Separate 4 Mini Oreos and cut them in half to make wings.
Push two "wings" into either side of 8 Mini doughnuts.
Divide the 16 Edible eyes into the chocolate of the doughnut.
Use two of the 16 Sprinkles pushed into the doughnut hole to form fangs.
Notes
Make a little cut in the side of the doughnuts, as this makes it easier to put the wings in, without breaking the Oreos.
You can make these extra fancy by spraying them with edible glitter. I mean, you don't often find bats covered in glitter, but I think all rules have gone out the window here.
