This is an old recipe that faded out of popularity (with some of us). Who knows why because it is genius. These are light & airy, you will not miss the flour; it's not only for those who are gluten intolerant.
1 cup peanut butter (any kind)
1 cup granulated sugar
1 egg
1 tsp. vanilla
1/2 tsp. baking soda
sugar for the top if desired
Mix everything together. You don't need a mixer. Just one bowl. Scoop out tablespoonfuls onto a non-greased baking sheet. (A nice touch is some demerara or turbinado sugar sprinkled on top, after the traditional crosshatching by fork.) Heat the oven to 350F. Bake 11 minutes (times will vary, keep an eye on them). Cool at least 5 minutes before removing to a wire rack - they are fragile until cool.
