In a mixing bowl, combine the peanut butter and semi-sweet chocolate. Microwave in 30-second intervals, stirring after each, until the mixture is smooth and creamy.
Add the shredded wheat cereal to the melted chocolate mixture. Gently fold until every piece is thoroughly coated in chocolatey goodness.
Line your cupcake pan with cupcake liners. Spoon a heaping tablespoon of the chocolate-wheat mixture into each liner. Using the back of the spoon, press down the mixture to create a well in the center, forming a nest shape. (Don’t stress about perfection—nature’s nests are rustic, and yours can be too!)
Place the cupcake pan in the freezer for about 15 minutes, allowing the nests to firm up.
While the nests harden, add a few drops of green food dye to a resealable plastic bag. Toss in the shredded coconut, seal the bag, and shake until the coconut turns a vibrant green. This will be the "grass" for your nests.
Once the chocolate nests are firm, remove them from the cupcake liners. Sprinkle a little of the green coconut “grass” into each nest.
Finish by placing three mini Cadbury eggs (or your candy of choice) on top.
