After tasting similar cookies at a picnic, we excitedly left with our friend's recipe. We were intrigued by the technique, but determined to eliminate that odd aftertaste which so often results from using Splenda in baked goods. We also wanted the finished cookie to be a bit less dry and crumbly. A few tweaks later, we enjoyed a terrific batch of gluten-free peanut butter cookies which could stand up against the best of traditional-method cookies. These quick cookies freeze well if you want (need) to reserve them for portion control. And, with only 3 tablespoons of real sugar divided across 16 cookies, one (or two!) a day won't wreck your South Beach or diabetic menu plan. We are usually tempted to double the vanilla in any recipe, but here the small amount of vanilla adds a depth of flavor without interfering with the rich peanut taste. Please note that the 5 minute preparation time does NOT include the 30 minutes this dough needs to rest in the refrigerator.
