Smitten Kitchen. I don't know food blog etiquette yet, so I hope it's not rude to borrow recipes and drool all over my keyboard while doing so.
I had to reduce the cooking time on these a bit, down to 8 minutes. I used the Toll House chocolate chunks, and creamy JIF peanut butter.
These are *pretty* cookies too, since they're little and cute and rolled in sugar, so I'm looking forward to sharing them tomorrow. Here's the link to the recipe: http://smittenkitchen.com/2007/12/peanut-butter-cookies/
Replicating Magnolia goodness in my apartment almost makes up for the fact that I ended up in DC instead of NY after college!
