Chocolate Mousse Brownies (Printable Version)

Fudgy brownie base layered with silky chocolate mousse and topped with glossy ganache for a decadent three-layer chocolate dessert.

# Ingredients:

→ Brownie Base

01 - 115g unsalted butter, melted
02 - 200g granulated sugar
03 - 2 large eggs
04 - 1 tsp vanilla extract
05 - 40g unsweetened cocoa powder
06 - 65g all-purpose flour
07 - 1/4 tsp salt
08 - 1/4 tsp baking powder

→ Chocolate Mousse

09 - 350ml heavy whipping cream, chilled
10 - 225g semisweet chocolate, finely chopped
11 - 45ml milk
12 - 25g powdered sugar

→ Ganache Topping

13 - 115g semisweet chocolate, finely chopped
14 - 120ml heavy cream

# Steps:

01 - Preheat oven to 175°C and line a 20×20 cm baking pan with parchment paper. Whisk together melted butter, granulated sugar, eggs, and vanilla until smooth. Sift in cocoa powder, flour, salt, and baking powder, then fold gently until just combined. Pour batter into prepared pan, smooth with a spatula, and bake for 20-25 minutes until a toothpick comes out with a few moist crumbs. Allow to cool completely in the pan.
02 - Heat milk until steaming but not boiling. Pour over chopped chocolate in a heatproof bowl, let sit for 2 minutes, then stir until melted and smooth. Cool to room temperature. In a separate bowl, whip heavy cream with powdered sugar until soft peaks form. Gently fold cooled chocolate into whipped cream until fully incorporated, being careful not to deflate the mixture. Spread evenly over the cooled brownie base and refrigerate for at least 2 hours until set.
03 - Place chopped chocolate in a heatproof bowl. Heat heavy cream until simmering, then pour over chocolate. Let sit for 2-3 minutes, then stir until smooth and glossy. Pour ganache over the set mousse layer and spread evenly with an offset spatula. Refrigerate for another hour until ganache is firm before serving.

# Notes:

01 - For clean slices, dip your knife in hot water and wipe dry between cuts.
02 - Allow brownies to sit at room temperature for 10-15 minutes before serving for the best texture and flavor.
