Both are vanilla cakes. the top tier made of 4 of the rainbow colours filled with cream cheese icing and the lower tier is white with chocolate filling. I made this cake for my daughter's 4th birthday. I'm not professional but I love making special cakes for my kids, as best as I can :-) I made 6 cakes for each of the rainbow colours. But I had to leave the blue and the purple out because I couldn't roll enough fondant to cover it. I should have made the layers thinner. But well, this is how we learn: from our mistakes :-) And the rainbow, was a challenge and was falling apart on the way to the venue :-( Despite all my mistakes, the cake was a hit inside out at the birthday party and the parents were asking if I take orders. They made my day :-)
