I have been searching for a very long time to find a really good PB cookie recipe. I have tried many, many recipes. This is by far the best. The taste and texture are exactly what I have been searching for. I was making these one night, it was getting pretty late, and I fell asleep while they were cooling, before I could put them in an air-tight container. The next morning when I woke up I was really upset, because I thought I had ruined them by leaving them sitting out all night. To my great surprise and relief, they were not dried out at all. Still very moist and chewy. I will be using this recipe, hopefully, for many years to come. Thank you P.L. Weiss for submitting it.
