Ingredients
For the Mocha Cake:
- 1 ¾ cups all-purpose flour
- 1 ½ cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup whole milk
- ½ cup vegetable oil
- 2 teaspoons pure vanilla extract
- 1 cup boiling water
- 2 tablespoons instant coffee granules
For the Chocolate-Rum Cream Filling:
- 1 cup heavy whipping cream
- ½ cup powdered sugar
- ¼ cup unsweetened cocoa powder
- 2 tablespoons dark rum
- 1 teaspoon pure vanilla extract
For the Ganache:
- 1 cup semi-sweet chocolate chips
- ½ cup heavy cream
- 1 tablespoon unsalted butter (optional, for shine)
Instructions
Step 1: Prepare the Cake Batter
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Mix on medium speed until well combined.
- In a small bowl, dissolve the instant coffee granules in the boiling water. Gradually add this mixture to the batter, mixing until smooth. The batter will be thin.
Step 2: Bake the Cakes
- Divide the batter evenly between the prepared pans.
- Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.
Step 3: Make the Chocolate-Rum Cream Filling
- In a medium bowl, whip the heavy cream until soft peaks form. Gradually add the powdered sugar and cocoa powder, continuing to whip until stiff peaks form.
- Gently fold in the dark rum and vanilla extract until well incorporated.
Step 4: Prepare the Ganache
- In a small saucepan, heat the heavy cream until it just begins to simmer. Remove from heat and pour over the chocolate chips in a heatproof bowl. Let it sit for a few minutes, then stir until smooth. If desired, add butter for extra shine.
Step 5: Assemble the Cake
- Once the cakes are completely cooled, place one layer on a serving plate. Spread half of the chocolate-rum cream filling on top.
- Place the second cake layer on top of the filling. Spread the remaining cream filling on top, smoothing it out evenly.
- Pour the chocolate ganache over the top of the cake, allowing it to drip down the sides.
Step 6: Garnish and Serve
- For an elegant touch, decorate the top with chocolate shavings or cocoa powder.
- Slice, serve, and enjoy your Mocha Layer Cake with Chocolate-Rum Cream Filling!
