Cut 6 of the Creme Eggs into small chunks then cut the other 4 in half. Set aside for now.
Break the chocolate into pieces and add it to a heatproof bowl with the condensed milk.
Gently heat in a double boiler (or in 20-second bursts in the microwave) until the chocolate has melted and the mixture is thick and glossy.
Stir in the Creme Egg chunks then transfer the fudge mixture to your lined tin. Gently press it into place using a rubber spatula or the back of a spoon.
Top with the Creme Egg halves and gently press them in to help them stick.
Refrigerate for two hours until firm. Remove the fudge from the tin, cut into squares and enjoy.
