My mom and I made this swimming pool cake for a “double birthday bash” for my two little boys. We used an 11 x 15 pan for the base, iced it with white icing, and made everything else out of fondant/gum paste. The cake and characters were modeled after the invitation so it tied in with the theme of the pool party really well.
We used pre-colored fondant for most of the pieces, which we made the day before the party. For the little boys and rocks we used white fondant tinted with brown. For the water we cut a template from parchment, placed it over the cake and sprayed the icing with blue. The slide was part of a Dora play set that my dad cut down so we just had the slide. The umbrellas were wooden pieces purchased at Hobby Lobby.
We had a great time experimenting with the fondant. The fondant pieces were placed on the cake at the party.
