It's not proper Christmas unless you have cookies. I had some problems (big surprise) with these suckers — they ended up without much of a peanut butter taste to them. But then I came across an odd recipe that used no flour at all — just one cup of creamy peanut butter, one cup of white sugar, one egg, one teaspoon of baking soda, and half a teaspoon of vanilla extract. I added a touch of pre-ground cinnamon this time around, and that seemed to work very nicely. Not enough to really be noticable (just like the vanilla extract — it seems to just enhance the overall flavor of the cookie, even though you can't actually taste the vanilla itself.)
Aw, damn, I forgot to add a pinch of salt! Argh. That's the problem when I think I've mastered a recipe, I sometimes get careless. Oh well, they still taste good.
