Mars Bar Cake

Melt the Mars Bars and Butter in a saucepan until smooth.

Stir in the Coco Pops to the melted mixture.

Pour into a lined square tin and press down firmly with the back of a spoon, ensuring the mixture has reached all of the corners.

Melt the Milk Chocolate and pour over the mixture in the tin.

Chill for at least an hour until set.

Cut into squares and serve!
