Made this one for a 13 yr old's pool party. He wanted chocolated cake with strawberry filling and cream cheese icing Kind of specific for a 13yr old boy, I know. I used piping gel for the water. In the future, I'm going to try to make my own piping gel - the Wilton gel tastes kind of weird when you use more than just a tiny bit. I know it can be scraped off - I just don't like the idea of anyone having to scrape something off my cake because it doesn't taste good. I added the "DIVE IN" on the diving at the last minute. Diving board is a graham cracker covered with cream cheese icing. TFL!
