I used two 9×13 cakes stacked, to make this Guinea Pig Cake, then just rounded out the edges and tapered the face a bit. I did my first coat of frosting (the crumb coat) with a really light frosting that I whipped up as much as I could to try to help prevent the cake from pulling up.
I let that sit overnight and then did the final coat the next day. I texturized with a fork on the body and used a tip for the white frosting. The ears where tootsie rolls, warmed in the microwave for like 12 seconds and then shaped. That’s it, and it fed a lot of people!
