How to Make Easy Chocolate Mousse Cake

Ingredients:

  • 8 tablespoons unsalted butter (120 grams)
  • 1 cup granulated sugar (200 grams)
  • 3/4 cup cocoa powder (84 grams)
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract
  • 2 large eggs
  • 1/2 cup all-purpose flour (60 grams)
  • 1/4 cup granulated sugar (50 grams)
  • 2 cups cold heavy whipping cream (480 mL, divided)
  • 1 teaspoon vanilla extract
  • 6 ounces chopped semisweet chocolate (about 1 cup, not chocolate chips)
  • 2 large eggs

Directions:

  1. Preheat your oven to 325°F. Spray a 9-inch round springform pan with nonstick cooking spray.
  2. In a microwave-safe bowl, combine the diced butter, 1 cup granulated sugar, and 3/4 cup cocoa powder. Microwave for 30 seconds, stir, then heat for another 30 seconds until the butter is melted and the mixture is smooth.
  3. Stir in the salt and 1 teaspoon vanilla extract.
  4. Add 2 eggs, mixing vigorously until the mixture is glossy and combined.
  5. Sprinkle the flour over the top. Stir vigorously for at least 50 strokes.
  6. Pour the mixture into the prepared springform pan, smoothing the top. Bake for 29–32 minutes until a toothpick inserted into the center comes out with moist crumbs. Let the brownie base cool completely in the pan.
  7. For the mousse, beat 2 eggs with 1/4 cup granulated sugar in a large bowl until pale and thick.
  8. In a separate bowl, beat in half of the cold heavy cream (1 cup) until just combined with the egg mixture.
  9. Pour this mixture into a saucepan and cook over medium heat while stirring constantly, until just thickened (3–4 minutes).
  10. Remove from heat, add the chopped chocolate, cover, and let it sit for 1 minute. Whisk until smooth.
  11. Chill the chocolate mixture in the refrigerator for about an hour until it’s cooled and slightly thickened.
  12. In a clean bowl, beat the remaining 1 cup cold whipping cream until soft peaks form.
  13. Break the chilled chocolate mixture into pieces and gradually mix it into the whipped cream. Add the final teaspoon of vanilla extract.
  14. Spread the mousse evenly over the cooled brownie base in the springform pan. Refrigerate for at least an hour before serving.
  15. Carefully remove the springform pan ring, slice, and serve your beautiful cake. Store leftovers in the fridge.

Tips to Make Easy Chocolate Mousse Cake

  • Make sure to let the brownie base cool completely before adding the mousse on top for better layering.
  • Use a good quality chocolate for the mousse; this can really enhance the flavor.
  • If you’re short on time, you can make the brownie base a day before and assemble the cake the next day.

Variation

For a unique twist, consider adding a layer of raspberry puree between the brownie and the mousse or mix in some orange zest to the chocolate mousse for a refreshing hint of citrus.

FAQs

Can I use chocolate chips instead of chopped chocolate?

While you can use chocolate chips, chopped chocolate will melt better and give a smoother mousse texture.

How do I know when the brownie base is done baking?

A toothpick inserted into the center should come out with a few moist crumbs but not wet batter.

Can I freeze the Easy Chocolate Mousse Cake?

It’s not recommended to freeze the mousse, as it may change texture. However, you can freeze the brownie base and then prepare the mousse fresh when you’re ready to assemble the cake.

Enjoy making and indulging in this fantastic Easy Chocolate Mousse Cake! Your friends and family will surely be impressed.
