Crunchy Peanut Butter Squares

I found this recipe in a childrens section in one of Nigella's books and i couldn't resist making them! However I altered mine slightly by using crunchy peanut butter and slightly different quantities as i like abit more crunch in mine. And believe me when i say you only need tiny squares!

For the peanut butter base:

150g crunchy peanut butter
25g butter
100g icing sugar
25g light brown muscavado sugar

For the chocolate topping:

100g plain chocolate
70g milk chocolate
25g butter

Method:

Put all the ingredients for the base i a bowl and mix together- it will be pretty lumpy but thats ok! Then press it down into a small lined brownie tin making it as compact as possible(i find it easiest to use my fingers to do this). For the top melt all the ingredients together then spread onto the base. Put it in the fridge until the chocolate is set then cut into squares! It makes roughly 20 small squares.
