So this Monster Cookie Cake literally leaves nothing out from the original cookie. It has ALL the same flavors. You have a chocolate chip oatmeal cake. It is then layered with peanut butter frosting, crushed M&M’s and topped with a pile of oatmeal cookies and M&M’s. Oh and lets not forget it’s also decorated on the sides with more cookies.
