8 oz of Butter.
8 oz of Sugar. (I used half brown and half white)
8 oz of Digestive Biscuits (crushed)
1 tin Condensed Milk (395 gms)
8 oz melted Milk Chocolate (I had more 'cos wanted a thick layer on top)
How to make..
Line a Swiss roll tin with foil and crush the biscuits, set a side.
Melt the butter, milk and sugar in a saucepan. Bring to the boil and continue boiling for 3 - 5 minutes. Add in the crushed biscuits and stir. Melt the chocolate over simmering water in another saucepan. Pour the milk/biscuit mixture in to the prepared tin and level out with a spatula. Then pour the melted chocolate over the mix in tin and again, level out. Decorate with sprinkles or coarsely grated chocolate. Chill in the fridge. When chilled, remove from pan and slice to your desired size. Stores well in the fridge for a few days in a covered container. I bet you don't just make this the once.
Next time I shall try different biscuits, like ginger snaps maybe, and change the chocolate from milk to dark.
