I did this cake this morning for a little Fiesta this evening.
It's a 12" square on the bottom and an 8" square on top. The bottom has a lime glaze in the middle and the top has lemon buttercream in the middle. The stripes and maracas are fondant.
I made this cake for my dad's birthday. The chess board is a peanut butter cake with chocolate peanut truffle filling and chocolate buttercream. The white squares on the board are fondant and the pieces are dark and white chocolate, made using a candy mold. (which I have, if someone local wants to borrow it)
