Ingredients You’ll Need
Before diving into the recipe, let’s gather everything you need for these Chocolate Mousse Brownies. Grab your measuring cups and let’s get baking!
- 1 cup unsalted butter (Use unsalted butter for better flavor control.)
- 2 cups granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1/2 teaspoon salt
- 1 cup heavy cream
- 8 ounces semi-sweet chocolate, chopped (Choose a good quality for rich flavor!)
- 1/4 cup powdered sugar (for the mousse)
- 1 teaspoon vanilla extract (for mousse)
- 1 cup semi-sweet chocolate chips (for ganache)

How to Make It
- Preheat the oven to 350°F (175°C) and grease a 9×13 inch baking dish. Feel that anticipation? You’re about to create something special!
- In a saucepan, melt together the butter and sugar over medium heat. Stir gently until combined. You’ll appreciate that sweet and buttery aroma; it’s heavenly!
- Remove the pan from heat, then mix in the eggs and vanilla extract until everything’s silky smooth.
- Sift in the flour, cocoa powder, and salt, stirring until fully combined; the batter will be thick and glossy. Pour it into your greased baking dish and smooth the top with a spatula. Can you feel the excitement building?
- Bake for 20-25 minutes. The edges should be firm, but the center will remain soft, and that’s just perfect. Allow the brownies to cool completely; I know, it’s tough to wait!
- For the mousse, melt the chopped chocolate over a double boiler or in the microwave. Let it cool slightly while you whip together the heavy cream and powdered sugar until soft peaks form. The sound of the mixer is music to my ears!
- Gently fold in the melted chocolate and vanilla into the whipped cream. Careful now—let that luscious creamy texture create a beautiful partnership.
- Spread the mousse over the cooled brownies and refrigerate for at least 2 hours. This is where the magic truly happens.
- For the ganache, melt the chocolate chips and heavy cream together until smooth, then pour over the mousse layer. The shiny layer of chocolate will have you swooning!
- Refrigerate until set. When ready, cut into squares and serve. Just look at that decadent layer of mousse peeking through!
Kitchen Tips
- One time-saving trick: Make the brownies a day ahead! They taste even better after resting in the fridge overnight.
- One fix for a common mistake: If the brownies begin to crack on top, no worries! That just means you’re making them even more enticing.
- One personal twist: Add a sprinkle of sea salt on top of the ganache for a mouthwatering sweet and salty contrast.
Serving Ideas
These Chocolate Mousse Brownies are perfect for any occasion, whether it’s a family dinner, Sunday brunch, or a cozy night in enjoying a movie. To elevate your presentation, serve them with fresh berries or a dollop of whipped cream on the side. Picture this: a warm brownie topped with fluffy mousse, paired with a scoop of vanilla ice cream—absolute bliss!
Storing & Leftovers
- Store in the fridge for up to 5 days, but I highly doubt they’ll last that long!
- If you need to store them for longer, freeze them for up to a month. Just be sure to wrap them well!
- For a fun leftover idea, try crumbling them over yogurt for a quick dessert. The combination of textures is to die for!
