This cake is white velvet with chocolate buttercream then covered in white fondant. We gave it cracks in the skull by drawing them in and then painted the fondant with brown food color. The blood is piping gel. Everything on the cake is edible except the spider. I went to the candy store for everything and yes those are fired Larvey on the cake. My friend wanted gross....We had sooo much fun making this cake! It was a hit at the party!!!!!
