How to make Chocolate Mousse Brownies
Ingredients:
- 1 cup unsalted butter
- 1 cup granulated sugar
- 2 cups packed brown sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1/4 teaspoon salt
- 1 cup heavy cream
- 8 oz semi-sweet chocolate, chopped
- 1/2 cup heavy cream (for ganache)
- 4 oz semi-sweet chocolate (for ganache)
Directions:
- First things first: crank up your oven to 350°F (175°C), and find a 9×13 inch baking pan. Grease it like you just won the lottery!
- In a medium saucepan, press that butter and sugar together like they’re old friends over medium heat until they melt into a sweet symphony.
- Remove the pan from the heat and let those flavors simmer down—stir in the eggs and vanilla extract until combined.
- Now, mix in the flour, cocoa powder, and salt until you can barely see the flour. Less is more—let’s keep it rich!
- Pour that luscious brownie batter into your prepared pan, spreading it with care like you’re laying down a canvas for the next masterpiece.
- Bake in the preheated oven for about 20-25 minutes, or until a toothpick returns with a few moist crumbs. Let them cool completely, while you pop on your favorite playlist and dance like nobody’s watching!
- For the heavenly mousse, melt the chocolate in a heatproof bowl over simmering water. It’s a slow dance that enhances the flavor.
- In another bowl, whip the heavy cream until soft peaks start to form. This is the cloud upon which your mousse will rise—soft, fluffy, and oh-so-inviting! Fold the melted chocolate into the whipped cream until they become one, like two travelers who meet on the road and decide to embark on an adventure together.
- Spread that divine mousse over the cooled brownies like a soft blanket, then refrigerate for at least 2 hours while you dream of chocolaty visions.
- For the ganache, heat the remaining heavy cream until it simmers but doesn’t boil—remove from heat, and whisk in the chopped chocolate until it’s smooth and glossy like a serene lake reflecting the evening sun.
- Allow the ganache to cool just enough to handle, then pour it over the mousse layer, spreading evenly with the grace of a painter finishing a masterpiece.
- Chill once more for an hour. Then, slice these glorious creations into squares, ready to be devoured!
