Peanut Butter Cup Cake
This cake features a peanut butter cake, topped with peanut butter frosting. The whole cake is then topped with chocolate ganache. To achieve the ridges that give this cake the peanut butter cup look, I used the origami technique of pouring ganache over accordion-folded card stock and pressing it to the sides of the cake. Once the ganache was set, I removed the paper to reveal the ridges.
