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 constantly until completely smooth and fully melted, then remove from heat.
03 - Gently fold the cornflakes into the melted chocolate mixture using a spatula, ensuring every piece is evenly coated without crushing the cereal.
04 - Divide the chocolate-coated cereal evenly among the prepared liners. Press gently in the center of each portion with the back of a spoon to create a shallow nest shape.
05 - Place 3 to 4 mini chocolate eggs in the center of each nest while the chocolate is still slightly sticky.
06 - Refrigerate the nests for at least 30 minutes or until completely firm and set before serving.
