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