01 - Line a 12-cup muffin tin with paper cupcake liners and set aside.
02 - Place a heatproof bowl over a pan of simmering water. Add milk chocolate, butter, and golden syrup. Stir continuously until completely smooth and melted. Remove from heat.
03 - Gently fold cornflakes into the melted chocolate mixture using a spatula, ensuring all cereal pieces are evenly coated without crushing them.
04 - Spoon chocolate-coated cereal evenly into prepared liners. Press gently in the center of each to create a distinct nest shape with raised edges.
05 - Place 3 to 4 mini chocolate eggs in the center indentation of each nest while still slightly sticky.
06 - Refrigerate for at least 30 minutes or until completely firm and set before serving.
