To assemble this cake you will need a baked 9″ round chocolate cake sliced into two 1/2″ high layers. My rich chocolate cake works wonderfully in this dessert as the recipe produces a cake with a deep chocolate flavor and color.

Tips for the Perfect Chocolate Mousse Cake:

• Chocolate: Use a high-quality chocolate as it will produce a more natural flavoring which will shine through in the end product. Supermarket chocolate chips may be used in a pinch or to save on costs. Also, it is best to weigh the chocolate on a food scale. Using measuring cups will not be as accurate as chocolate pieces come in various sizes.

• Simple Syrup: I recommend applying a simple syrup to each layer of the cake. This will keep the cake moist during the various stages of assembling the dessert and super-moistened layers pair perfectly with the texture of the chocolate mousse.
