I'm not ready to call this a real recipe yet, just an experiment. I'll update you when I finalize it!
I added a blob of peanut butter (Skippy chunky because that's what we had) about a heaping tablespoon full. My guess is that, as much of a purist and naturalist as I am, I wouldn't want to use natural style peanut butter where you have to mix the oil together. I put the dough back on the bread hook in the KitchenAid and kneaded away, adding flour until the dough seemed healthy and like regular dough.
Add 1/3 c. chocolate chips by hand. We use Trader Joe's chocolate chips because they're pareve (non-dairy), and they're way more delicious than any others I've tried!
