There's a lot happening on this sweet sixteen cake. Two layers of Devil's Food chocolate cake with buttercream icing are covered in blue and green polka dots made of white chocolate - yummy and good looking! Edible stars and curlicues are the perfect backdrop for a cute quilted purse with a beaded handle. (There's pound cake and buttercream under the fondant.) But for me, the highlight of this festive blue and green cake is the little silver monogrammed buckle.
