Instructions

Step 1: Make the Brownie Base

Preheat oven to 350°F (175°C). Line an 8×8-inch (20×20 cm) pan with parchment paper.

In a mixing bowl, whisk together melted butter, sugar, eggs, and vanilla until smooth.

Add cocoa powder, flour, salt, and baking powder. Stir until just combined.

Pour batter into the prepared pan and spread evenly.

Bake for 20–25 minutes until a toothpick comes out with a few moist crumbs. Cool completely.

Step 2: Prepare Banana Mousse

In a small bowl, mash bananas and mix with lemon juice, sugar, and vanilla. Set aside.

In another small bowl, sprinkle gelatin over cold water and let it bloom for 5 minutes.

Gently warm the gelatin mixture (microwave 10–15 seconds or use a small saucepan) until completely dissolved. Stir into banana mixture.

Whip heavy cream to stiff peaks. Gently fold whipped cream into the banana mixture until smooth and fluffy.

Step 3: Assemble & Chill

Pour banana mousse over the cooled brownie base.

Smooth the top and refrigerate for at least 4 hours, or overnight, until set.

Step 4: Serve

Cut into bars using a sharp knife (wipe between cuts for clean edges).

Garnish with banana slices, chocolate curls, or a dusting of cocoa powder.
