I would like to make a sitting Spongebob cake for an order next Friday (like the photo), but it has to be a buttercream finish. It’s so tall and narrow I’m not sure how I would deliver it 30 minutes away without messing up the finish. If it was fondant then I could support it with my hands, but the b/c is throwing a monkey wrench in my plans, lol. I feel like it would topple over if I wasn’t holding it up. Any ideas would be greatly appreciated.
