Icarus's surefire winner for all fund raising events, kids parties etc.
Take 4 mars bars of normal size. Chop up into 1cm chunks, scissors are fabulous for this.
4oz of butter. Melt together, I use a large pan on a low heat, some use a bain de marie other melt in the micro. Use a large bowl/pan.
it will look disgusting. beat it together until it looks like a smooth toffee sauce.
tip in 4 oz of crispies and stir until they are covered. tip into a lined container, tray bake tin or similar and flatten. stck in fridge.
melt choc i use dairy milk tbh, about 1.5 big bars and spread on the top. Stick it back in the fridge until cool.
Lift out and slice it up and mmmmmmmm.
