Your eyes are deceiving you. This may look like a hamburger, but it's really dessert. KinkyKittenHeather made two dozen baked "hamburgers" for a family Fourth of July party. The ingredients are all sweet.
Cupcake bun, brownie "burger," coconut dyed green as lettuce, and red icing as ketchup.
Edit: The cheese is yellow marshmallow fondant.
She promised to report back and let reddit know how the burgers go over with the family. See more pictures at imgur.
