Ingredients
- 1/2 box Devil’s Food Cake mix
- 1/2 cup water
- 6 Tbsp. unsalted butter, melted
- 2 eggs
- 1/2 cup unsalted butter, softened
- 1 cup confectioners' sugar
- 1 (7.5-oz) jar Marshmallow Fluff
- 1 tsp. vanilla extract
- pinch of salt
- 1 1/2 cups chocolate chips
- 3/4 cup heavy cream
Directions
- Step 1Preheat oven to 350 degrees F. Butter two 8” round baking pans and line each with parchment paper. Butter the bottom and sides of the pans and dust with flour.
- Step 2Combine cake mix, water, melted butter and eggs in a medium bowl. Whisk using a hand mixer until smooth. Divide batter between pans. Bake for 15-20 minutes, until toothpick inserted in center comes out clean. Cool for 10 minutes in the pans, then invert cakes onto cooling racks to cool completely.
- Step 3While the cake is baking, make filling and ganache. To make filling, combine softened butter, confectioners' sugar, fluff, vanilla and salt in the bowl of a stand mixer. Beat until smooth and fluffy.
- Step 4To make ganache, place chocolate chips in a medium, heatproof bowl and set aside. Heat heavy cream in a small saucepan over medium heat. When bubbles begin to break the surface around the edges of the pan, turn off the heat. Pour the hot cream over chocolate chips, whisking constantly until the sauce is smooth.
- Step 5Top one round cake with marshmallow frosting, then place the second cake on top of it. Pour ganache over the cake.
