Taste the rainbow!

Anyone who knows me will know that I adore baking and decorating cakes, so when my niece's 6th birthday was coming up, of course I offered to bake her cake!  I really have no idea what she is into right now because every time I ask her she gives me a different answer, so I asked her what her favorite color is.  She told me her favorite is light purple, but then later she came up to me and whispered that she really likes all the colors in the whole entire rainbow.  Well, of course I had to make a rainbow cake for her!  Now, I love for cakes to have a little bit of a surprise factor, and this one is no exception!  I made several 8" round cakes and cut them in halves so they would sit in a rainbow arch shape on the cake board.  I hollowed out the middle 3 layers and stuffed them full of skittles!  Then I put the outer layer on and sealed it up, iced it like a rainbow, added some little cake ball clouds and threw on some gold coins for the gold at the end of the rainbow.  Voila!  Nobody knows what is inside until it gets cut open when they get to "See the rainbow, Taste the rainbow" (get it, skittles reference!)
