Christmas candy meets Christmas cake in this minty, chocolaty, decadent peppermint bark cake recipe.
Melt your chocolate and 1/4 cup oil over a double boiler, or in the microwave (my preference) at 50% power for 1 minute, then stir. Microwave in additional 30 second intervals (50% power) as needed until the chocolate is completely melted. Set aside.
Remove the cakes from the oven and allow to set in the pan 10-15 minutes before inverting onto a cooling rack to cool completely. I like to wrap the cakes while still slightly warm and chill in the refrigerator 2 hours before decorating.
When you are ready to decorate, make your frosting.
Melt together the heavy cream and white chocolate in a double boiler or the microwave (50% power, 1 minute, stir, add 20 second intervals as needed). Set aside.
In a mixing bowl with a hand mixer, or the bowl of your stand mixer with a paddle attachment, cream the butter until light and fluffy. Scrape the sides of the bowl.
Pour in the white chocolate ganache and stir to combine. Add the powdered sugar 1 cup at a time until the desired consistency is reached. Then stir in the peppermint extract.
Torte the cake (cut the layers in half), so you have 4 equal discs. Place one on a cake board, top with a layer of frosting, cover with a layer of cake. Repeat twice more with the remaining cake layers.
Add a thin layer of frosting all around the cake, then chill it for 10-15 minutes to help the frosting set. Add the final layer of frosting, and crushed candy detailing at the bottom (optional) and return the cake to the refrigerator to chill.
Make your dark or semisweet chocolate ganache using either the double boiler or microwave method and set aside until it's not hot, but still pourable.
Remove the cake from the refrigerator and pour the ganache into the center of the top of the cake. Use a teaspoon or offset spatula to encourage the ganache towards the edges of the cake. Allow it to drip down the cake naturally. Work quickly as the ganache will set on the chilled cake - this is an easy way to get drips that stop part way down the cake.
Add peppermint bark pieces as decorations when you are about ready to serve. The cake may be stored covered at a cool room temperature up to 3 days
I have used white chocolate chips in a pinch. They take longer to melt, but you can still achieve good results.
