I actually heard back from the person in charge of licensing, Erin Dippold, at Wild Brain Entertainment via email. She said that I can do a Yo Gabba Gabba cake for personal use and even encourage fans to post pics on their facebook page. It would be okay for me to post pics on my business page as representation of my work/talent... However, she couldn't grant permission for me to market and sell the cake. Good thing I called back and asked for written permission! Thanks again Jason! The person I spoke to over the phone the first time did NOT have the authority to grant permission Lesson learned on my part, I guess!
It's all for the best anyway. My cake was a bit of a disaster. I traveled to southern California where we were having my son's party. My original plan was to make ganache since I knew it would be quite warm and the party was going to be outside at the park. I did not have enough time to have my ganache set up (I even had my sister bake the cake before I got there), so I made buttercream instead. I was to make the cake at my sister's house. We didn't learn until we got there that her AC was out And it was hot! Yeah. By the time we brought the cake to the park, my bc was kind of mush. It was beautiful until I started the decorating. The fondant went on great, but the bc started softening soon after. My edges were super round (they were nice and sharp when I started) and the bc just kind of melted towards the bottom of the cake making a bulge all around the bottom edge Luckily, all the kids seemed impressed still, including my son, which is what mattered the most that day. I will not be posting pictures though
