Rainbow Hello Kitty cake. I coated the cake with a layer of buttercream frosting. Then I enlarged a coloring page on my printer. I transferred the image to the cake by poking holes with a toothpick. I outlined Hello Kitty with pre-made black icing, then went to work piping 1001 stars with tinted icing. The neon food coloring box had every color I needed except yellow. I forgot the whiskers... but it was my first cake, so all in all it turned out good.
