Description
Delicious chocolate cake layered with fluffy marshmallow filling and rich ganache.
Ingredients
Scale
- 1 ¾ cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder (preferably Dutch-processed)
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup buttermilk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup hot coffee or boiling water
- 1 cup unsalted butter, softened
- 2 cups powdered sugar
- 1 ½ cups marshmallow creme
- 2 tablespoons heavy cream
- 1 ½ cups semi-sweet chocolate chips or chopped chocolate
- ¾ cup heavy cream
Instructions
- Preheat oven to 350°F (175°C) and grease two 9-inch square pans. Line with parchment paper.
- In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- In a separate bowl, beat eggs, buttermilk, oil, and vanilla extract until combined.
- Gradually mix wet ingredients into dry. Add hot coffee or water and stir until smooth. Batter will be thin.
- Divide batter into pans and bake for 30–35 minutes or until a toothpick comes out clean. Cool in pans for 10 minutes, then fully on a wire rack.
- For the filling, beat butter until fluffy, then add powdered sugar. Fold in marshmallow creme and heavy cream. Chill if needed.
- For the ganache, heat heavy cream until just simmering. Pour over chocolate and let sit for 1 minute, then stir until smooth.
- Assemble cake by spreading filling over one cake layer, topping with the second layer, and spreading ganache over the top.
- Chill cake for at least 30 minutes before slicing. Bring to room temperature before serving.
Notes
- Store leftovers in an airtight container in the refrigerator.
