This is dedicated to all the chocolate and peanut butter lovers! This 3 layer cake features our decadent fudge brownie as the bottom layer, and our moist chocolate cake as the other two layers. We fold in chopped peanut butter cups into our smooth rich creamy peanut butter mousse and put the mousse between each layer. We top if off with chunks of brownies and drizzle glossy chocolate ganche over them and sprinkle peanut butter chips on top. This cake will definitely be a talking piece at your next gathering.
