How to Make a Chocolate Mint Layer Cake
Preheat the oven and prepare the cake pans.
Use a mixer to combine the cake mix ingredients.
Divide the batter between the 3 cake pans and bake for 25-35 minutes. The cake is done when a toothpick inserted comes out clean.
Allow the cakes to cool completely before taking the cake out of the pans.
Use a cake leveler to remove the domes from the cake, then place one of the cake layers on the cake board.=sing a cake slicer, remove the domes from the cakes
Thin Mint Frosting
Use a mixer to beat together the frosting until it forms stiff peaks. This takes about 5-7 minutes.
Place the first cake layer on the cake board and then place 1 cup of frosting on the cake and smooth it out.
Place the 2nd layer of cake on top.
Repeat with the frosting and then add the next layer.
Scoop 1 1/2 cups of frosting into a bowl and then frost the rest of the cake.
Coat the bottom of the cake in the Thin Mint crushed cookies.
How To Make the Chocolate Ganache
Using a small pot, add the heavy cream and heat it until it is simmering.
Place the chocolate chips in a bowl and add the heated heavy cream.
Let it sit for 1 minute and then whisk it together well until it is smooth.
Gradually pour the chocolate ganache into drizzles over the top of the cake
Allow the ganache to harden and then pipe dollops of frosting ontop the top of the cake.
Place a cookie next to the dollops.
Cut into slices and enjoy.
Should I Use Dark Chocolate or Milk Chocolate With Mint?
The cake mix I like to use is a milk chocolate cake. If you prefer to use dark chocolate with mint, you can certainly use a dark chocolate cake recipe. Both will taste fantastic with the mint.
How Do You Freeze a Layer Cake?
If you want to freeze the layer cake, you want to slice the cake first. I do this so I can take a slice of cake out at a time. I like to freeze the slices of cake on a plate first. This keeps the plastic from sticking to the plastic when it is wrapped. Once the frosting is frozen, wrap the cake well in plastic wrap.
