I took these to a family Christmas party. I thought they were super adorable, and so I was bummed when I overheard someone talking, disappointedly, about how they looked like they had glitter on them. They are sprinkles!
All I did was make a box of brownies and once they cooled I frosted them (with canned frosting) and then covered with clear sprinkles which you can't really see in this picture, but oh well. I also took some tree shaped pretzels, which I found at Sam's Club, and dipped them in white chocolate that I melted and added green food coloring to. They also got a generous dose of sprinkles. Stick the pretzels into the brownies and voila! You have a cute little brownie-pretzel forest.
