How to Make

Quick Overview

Creating your Chocolate Mousse Brownie Cake is a breeze! You’ll need a microwave, a mixing bowl, a whisk, and a 9-inch springform pan. In about 30 minutes of hands-on time and a bit of waiting for cooling and chilling, you’ll have a stunning cake ready to impress.

Ingredients for Chocolate Mousse Brownie Cake arranged on a countertop

Ingredients

. 8 tablespoons (120 grams) unsalted butter
. 1 cup (200 grams) granulated sugar
. 3/4 cup (84 grams) cocoa powder
. 1/2 teaspoon salt
. 1 teaspoon vanilla extract
. 2 large eggs
. 1/2 cup (60 grams) all-purpose flour
. 2 large eggs (for mousse)
. 1/4 cup (50 grams) granulated sugar (for mousse)
. 2 cups (480 mL) cold heavy whipping cream
. 1 teaspoon vanilla extract (for mousse)
. 6 ounces chopped semisweet chocolate (about 1 cup)

Instructions

  1. Preheat your oven to 325°F (160°C) and lightly grease a 9-inch round springform pan with cooking spray.
  2. In a microwave-safe bowl, combine the diced butter, sugar, and cocoa powder. Microwave on HIGH for 30 seconds, then stir and microwave again for another 30 seconds.
  3. Once melted, stir in the salt and vanilla extract. Add the two large eggs, mixing until smooth. Then, sprinkle the flour on top and stir vigorously for about 50 strokes until fully combined.
  4. Pour the brownie batter into the prepared springform pan and bake for 29-32 minutes. Let it cool completely before proceeding to the mousse layer.
  5. To prepare the mousse, beat the two large eggs with the 1/4 cup of sugar in a bowl for 2-3 minutes, or until the mixture is pale yellow.
  6. Gradually pour half of the cold heavy cream into the egg mixture. Cook on medium heat while stirring until it starts to thicken (do not allow it to boil).
  7. Remove from heat, add the chopped chocolate, and cover the bowl. Let it sit for 1 minute, then whisk until smooth. Chill this mixture in the refrigerator for about an hour.
  8. In another bowl, beat the remaining heavy cream until soft peaks form. Gently fold in the chilled chocolate mixture until just combined.
  9. Pour the mousse over the cooled brownie in the springform pan, spreading it evenly. Refrigerate for at least one hour before serving.
  10. When ready, release the springform pan and slice the cake to reveal the beautiful layers.

What to Serve with Chocolate Mousse Brownie Cake

Pair your Chocolate Mousse Brownie Cake with a scoop of vanilla ice cream or a dollop of whipped cream for an extra touch of sweetness. A light, refreshing salad or fresh berries can also balance the rich flavors nicely. For a drink, a nice cup of coffee or a glass of dessert wine works beautifully, enhancing the chocolate notes of the cake.

Top Tips for Perfecting Chocolate Mousse Brownie Cake

  1. Use Quality Chocolate: The better the chocolate, the richer your mousse will taste.
  2. Don’t Overbake the Brownies: Aim for a slightly fudgy texture for the best contrast with the mousse.
  3. Room Temperature Ingredients: Let your eggs sit at room temperature for a seamless mix.
  4. Cool Completely: Ensure the brownie layer is fully cooled to prevent the mousse from melting.
  5. Gently Fold Mousse: When combining the whipped cream with the chocolate mixture, be gentle to keep the airiness.
  6. Chill Thoroughly: Give the mousse ample time to set for the best flavor and texture.
  7. Decorate with Garnishes: Top with chocolate shavings, fresh berries, or mint for a visual appeal.

Storing and Reheating Tips

Store any leftovers in the refrigerator, covered, for up to 3-4 days. Chocolate Mousse Brownie Cake is best enjoyed chilled, so there’s no need to reheat it. If you want to enjoy it later, you can also freeze slices wrapped in plastic wrap and aluminum foil for up to 2 months. Just thaw in the refrigerator when you’re ready to indulge again.

FAQs

Q: Can I use milk chocolate instead of semisweet chocolate?

A: Absolutely! Milk chocolate will give the mousse a creamier flavor, but keep in mind that it will be sweeter.

Q: What can I substitute for heavy cream?

A: You can use coconut cream or a dairy-free whipping cream alternative, but the texture and flavor may vary.

Q: How do I know when the brownie layer is done?

A: Insert a toothpick into the center; it should come out with a few moist crumbs but not wet batter.

There you have it! The Chocolate Mousse Brownie Cake is not just a dessert, but a delightful experience that brings sweetness to any occasion. The process is simple, and the outcome is spectacular, making it a must-try for your next gathering or a special weekend treat. Don’t wait—indulge in this heavenly dessert soon!
