Use any cake recipe you choose, as long as it isn't too crumby or light because it won't hold up to the heavy fondant. Color fondant or use pre-colored fondant. You can make the colors several days ahead of time and store in the fridge in a ziplock bag. I prefer mixing mine with Wilton® color gels. Apply a generous coat of buttercream frosting to the layers. Pre-cut shapes ahead of time or cut as you go in step 2. For this cake I made 3 different flavors for each layer. To create the melting/topsy turvy look, cut circles lopsided and cut layers so that the layer above sits INTO the layer below.
You can use boxed fondant, but I make my own marshmallow fondant and it is sooooo much better. Apply fondant as usual, smoothing out as best you can, then affix shapes with a tiny bit of water on a clean paintbrush. Careful not to use too much water because BLACK WILL RUN.
Finish off design and hide imperfections by rolling balls to cover edges. To make fondant SHINE, very lightly brush entire surface with vodka and a clean paintbrush. Again - be careful - BLACK WILL RUN.
**I've been asked a lot - what kind of animal print is that on the bottom layer? My answer is - I have no idea.... just go with it.** :)
