Cookies and Cream Layer Cake with Mousse and Ganache

Chocolate Ganache

17. Place the dark chocolate in a bowl. Heat the heavy cream and pour it over the chocolate.

Assembling the Cake

20. Pipe a border of frosting around the edge to create a barrier for the mousse.
21. Spread a generous layer of cookies & cream mousse in the center.
22. Repeat for the remaining layers, assembling each with frosting edges and mousse
