But if you want your actual cake to be a little more creative, and yet still easy, then here's an idea for you. Buy a heart-shaped cake pan and bake your cake. Once cool, you can simply shave off the pointed end of the heart to make it more rounded and you'll end up with a shape that looks very much like a lily pad. Either frost the cake green or cover it with green fondant. Then decorate the cake with little lilac colored flowers cut out from fondant with a small flower-shaped cookie cutter (see how to make little fondant flowers here). You can then use a Princess and the Frog cake topper as the final decoration.
