01 - Line a muffin tin with paper cupcake liners or cut parchment paper into squares and press into each cup.
02 - Combine chocolate chips and butter in a large heatproof bowl. Microwave in 30-second intervals, stirring thoroughly between each burst, until completely smooth and melted. Alternatively, melt over a double boiler, stirring constantly.
03 - Pour the crispy rice cereal into the melted chocolate mixture. Add shredded coconut if using. Stir gently but thoroughly until all cereal pieces are evenly coated with chocolate.
04 - Spoon approximately 2 tablespoons of the chocolate-coated cereal into each prepared muffin cup. Using the back of a spoon, press the mixture around the edges to create a well in the center, forming a nest shape.
05 - Refrigerate the muffin tin for at least 30 minutes, or until the chocolate is completely firm and the nests hold their shape.
06 - Once set, carefully lift the nests from the muffin tin. Gently peel away the paper liners or parchment, taking care not to break the delicate nests.
07 - Fill the center well of each nest with a small handful of colorful jelly beans or candy-coated chocolate eggs. Arrange them naturally so they look like eggs sitting in a nest.
