According to the TWD rules, we are not supposed to post any recipes. That way, we encourage people to buy the book, Baking: From My Home to Yours by Dorie Greenspan. I encourage you to check out the website and look at the other baker's blogs. Also, you can find the recipe on Stefany's website, if you must. And, I think you should.
I basically followed the directions for these. I used chunky peanut butter and halved the recipe. I also chilled the dough for about 24 hours. I've read that for some people, this didn't work well. However, mine turned out great. I also made my cookies a bit larger, hence the Jumbo added to the title. That left me with about 12 big cookies. Perfect for ice cream sammiches, which I plan on making right now!
