For the Whipped Cream Filling:
- 6 oz. cream cheese
- 1 cup confectioners sugar
- 16 oz. heavy whipping cream
- 2 teaspoons unflavored gelatin (optional – to stabilize the whipped cream filling)
- 2 tablespoons cold water (optional – to stabilize the whipped cream filling)
For the Ganache Icing:
- 1 cup heavy whipping cream
- 8 oz. semi-sweet chocolate (I used two 4-oz. Ghirardelli semi-sweet baking-quality chocolate bars)
Instructions
Step 1: Preparing the Cake
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a large mixing bowl, combine buttermilk, water, oil, sugar, eggs, baking soda, and salt. Mix until well combined.
- Sift in the flour and cocoa, then mix until the batter is smooth.
- Divide the batter evenly between the prepared pans.
- Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean.
- Allow the cakes to cool completely before assembling.
Step 2: Creating the Whipped Cream Filling
- In a mixing bowl, beat the cream cheese until smooth.
- Add confectioners sugar and continue to beat until well combined.
- In a separate bowl, whip the heavy cream until stiff peaks form.
- If desired, stabilize the whipped cream by dissolving gelatin in cold water and adding it to the whipped cream.
- Gently fold the whipped cream into the cream cheese mixture until smooth and creamy.
Step 3: Assembling the Cake
- Place one cooled cake layer on a serving platter.
- Spread the whipped cream filling evenly over the first layer.
- Top with the second cake layer.
Step 4: Making the Ganache Icing
- In a saucepan, heat the heavy whipping cream until it just begins to boil.
- Place the chocolate in a heatproof bowl and pour the hot cream over it.
- Let it sit for a minute, then stir until the chocolate is completely melted and smooth.
- Allow the ganache to cool slightly before pouring it over the assembled cake, letting it drip down the sides.
Cook Notes and Variations
- Nutty Crunch: Add chopped nuts like walnuts or hazelnuts to the whipped cream filling for added texture.
