This recipe is straight out of my treasured second edition Joy of Cooking. Which, of course, I can't find a copy of anywhere to link. I did find this facsimile edition of the original Joy of Cooking, though!
Peanut Butter CookiesMargarine works fine, and I prefer the flavor with butter or margarine. I wisk all the dry ingredients together first. But it's that easy.
1/2 c butter or shortening
1/2 c firmly packed brown sugar
1/2 c granulated sugar
1 cup peanut butter
1/2 tsp salt
1/2 tsp baking soda
1 tsp vanilla
1 to 1 1/2c flour
Preheat oven to 375F. Beat the butter until soft. Gradually add both sugars and blend until creamy. Beat in all remaining ingredients except flour. Add flour, using the larger amount if your peanut butter is oily.
Roll the dough into small balls. Place them on a greased cookie sheet and press flat with a fork dipped in flour, making a criss-cross pattern. Base for 10 to 12 minutes.
