The bottom is a 12x12 square yellow cake. The top is a 9" round yellow cake.
I covered it in buttercream fondant and used gumpaste to decorate the cake. It has daisies on top. The center of the daisies I used gumpaste dyed gumpaste ball of each color and then I used "gum glue/adhesive" which is just a little water and some small little chunks of gumpaste mixed together. It takes about 20 minutes for the gumpaste chunks to dissolved in the water. So I used the gumpaste adhesive and a paint brush to dab a little bit onto the centers of the daisies and then dipped it into colored sugar crystals.
