How to Make Chocolate Mousse Brownies Recipe

Set your oven to 325 degrees

Use parchment paper to line a 8 x 8 baking dish and evenly spray with non-stick spray. Leave some edges to be able to pull out the mouse before cutting.

On medium speed using an electric mixer beat the eggs until fluffy and a light yellow color. Add in sugar and beat again. Add your remaining ingredients and mix.

Pour in the ingredients into the prepared dish and bake for 30-35 minutes.

A toothpick should come out with a few crumbs, you do not want to over bake. Let the brownies cool in the dish.

Combine the gelatin and water in a small bowl. Let rest and bloom for at least 10 minutes.

Bring the water to a light boil. Pour in the chocolate to a heat-safe bowl that fits in your pot. Place over the pot to melt the chocolate and stir. Take away from the heat when melted.

Put your cream in a small saucepan and boil. Mix in the gelatin to the hot cream until completely dissolved. Take away from heat.

Combine all your mixtures together and pour in half the mix at a time. Stir until smooth.

Use an electric mixer to mix the remaining heavy cream until soft peaks form. Once cooled, fold in with a spatula.

Pour your mixture over the brownies and smooth it with a spatula. For 6 hours, place in the refrigerator.

Lift the mousse out of the pan using the parchment paper edges. Dust some cocoa powder on top (Optional). Run a sharp knife in cold water and slice into bars. You may need to repeat with the knife under cold water between each cut.
