a time.
Frost cake and sprinkle chopped peppermint bark on top of cake as garnishment (optional).
Notes
Notes:The cake batter will be very thin after adding the boiling water. This is correct and results in the most delicious and moist chocolate cake I’ve ever tasted! For 3 layers - I split the cake batter between 3 cake pans instead of 2. For 3 layers, check the cake for doneness after about 25 minutes.Nutrition for 1 serving of cake with frosting. Storage Tips:To store: Store the cake under a cake dome on the countertop for 3 to 4 days.To freeze: Let the baked cake layers cool completely. Wrap them well with plastic wrap and then with foil. Put each layer into a freezer bag and freeze for up to 2 months. To serve, thaw in the refrigerator overnight with wrapping intact. The next day, the layers are ready to fill and frost.
