Step‑by‑Step Instructions for Easy Chocolate Mousse Cake
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). While it heats, prepare two 8-inch round cake pans by greasing and flouring them or lining them with parchment paper. This ensures your Easy Chocolate Mousse Cake will easily release without any sticking.
Step 2: Mix Dry Ingredients
In a large mixing bowl, sift together 2 cups of all-purpose flour, 1 ¾ cups of granulated sugar, ¾ cup of cocoa powder, 1 ½ teaspoons of baking powder, 1 ½ teaspoons of baking soda, and 1 teaspoon of salt. Whisk until the dry ingredients are well combined and evenly distributed, giving your cake a uniform texture.
Step 3: Combine Wet Ingredients
In another bowl, whisk together 2 large eggs, 1 cup of vegetable oil, 1 cup of buttermilk, and 1 cup of hot coffee. Make sure these ingredients are well combined, as they will add moisture and rich chocolate flavor to the cake, enhancing your Easy Chocolate Mousse Cake’s richness.
Step 4: Blend Wet and Dry Mixtures
Gently fold the wet ingredients into the dry mixture using a spatula. Mix until just combined, ensuring you don’t overmix; it’s okay if there are a few lumps. This step will keep your cake light and fluffy, a key characteristic of a great chocolate mousse cake.
Step 5: Bake the Cake
Divide the batter evenly between the prepared cake pans. Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for about 10 minutes before transferring them to a wire rack to cool completely.
Step 6: Make the Mousse
While your cakes cool, melt 8 ounces of semisweet chocolate in a microwave or double boiler until smooth. Let it cool slightly. In a separate bowl, whip 2 cups of cold heavy cream with ½ cup of powdered sugar and 1 teaspoon of vanilla extract until stiff peaks form, creating the luscious mousse for your Easy Chocolate Mousse Cake.
Step 7: Fold Chocolate into Cream
Gently fold the cooled melted chocolate into the whipped cream mixture, using a spatula. Take care not to deflate the whipped cream too much; you want to keep that airy texture that makes the mousse light and delightful.
Step 8: Layer the Cake
To assemble the Easy Chocolate Mousse Cake, place one layer of cake on a serving platter or in a springform pan. Spread half of the chocolate mousse evenly on top. Carefully layer the second round of cake and then spread the remaining mousse over the top, smoothing it out for a beautiful finish.
Step 9: Chill to Set
Refrigerate the assembled cake for at least 3 hours, allowing the mousse to set properly. For the best results, chill it overnight. This waiting period enhances flavor and texture, making each slice of your Easy Chocolate Mousse Cake even more enjoyable.
Step 10: Prepare Ganache
Before serving, make the ganache by heating 1 cup of heavy cream until it begins to simmer. Remove from heat and add in 8 ounces of bittersweet chocolate, stirring until melted and smooth. Mix in 2 tablespoons of corn syrup and 2 tablespoons of butter to achieve a shiny, glossy finish.
Step 11: Top the Cake
Remove your chilled cake from the refrigerator. Pour the ganache evenly over the cake, letting it drip down the sides for that irresistible look. Allow it to set for a few moments, then slice your Easy Chocolate Mousse Cake and present it to your delighted guests!
