A cookie monster cake is a unique and tasty way to celebrate a birthday. The basic cake is simple to make, and while the decorations are easy as well, it takes a bit of patience to create the frosting fur. The great thing about this cake is that cookies and other goodies are part of the decorations, so there's even a tasty dessert for people who don’t like cake. This recipe can also be adapted into other characters by changing the frosting color and the decorations.
