- ½ cup vegetable oil
- 1 teaspoon vanilla extract
- 1 teaspoon espresso powder
- 1 cup hot water
For the Chocolate Mousses:
- 4 large egg yolks
- 2 tablespoons granulated sugar
- 2 tablespoons cornstarch
- 1 teaspoon vanilla extract
- 2 cups heavy cream, divided
- 3.5 oz dark chocolate, chopped

How to Make Chocolate Mousse Layer Cake
Step 1: Make the Cake Batter
In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. In another bowl, whisk together the eggs, milk, sour cream, oil, and vanilla until smooth. Dissolve espresso powder in hot water and mix it into the wet ingredients. Combine wet and dry ingredients until smooth.
Step 2: Bake the Cake Layers
Preheat your oven to 350°F (180°C). Divide the batter evenly between two greased and lined 8-inch round cake pans. Bake for about 35 minutes or until a toothpick comes out clean. Let cool completely before trimming tops for flat layers.
Step 3: Prepare the Mousse Base
In a small saucepan over medium heat, combine 1 cup of cream with vanilla until steaming. In another bowl, whisk egg yolks with sugar and cornstarch until pale. Gradually add hot cream to yolk mixture to temper it then return to saucepan. Cook while stirring constantly until thickened into a custard.
Step 4: Melt Chocolate and Combine
Divide custard into two bowls—one for dark chocolate and one for white chocolate. Stir each until melted and smooth. Whip remaining cream to stiff peaks; fold half into each chocolate mixture to create two separate mousses.
Step 5: Assemble the Cake
Place one trimmed layer in a dessert ring or springform pan. Spread dark chocolate mousse over it evenly. Layer white chocolate mousse on top. Refrigerate for 30 minutes to set prior to adding second cake layer on top. Chill assembled cake for at least 4 hours or until fully set.
Step 6: Make the Ganache
Heat heavy cream in a saucepan until steaming; pour over chopped milk chocolate. Let sit for one minute then stir until smooth. Cool slightly until thickened but still pourable.
Step 7: Finish the Cake
Remove your cake from its mold or pan carefully. Pour ganache over top and gently smooth it out to edges without allowing it to drip down sides. Decorate as desired with chocolate curls or sprinkles before serving.
Now you have all you need to create your delicious Chocolate Mousse Layer Cake! Enjoy every decadent slice!

How to Perfect Chocolate Mousse Layer Cake
Making the perfect Chocolate Mousse Layer Cake requires attention to detail and a few helpful tips. Follow these suggestions for an exquisite result.
- Use room temperature ingredients: Bringing eggs, milk, and cream to room temperature helps create a smooth batter and mousse.

- Properly cool cake layers: Allowing your cake layers to cool completely prevents melting the mousse when assembling.
- Whip cream to stiff peaks: Properly whipped cream ensures that your mousses have the right texture, providing lightness.
- Chill between layers: Chilling the mousses for 30 minutes before adding each layer allows them to set properly and maintains structure.
- Decorate just before serving: To maintain freshness, wait until just before serving to add decorations like ganache or chocolate curls.

Common Mistakes to Avoid
Making a Chocolate Mousse Layer Cake can be simple, but certain missteps can lead to less-than-ideal results. Here are some common mistakes to avoid.
- Using cold ingredients: Starting with cold eggs or cream can affect the cake’s texture. Be sure to bring your ingredients to room temperature for better mixing and consistency.
- Overmixing the batter: Mixing the cake batter too much can make it dense. Mix just until the ingredients are combined for a light and airy cake.
- Not leveling the cake layers: Uneven cake layers can make assembly difficult and affect presentation. Use a serrated knife to trim the tops of the cakes for even layers.
- Skipping the chilling time: Not allowing the mousse to set properly can result in a runny filling. Make sure to refrigerate the assembled cake for at least 4 hours.
- Incorrect oven temperature: Baking at an incorrect temperature can lead to undercooked or overcooked cakes. Always preheat your oven and use an oven thermometer if needed.
