My cousin wanted me to make her a cookie monster birthday cake. I was intimated at first after seeing many ideas online, but this cake was one of the easiest cakes I have ever made. I made a 2 layered round cake and frosting the middle layer. Then I took a grass tip (tip 233) and made the fur. I used the largest round tip and made the eyes and mouth then I added the cookies. I do warn you if you are decorating the cake the night before do not decorate with black or white frosting because it will bleed. I added the eyes and mouth the day of the party.
