Do you sell this cake? No, just for fun Share a little about the materials, processes, and techniques used to create this cake I wanted this cake to be a funny cake for my brother's 50th birthday. It is a gravestone in grey and black, but nice bright flowers grow around it. I used the 12 inch square topsy turvy cake pan because the shape was perfect. I used royal icing flowers, but frosted the cake with buttercream. I also used some black spray coloring on the grey icing to make it look old.
