How to Make Easy Chocolate Mousse Cake Recipe
Step 1: Preheat the Oven and Prepare Pans
Set your oven to 350°F (175°C) and prepare your round cake pans by greasing them lightly. Preparing the pans ensures that your cake layers will come out perfectly without sticking.
Step 2: Whisk Dry Ingredients Together
In a large bowl, whisk together the sifted flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. This step helps evenly distribute the leavening agents throughout the flour for a light and fluffy cake.
Step 3: Beat Wet Ingredients Together
In another bowl, beat together the eggs, vegetable oil, buttermilk, and hot coffee until fully combined. The hot coffee enhances the chocolate flavor while also adding moisture to the batter.
Step 4: Combine Dry and Wet Mixtures
Gently blend the dry ingredients into the wet mixture until just smooth. Be careful not to overmix; we want our cake to be tender!
Step 5: Bake the Cake Layers
Divide the batter evenly between your prepared pans. Bake for 25–30 minutes or until a toothpick inserted comes out clean. Allow them to cool completely on wire racks before moving on.
Step 6: Melt Chocolate for Mousse
While your cakes cool down, gently melt the semisweet chocolate in a microwave or double boiler. Let it cool slightly before adding it to whipped cream.
Step 7: Whip Cream for Mousse
In another bowl, beat cold heavy whipping cream with powdered sugar and vanilla extract until stiff peaks form. This will give our mousse its light texture.
Step 8: Fold Chocolate into Whipped Cream
Carefully fold the melted chocolate into your whipped cream until fully combined. This folding technique keeps air in the mixture so that our mousse stays fluffy.
Step 9: Assemble Your Cake Layers
Place one layer of cake in a springform pan. Spread half of the mousse on top before adding another layer of cake followed by remaining mousse. Repeat as desired!
Step 10: Refrigerate Until Set
Cover with plastic wrap and refrigerate for at least three hours or overnight if you can resist! Chilling allows everything to set beautifully.
Step 11: Prepare Ganache Topping
To make ganache, heat heavy cream until steaming but not boiling. Pour over finely chopped bittersweet chocolate and stir until smooth.
Step 12: Finish Your Cake
Spread ganache over your chilled mousse cake carefully ensuring an even layer across the top for that glossy finish!
Step 13: Slice & Enjoy!
When it’s time to serve, cut slices using a hot knife—this helps achieve clean edges! Enjoy every delicious bite of your creation!
Pro Tips for Making Easy Chocolate Mousse Cake Recipe
Creating the perfect chocolate mousse cake can be a breeze with just a few handy tips!
-
Use High-Quality Chocolate: The flavor of your cake depends largely on the chocolate you choose. Opt for high-quality semisweet and bittersweet chocolate to ensure a rich, decadent taste.
-
Room Temperature Ingredients: Make sure your eggs and buttermilk are at room temperature before mixing. This helps create a smoother batter that rises evenly while baking.
-
Don’t Overmix: When combining wet and dry ingredients, mix until just combined to prevent a dense cake. A light touch will keep your cake fluffy and airy.
-
Chill Thoroughly: Allow the mousse to set in the refrigerator for at least 3 hours (or overnight if you can wait!). This ensures the layers hold together beautifully when sliced.

Hot Knife for Slicing: Warm up your knife under hot water before slicing the cake. Wiping it clean between cuts will give you those pristine edges that look so impressive!
