Ingredients
Brownie Base
- 3/4 cup butter
- 1 ½ cups granulated sugar
- 1 tablespoon vanilla extract
- 2 large eggs
- 3/4 cup all-purpose flour (properly measured)
- 1/2 cup unsweetened cocoa powder
- 1/2 teaspoon salt
Mousse Topping
- 3/4 cup miniature marshmallows
- 4 ounces semi-sweet baking chocolate (chopped)
- 1/4 cup milk
- 1 cup cold heavy whipping cream
Instructions
- Prepare Brownies: Preheat the oven to 350°F (175°C). Grease or line a 9×9-inch baking pan with parchment paper to ensure easy removal of the brownies after baking.
- Melt Butter: In a large saucepan, melt the butter over medium heat until fully melted and smooth.
- Add Sugar: Reduce the heat to low and stir in the granulated sugar. Cook this mixture for 2-3 minutes, stirring constantly to blend and slightly dissolve the sugar, making the brownies extra moist.
- Add Vanilla: Remove the pan from heat and stir in the vanilla extract to infuse flavor.
- Cool Mixture: Let the butter and sugar mixture cool for about 5 minutes ensuring it doesn’t cook the eggs when added.
- Add Eggs: Whisk in the eggs until the mixture is smooth and fully combined.
- Mix Dry Ingredients: Add the all-purpose flour, cocoa powder, and salt. Whisk together gently until just incorporated to avoid overmixing, which keeps brownies tender.
- Bake Brownies: Pour the batter into the prepared pan and spread evenly. Bake for 20-30 minutes. The edges should appear set and slightly firm, while the center remains shiny and fudgy. Insert a toothpick; it should come out with a few moist crumbs.
- Cool Completely: Remove the brownies from the oven and allow them to cool completely in the pan to set properly before adding mousse.
- Prepare Mousse: In a medium saucepan over low heat, combine miniature marshmallows, chopped semi-sweet chocolate, and milk. Stir constantly until the mixture is smooth and glossy. Remove from heat and let cool completely.
- Whip Cream: In a separate chilled bowl, beat the cold heavy whipping cream until stiff peaks form for a light, fluffy mousse texture.
- Combine Mousse: Gently fold the cooled chocolate marshmallow mixture into the whipped cream ensuring it is evenly mixed without deflating the cream.
- Assemble Dessert: Spread the mousse evenly over the cooled brownie layer with a spatula for a smooth finish.
- Chill: Refrigerate the assembled brownies for at least 30 minutes to allow the mousse to set firmly before serving.
- Store Leftovers: Cover the brownies and keep refrigerated to maintain freshness for up to 3 days.
Notes
- Ensure the brownie batter is not overbaked to keep a fudgy center.
- Use chilled heavy cream for best whipping results.
- Cooling the chocolate mixture thoroughly before folding into the whipped cream prevents melting and keeps mousse airy.
- For easier removal, lift the brownies out using parchment paper overhang.
- Leftover brownies can be stored in an airtight container in the fridge for up to 3 days.
- For a richer mousse, use high-quality semi-sweet chocolate.
