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 smooth and fully melted, then remove from heat.
03 - Gently fold the cornflakes into the melted chocolate mixture using a spatula until every piece is evenly coated. Take care not to crush the cereal too much while mixing.
04 - Divide the chocolate-coated cereal evenly among the paper cases, approximately 2 tablespoons per case. 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 to 3 mini chocolate eggs into the center hollow of each nest while the chocolate is still slightly tacky so they adhere well.
06 - Transfer the muffin tin to the refrigerator and chill for at least 30 minutes, or until the chocolate is completely firm and set.
07 - Carefully remove the nests from the tin and peel away the paper cases before serving. Display on a platter for Easter festivities.
