How to Make It
Smear the butter on the bread.
Pour lot of nonpareil rainbow sprinkles into a shallow bowl. Lay the bread, butter side down, in the sprinkles and press gently on the bread to make sure as many sprinkles as possible adhere to the butter. Leave out the sprinkle bowl if you plan to make another slice of fairy bread (you know you will), then pour the sprinkles back into their container. If you're shooting video, however, you'll want to sprinkle the nonpareils over the buttered bread, because obviously that looks much better.
