I got this idea from Bakerella, but don't click that link-- her flowers are all perfect and I don't wish to suffer by comparison. :) I dedicate this post to a friend who, when asked if she prefers flowers or chocolate, says she prefers flowers made of chocolate.
First, little dots of yellow chocolate.
Outline the petals in chocolate chocolate.
Fill them in with red chocolate.
Turn them over and you have a cute chocolate bouquet. You might think the uneven sizes and shapes are because I'm unskilled, but actually I was being whimsical. :)
