How to Make Chocolate Mousse Cake

To create an indulgent Chocolate Mousse Cake, specific ingredients, instruments, and careful attention to detail are key. This guide provides a straightforward approach to crafting a luxurious dessert that balances a moist chocolate cake layer with rich chocolate mousse filling.

How To Make Chocolate Mousse Cake


For the chocolate cake layer:

  • 2 cups granulated sugar
  • 1-3/4 cups all-purpose flour
  • 3/4 cup unsweetened cocoa powder (you can use Dutch-processed for a deeper flavor)
  • 1-1/2 teaspoons baking powder
  • 1-1/2 teaspoons baking soda
  • 1 teaspoon salt
  • 2 eggs
  • 1 cup buttermilk (or milk with a tablespoon of vinegar or lemon juice as a substitute)
  • 1/2 cup canola oil (alternatively, any flavor-neutral oil)
  • 2 teaspoons pure vanilla extract
  • 1 cup boiling hot water (you may substitute with coffee for a richer taste)

For the chocolate mousse filling:

  • 1 teaspoon unflavored gelatin
  • 2 tablespoons cold water
  • 1 cup heavy whipping cream
  • 1/2 cup powdered sugar
  • 2 cups semi-sweet chocolate chips

To garnish (optional):

  • Chocolate sprinkles, fresh berries, or chocolate curls


  • Two 9-inch round cake pans
  • Parchment paper (for lining the pans)
  • Serrated knife (for leveling cakes)
  • Stand mixer or hand mixer
  • Microwave-safe bowl (for mousse preparation)
  • Springform pan or cake collar (for assembling)

Step by Step Instruction For Chocolate Mousse Cake

  1. Preheat your oven to 350°F (175°C). Line the bottom of each cake pan with parchment paper and lightly grease the sides.
  2. Mix together sugar, flour, cocoa powder, baking powder, baking soda, and salt in a large bowl.
  3. Add in eggs, buttermilk, oil, and vanilla extract. Beat until well combined.
  4. Gradually incorporate the boiling water or coffee, and continue stirring until the batter is smooth.
  5. Pour the batter evenly into the prepared pans and bake for about 30-35 minutes or until a toothpick inserted into the center comes out clean.
  6. While the cakes cool, prepare the mousse filling. Sprinkle the gelatin over cold water and let it stand for 5 minutes. Microwave for about 15 seconds, then set aside to cool slightly.
  7. Whip the heavy cream and powdered sugar together until stiff peaks form. Melt the chocolate chips and combine with the gelatin mixture. Fold into the whipped cream until no streaks remain.
  8. To assemble, place one cake layer on your serving plate. Spread a portion of the chocolate mousse on top, then add the second layer. Smooth the remaining mousse over the top and sides of the cake.
  9. Chill the cake for at least an hour to set. Before serving, garnish with optional chocolate sprinkles, fresh berries, or chocolate curls. Enjoy your decadent Chocolate Mousse Cake!

Ingredient Substitute For Chocolate Mousse Cake

When crafting a Chocolate Mousse Cake, you may need to switch out ingredients due to preferences or availability. Starting with flour, if a recipe calls for all-purpose flour and you only have cake flour, use 1 cup plus 2 tablespoons of cake flour for every cup of all-purpose flour.

For the sugar, if your recipe needs castor sugar and you only have granulated sugar, you can process the granulated sugar in a food processor until fine. When it comes to cocoa powder, a substitute isn’t straightforward, but carob powder can be a good alternative for a less rich flavor.

If you’re out of butter, you can use oils like coconut or canola. Use ¾ cup of oil for every cup of butter. When chocolate chips are scarce, you can chop up a bar of chocolate, remembering that 1 ounce of chocolate chips is about a tablespoon.

In the realm of dairy, for heavy cream, a mixture of milk and butter can suffice. Combine ¾ cup of milk with ¼ cup of melted butter to replace 1 cup of heavy cream. Milk itself can be substituted with almond, soy, or oat milk in equal amounts.

For vanilla extract, almond extract can work, but use half as much since it’s stronger. Lastly, if your recipe calls for salt and you’re out, in most baking recipes, you can skip it without much issue, although it may subtly affect the flavor balance.

Remember, it’s important for you to maintain the structure of your cake. These substitutes can alter texture and taste, so use these alternatives with care.

What to Serve with Chocolate Mousse Cake

When indulging in a luxurious Chocolate Mousse Cake, pairing it with complementary sides enhances your dessert experience. Ideal accompaniments balance the rich chocolate flavor and can bring a new dimension to your treat.

For a classic pairing, serve your cake with a dollop of whipped cream. Its light texture and subtle sweetness offset the chocolate’s richness. If it’s the holiday season, consider spicing the whipped cream with a hint of cinnamon or nutmeg for a festive touch.

If you’re seeking an added chocolate kick, a drizzle of warm chocolate ganache works wonders. It adds a silky smooth contrast to the mousse’s fluffy texture.

For a refreshing counterpart, try pairing with fresh berries. Raspberries or strawberries add a tartness that cuts through the sweetness and makes each bite of cake feel bright and balanced.

If you’re enjoying the cake after dinner, a cup of coffee is almost a must. Its bold, roasted flavors complement the deep chocolate, much like in a Peanut Butter Chocolate Cake.

For those who love a hint of fruit in their dessert, a slice of Berry Cake can be an excellent side. The light fruit flavors will provide a pleasant contrast without overwhelming the main event.

Lastly, consider a scoop of ice cream. Vanilla is a classic choice, but don’t shy away from trying flavors like caramel or berry to create a unique pairing.

To sum it up, when you choose a side for your Chocolate Mousse Cake, think about textures and flavors that will complement or contrast the main dessert for an unforgettable culinary experience.
