01 - Line a 12-hole muffin tin with paper cupcake cases to prevent sticking and ensure easy removal.
02 - Set a heatproof bowl over a saucepan of simmering water to create a double boiler. Add the milk chocolate, dark chocolate, butter, and golden syrup. Stir continuously until completely melted and smooth, then remove from heat.
03 - Gently fold the cornflakes into the melted chocolate mixture until evenly coated. Take care not to crush the flakes while mixing.
04 - Divide the chocolate-coated cornflakes evenly among the prepared paper cases. Press lightly with the back of a spoon to create a nest shape, forming a slight hollow in the center of each.
05 - Place 2-3 mini chocolate eggs in the center hollow of each nest while the mixture is still slightly soft so they adhere properly.
06 - Refrigerate the nests for at least 30 minutes, or until completely firm and set.
07 - Remove the nests from the muffin tin and peel away the paper cases before serving.
