Malteaser Fudge

Lizzie sent me this link after she had made some for me and it was right up my street.  I made it myself once at new year and am about to try it again!

That link no longer seems to work so either try this one on twitter or I'll put the basic details here.

300g chocolate, melted in microwave for 30 seconds. Stir and repeat for 10 seconds until melted.
Mix in 375g condensed milk and 350g of malteasers.
Put in a lined baking tin.
Set in the fridge then cut into pieces.
