01 - Line a muffin tin with paper cupcake liners or parchment squares.
02 - Combine chocolate chips and butter in a large heatproof bowl. Melt together using a microwave in 30-second bursts, stirring between each, until smooth. Alternatively, melt over a double boiler.
03 - Add the crispy rice cereal (and coconut, if using) to the melted chocolate mixture. Stir until evenly coated.
04 - Spoon the mixture evenly into the prepared muffin cups, about 2 tablespoons per cup. Use the back of a spoon to press and create a well in the center of each nest.
05 - Refrigerate the nests for at least 30 minutes, or until completely firm and set.
06 - Once firm, remove the nests from the tin and gently peel away the paper liners.
07 - Fill the center of each nest with jelly beans or candy eggs just before serving.
