For the Brownies:

  • 2 ounces unsweetened chocolate, melted
  • 1/3 cup vegetable oil
  • 1 cup granulated sugar
  • 2 whole eggs
  • 3/4 cup all-purpose flour
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder

For the Mousse:

  • 3/4 cup mini marshmallows
  • 4 ounces semi-sweet chocolate chips
  • 1/4 cup milk
  • 1 cup heavy cream


  1. Prepare the Brownies: Preheat your oven to 350F 175C. Grease and flour an 8-inch square baking dish. In a bowl, combine the melted chocolate with vegetable oil. Mix in the sugar and eggs until well combined. Stir in the flour, salt, and baking powder. Pour the batter into the prepared pan and bake for 25-30 minutes, until a tester comes out mostly clean. Let the brownies cool completely.
  2. Make the Chocolate Mousse: In a saucepan over low heat, melt the marshmallows, chocolate chips, and milk, stirring occasionally. Once melted, remove from heat and let cool completely. In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold in the cooled chocolate mixture until well combined and stiff peaks reform.
  3. Assemble: Spread the chocolate mousse over the cooled brownies. Refrigerate for at least 2 hours to set before serving.

Serving Tips:

  1. Chill Before Serving: For the best texture and flavor, refrigerate the Chocolate Mousse Brownies for at least 2 hours before serving. This allows the mousse topping to set and ensures a firm yet creamy consistency.
  2. Slice Carefully: When slicing the brownies, use a sharp knife dipped in hot water and wiped dry between cuts. This helps to achieve clean and neat slices, preventing the mousse layer from smudging.
  3. Garnish Creatively: Enhance the presentation of Chocolate Mousse Brownies by garnishing them with grated chocolate shavings, cocoa powder dusting, or fresh berries. This adds visual appeal and a burst of flavor to each serving.
  4. Serve with Accompaniments: Accompany Chocolate Mousse Brownies with a dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of chocolate sauce for an extra indulgent touch. These accompaniments complement the richness of the brownies and enhance the overall dessert experience.
  5. Portion Control: Cut the brownies into smaller portions if serving as part of a dessert spread or buffet. This allows guests to enjoy a taste of indulgence without feeling overwhelmed by the richness of the dessert.

Storage Tips:

  1. Refrigerate Leftovers: Store any leftover Chocolate Mousse Brownies in an airtight container in the refrigerator to maintain their freshness and prevent the mousse from softening. They can be stored in the refrigerator for up to 3-4 days.
  2. Cover Well: To prevent the brownies from absorbing any odors or flavors from other foods in the refrigerator, cover the container tightly with plastic wrap or aluminum foil before placing it in the fridge.
  3. Avoid Freezing: While Chocolate Mousse Brownies can technically be frozen, the texture of the mousse may become compromised upon thawing. It’s best to enjoy them fresh or refrigerated for optimal taste and texture.
  4. Refresh Before Serving: Before serving leftover brownies, allow them to sit at room temperature for a few minutes to slightly soften and bring out their flavors. Garnish with fresh toppings if desired to enhance their appearance and taste.
  5. Serve Chilled: If serving leftover Chocolate Mousse Brownies, serve them chilled directly from the refrigerator for the best taste and texture. The cool temperature enhances the creaminess of the mousse and ensures a refreshing dessert experience.


  1. Can I use a boxed brownie mix for the base instead of making it from scratch?
    • Yes, you can use a boxed brownie mix as a convenient alternative. Follow the instructions on the package to prepare the brownie base before adding the chocolate mousse topping.
  2. Can I use milk chocolate instead of semisweet chocolate for the mousse topping?
    • Yes, you can use milk chocolate if you prefer a sweeter flavor. Adjust the amount of powdered sugar in the mousse topping to suit your taste preferences.
  3. How long do Chocolate Mousse Brownies last, and how should they be stored?
    • Chocolate Mousse Brownies can be stored in an airtight container in the refrigerator for up to 3-4 days. Make sure to cover them well to prevent them from drying out or absorbing any odors from the fridge.
  4. Can I freeze Chocolate Mousse Brownies for later?
    • While it’s possible to freeze Chocolate Mousse Brownies, it’s best to freeze them without the mousse topping. Wrap the cooled brownie base tightly in plastic wrap and aluminum foil before placing it in a freezer-safe container. Thaw the brownie base in the refrigerator overnight before adding the mousse topping and serving.
  5. Can I customize the toppings on Chocolate Mousse Brownies?
    • Absolutely! Feel free to get creative with the toppings. You can sprinkle chopped nuts, chocolate shavings, or fresh berries on top of the mousse layer for added texture and flavor. Alternatively, drizzle melted chocolate or caramel sauce over the brownies for a decadent finishing touch.
