Mrs Cakescakescakes malteser slice

It's the last day of primary school for A today. He wanted to take a gift into his teacher and TA so we decided to make malteser slices for them. I got the recipe from the brilliant blipper Cakescakescakes

I did change the recipe a little as I ran out of maltesers (I don't know where that half packet disappeared to....) so had to improvise with revels (don't know where the toffee ones disappeared to either?).
