01 - Line a 12-cup muffin tin with paper liners or lightly grease with nonstick cooking spray to prevent sticking.
02 - Combine chocolate chips and butter in a heatproof bowl. Microwave in 30-second intervals, stirring between each burst, until completely smooth and melted. Alternatively, use a double boiler for gentle heating.
03 - Add crushed cereal to the melted chocolate mixture. Fold gently with a spatula until every piece is evenly coated with the chocolate.
04 - Divide the mixture evenly among the prepared muffin cups. Using the back of a spoon, press down in the center of each to create a deep well, shaping the sides upward to resemble a nest.
05 - Refrigerate the muffin tin for 30 minutes or until the chocolate has completely hardened and the nests hold their shape.
06 - Remove chilled nests from the tin. Place 3-4 jelly beans or candy-coated chocolate eggs in the center well of each nest. Serve immediately or store in an airtight container.
