Death by Chocolate Rocky Road Cake

rocky road cake

This cake is ALWAYS a hit…one of my favorite basic chocolate cake recipes, with chocolate buttercream, but it’s the toppings that make people go crazy! Something about seeing it topped with nuts, chocolate chips and marshmallows, makes this cake extra special. It’s SUPER rich, so I only frost the top and middle to help reduce the chocolate coma. 😉
