Peanut butter biscuits

This another recipe from my Delia Smith baking cookbook, which unfortunately I can't find online so I'm not sure whether I'm allowed to share the recipe :S What do you think?
They are delicious, definitely the nicest peanut butter biscuits I've ever made :) I'll be making more soon, I'm sure!
