Lower fat cookie where prunes replace some of the butter. My children actually prefer these to regular chocolate chip cookies. I always have a batch of these in the freezer for a quick snack. If you want to use white flour use 2 1/4 cups. Be careful how many you eat they can be dangerous!
These are a homemade version of Reese Peanut Butter cups by Nigella Lawson. They got me through my 10 years in England where I couldn't buy the Reese version. Now I think the whole family prefer these.
