**The original recipe said to melt the peanut butter in the microwave. I didn't do it and my cookies were just fine. I also did not weigh the spelt flour, but I did stir it well before measuring. For the peanut butter, I used Jif Natural and am glad I did because the cookies needed the sweetness from the peanut butter. Spelt flour comes in dark and light. I used light spelt flour from the bin at Whole Foods. And finally, I put the cookies in the refrigerator to re-solidify the chips after they'd cooled slightly because I wanted them to be firm.
