How to Make Easy Chocolate Mousse Cake Recipe
Step 1: Preheat Your Oven
Start by setting your oven to 350°F. Prepping your pans now ensures they are ready when you need them. Grease and line two round cake pans with parchment paper for easy removal later.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt. This step is crucial as it evenly distributes the leavening agents throughout your dry mix, ensuring a nice rise in your cake.
Step 3: Combine Wet Ingredients
In another bowl, beat together eggs, vegetable oil, buttermilk, and hot coffee. The coffee really elevates the chocolate flavor while adding moisture. This mixture should be smooth and well combined before moving on.
Step 4: Bring It Together
Pour the wet ingredients into the dry ingredients and blend until smooth. Don’t overmix; we just want everything combined nicely!
Step 5: Bake the Cakes
Divide your batter between the prepared pans and bake in your preheated oven for about 25–30 minutes. Keep an eye on them! Once done, let them cool completely in their pans on a wire rack.
Step 6: Prepare Your Mousse
Gently melt your semisweet chocolate using a double boiler or microwave. Allow it to cool slightly before folding it into whipped cream that’s been beaten with powdered sugar and vanilla until stiff peaks form.
Step 7: Layer It Up!
Once your cakes have cooled completely, place one layer in a springform pan. Spread half of your mousse on top. Add the second cake layer and repeat with more mousse. Cover everything tightly with plastic wrap and refrigerate for at least three hours until set.
Step 8: Make Your Ganache
Heat heavy cream until hot but not boiling. Pour it over chopped bittersweet chocolate along with corn syrup and butter; stir until smooth and glossy. This ganache will be poured over your chilled cake later.
Step 9: Finish Your Cake
Once set, pour the ganache over the top of the chilled cake allowing it to drip down the sides beautifully.
Step 10: Serve With Style
Slice using a hot knife for clean edges—nobody wants messy pieces! Enjoy every decadent bite of this Easy Chocolate Mousse Cake Recipe with friends or family!
Now you’re all set to create something truly special! Happy baking!
Pro Tips for Making Easy Chocolate Mousse Cake Recipe
Creating the perfect chocolate mousse cake is all about attention to detail and a dash of love. Here are some tips to ensure your cake turns out wonderfully every time!
-
Use room temperature ingredients: Bringing eggs, buttermilk, and cream to room temperature allows for better incorporation, resulting in a smoother batter and fluffier mousse.
-
Don’t overmix the batter: Gently blend your wet and dry ingredients until just combined. Overmixing can lead to a dense cake instead of the light, airy texture we want.
-
Chill your mixing bowl and beaters: For an extra fluffy mousse, chill your mixing bowl and beaters before whipping the cream. Cold equipment helps the cream whip faster and maintain its volume.
-
Layer carefully: When adding mousse between cake layers, be gentle to avoid disturbing the layers below. This helps maintain that beautiful presentation when you slice into the cake.
-
Use a hot knife to slice: For clean cuts, dip your knife in hot water and wipe it dry before slicing. This technique ensures that each piece looks as gorgeous as it tastes!

Side Dishes
- Coffee: A rich cup of coffee pairs beautifully with chocolate desserts, enhancing their flavors while providing a warm contrast.

- Fruit salad: A refreshing fruit salad made with seasonal fruits offers a light contrast that cleanses the palate after each decadent bite.
