This is a cake my sister and I did for a little boy's birthday. The rocket ship and the moon are marble cake and the cupcakes are vanilla. All have vanilla buttercream frosting and the moon is also covered in fondant. The stars on top of the cupcakes and on the cake board are fondant. The blue cake board is a foam core board. Inspiration came from a similar cake I saw on Flickr. The mom said the little boy just stared at it and said "Wow".
