Fabulous cookie recipe! I used creamy peanut butter and salted butter because that's what I had on hand. I did add a scant 1/4th teaspoon of salt. I used brown sugar only, 2 cups. I refigerated the dough as directed and had no problem with over spreading. I made these cookies large. My husband who is very picky loved them. Surprise! Surprise!
Delicious! So easy to prepare and very tasty. I followed the recipe almost exactly. I didn't crisp the Prosciutto. I added some slices of yellow pepper for the crunch factor. I used grated Mozzarella which I had on hand. I wolfed it down and my mouth is watering for another. Yummy!
