I did this for my daughter's 5 yr b-day. She loves this movie and character. I took the barbie cake pan that had flowers in the background and iced white over the flower part. Then did 2 shades of pink. using a big star tip to do the middle of her dress. Over the dark pink part of her dress I used the Wilton color sparkle things in dark pink. & white sparkle/sprinkles over the white portion of the cake. I did some star tip over the barbie lay-on since she had a purple top. Roses are royal icing.
