Mars Bar Crispy Cake

Cut the Mars Bars into small slices and melt with the margarine in a glass bowl over a saucepan of boiling water.

Take off the heat and mix in the Rice Crispies one cup at a time until the mixture is only slightly gooey.

Spoon the mixture into a tray and spread out evenly.

Heat up the milk chocolate in a glass bowl and spoon evenly over the Crispies.

Leave to cool slightly then place in the fridge for a few hours until set.
