Thanks for a hit! I was nervous making them b/c of all the comments, but mine turned out so cute! I used a couple of the suggestions people had- real butter vs. margarine and a dark cookie sheet. I also lined the sheets w/ parchment paper. I didn't have sprinkles and used icing to make hearts over the white chocolate drizzle and it was a messy mistake, but other than that, they are a huge hit!
