I got this idea for a Pac Man Birthday Cake online at “15 cool and cute cupcakes for the ultimate geek”. I started with mini unfrosted chocolate cupcakes. I glued them down on my base with a small dot of hot glue on the bottom of the paper liner so they wouldn’t jostle. I cut all the shapes out of store bought fondant, which I colored with Wilton icing colors (a very concentrated paste).
The fondant rolls out and cuts very easily, like play-dough! I “glued” the shapes on with a simple confectioner’s sugar/milk icing. My 10 year old son and I had a lot of fun assembling this cake for his birthday.
