If you love the combination of chocolate and peppermint, this Chocolate Candy Cane Cake is for you. Three moist layers of chocolate cake surround candy cane buttercream, and the whole thing is frosted with chocolate-mint frosting. A layer of chocolate curls and some mini candy canes give it the perfect finishing touch!

The candy cane pieces in the buttercream do tend to get sticky after about a day, so if you're wanting to make this in advance, try swapping the candy cane pieces for Andes peppermint crunch baking bits, or similar chocolate-mint pieces, instead of using sugar-based mint candies. If you make this swap, this cake keeps very well in the refrigerator for 3 to 4 days. Bring it to room temperature before serving.

A quick note about the frosting ingredients: this recipe calls for pasteurized egg whites. It is safe to consume egg whites without cooking them, as long as you make sure that the whites you buy are pasteurized. To save time, buy them in a carton--look for 100% egg whites, not liquid egg substitute. If you cannot find them in a carton, you can buy pasteurized eggs and separate them yourself. You’ll need about 5 to 6 large eggs to get the 3/4-cup called for in the recipe.


  • For the Chocolate Cake:
  • 6 ounces butter (room temperature)
  • 5 1/4 ounces (3/4 cup) granulated sugar
  • 5.62 ounces (3/4 cup) brown sugar
  • 3 eggs, (room temperature)
  • 1 tablespoon vanilla extract
  • 12 fluid ounces (1 1/2 cups) buttermilk, (room temperature)
  • 8 ounces (2 cups) all-purpose flour
  • 3 ounces (1 cup) unsweetened cocoa powder
  • 1 1/2 teaspoon baking soda
  • 3/4 teaspoon salt
  • For the Frosting:
  • 6 fluid ounces (3/4 cup) pasteurized liquid egg whites
  • 24 ounces (6 cups) powdered sugar
  • 1/2 teaspoon salt
  • 24 ounces (6 sticks or 3 cups) unsalted butter, at room temperature
  • 1 tablespoon vanilla extract
  • 2 teaspoons peppermint extract
  • 6 ounces unsweetened chocolate (melted and cooled)
  • 1 cup candy cane bits
  • 3 cups chocolate curls or chocolate sprinkles

Steps to Make It

To Make the Cake:

  1. Line three 9-inch cake pans with parchment paper and spray with nonstick cooking spray. Preheat the oven to 350 F.

  2. Add the butter and both sugars to the bowl of a large stand mixer fitted with a paddle attachment. Beat them together on medium-high speed, until light and fluffy, about 5 minutes. Add the eggs one at a time, beating well after each addition. Add the vanilla extract, and beat well until everything is fully incorporated.

  3. In a separate bowl, sift together the flour, cocoa powder, baking soda, and salt. With the mixer running on low, add a quarter of the sifted flour mixture. When the flour streaks have almost all disappeared, add a third of the buttermilk to the mixing bowl. When that’s incorporated, continue to add the drys and wets in an alternating pattern, ending with the dry ingredients.

  4. When the dry ingredients are nearly incorporated, stop the mixer. Scrape down the bottom and sides of the bowl with a rubber spatula, and finish mixing the cake by hand. Divide the batter between the prepared pans, and smooth it into an even layer. Bake the cakes for 22 to 25 minutes, until a toothpick inserted into the center comes out with just a few moist crumbs attached. Cool the cakes completely before using.

To Make the Frosting and Assemble:

  1. Combine the whites, powdered sugar, and salt in the bowl of a large stand mixer fitted with a paddle attachment. Mix everything together on low speed, until the sugar is moistened and no dry patches remain. Turn off the mixer, scrape down the sides and bottom of the bowl with a spatula, then turn the mixer to medium speed. Beat on medium for 5 minutes.

  2. After 5 minutes, turn the mixer to medium-low and start adding the softened room temperature butter, 1 to 2 tablespoons at a time. Once all of the butter is incorporated, add the vanilla extract and peppermint extract and mix it in. Stop the mixer and scrape down the bottom and sides once more. Turn the speed to medium and beat the buttercream for 10 minutes.

  3. Divide the buttercream in half. Add the candy cane bits to half of the frosting, and mix in the melted, cooled unsweetened chocolate to the other half.

  4. To assemble the cake, place one layer on a cake cardboard, and put it on a cake turntable, if you have one. Scoop half of the candy cane frosting on top of the cake, and spread it into an even layer. Place a second cake layer on the frosting, and spread the remaining candy cane frosting on top of the cake. Finally, add the third cake layer on top. Spread a very thin layer of chocolate frosting all over the top and sides of the cake—this is the “crumb coat,” to lock in any stray crumbs from the cake. Refrigerate the cake briefly, for about 30 minutes, so the crumb coat can firm up.

  5. Spread a thicker layer of frosting along the top and sides of the cake. It doesn’t have to be perfectly smooth, because we’re going to cover up any imperfections. Place the chocolate curls or chocolate sprinkles in a large shallow pie tin or bowl. Hold the cake in one hand, keeping it over the pie tin, and use the other hand to scoop up handfuls of chocolate sprinkles and press them into the sides of the cake, letting the excess drop back into the container.

  6. Transfer the remaining chocolate frosting to a piping bag fitted with a star tip, and pipe rosettes of frosting all along the outer edge of the cake. Press a mini candy cane into each rosette, and serve!
