This cake was made out of buttercream icing, teddy grahams, lifesavers gummies, pretzels, and fruit rollups. And yes you see a can of store brought icing. However, that was bought before I starting making my own chocolate buttercream. (Which is SOOO much better than the store bought)
For this cake, I used a 9x13 pan and carved Nemo. I used the cover of the movie as a template for the decorations.
