Step 6: Decorate the Cake
Once the cake has been coated, start piling on a thick layer of frosting, Use this to smooth out the shape of your final peep, and build out the beak and the tail.
Coat the cake with a thick dusting of the yellow sanding sugar. The only way I was able to get it on the undersides of the beak and tail was to sort of throw the sugar up and at it. It was pretty fun, if not terribly effective.
For the eyes, I melted some chocolate and poured little disks. If you have chocolate wafers, use those instead.
Remove the strips of waxed paper and serve.
