Use toasted angel flake coconut for a realistic-looking nest; fill with jelly beans. For fluffy bunnies, use untoasted macaroon coconut.
Preheat oven to 350 degrees; toast coconut on a rimmed baking sheet, stirring occasionally, for 7 to 10 minutes or until light brown.
Place cooled coconut on a rimmed baking sheet or in shallow bowls. Pipe shapes; cover each completely with coconut.
To make nests, use a 1/2-inch (#11 Ateco) tip; pipe directly onto coconut, making a flat spiral about 3 inches in diameter. Build up the sides by spiraling up the edge of the disk, about 3/4 inch. Fill and cover with coconut, and allow to set a few minutes. Remove excess coconut from the center, and transfer to a parchment-lined airtight container until ready to use, or up to 2 weeks.
