Easy Steps to Make Chocolate Mousse Layer Cake
Start by preheating your oven to 350°F (175°C). In a bowl, beat the eggs and sugar together for about 3 to 4 minutes until the mixture is light and fluffy. Sift the flour, cocoa powder, and baking powder into the bowl, then gently fold everything together. Add the melted butter and mix it in, then pour the batter into a 20 cm baking pan. Bake for 20 to 25 minutes, then let the cake cool in the pan.
While the cake cools, prepare the mousse layers. Start by mixing gelatin with water and letting it sit for 5 minutes. In a separate saucepan, heat the cream and then mix in the melted chocolate until smooth. Add the gelatin mixture and stir until it dissolves. Whip the remaining cream to soft peaks and gently fold it into the chocolate mix. Pour the first layer of mousse over the cooled cake and refrigerate for about 30 to 40 minutes. Repeat this process for the milk chocolate mousse layer.
Next, prepare the chocolate ganache. Chop the dark chocolate and pour the hot cream over it. Stir until smooth and then pour this ganache over the cooled mousse layers. Refrigerate for at least 4 hours, or overnight if you can wait!
Finally, decorate your masterpiece with whipped cream, mini cookies, and chocolate shavings. Serve it cold with a steaming cup of espresso or Turkish coffee for the perfect finish.
