My 10 year old nephew loves Despicable Me and the Minions. His request for cake was a Minion!  I used 4 – 8 inch round cakes, stacked, and one domed cake (made in Pyrex bowl) to make the Minion.  I stacked them together and filled in the colors using an image from the movie. The hair, arms, hand and feet are made out of rolled fondant, otherwise everything else is butter cream.
