The Last Peanut Butter Cookies Recipe You'll Ever Try

Cream peanut butter and margarine, add sugars and mix well.
Add eggs and mix until creamy.
Add remaining ingredients.
Chill for one hour-I usually skip this step and chill between batches.
Drop by teaspoonful onto cookie sheets- do not flatten.
Bake at 325°F for 15 minutes.
Cool on cookie sheets for about 5 minutes then transfer onto newspaper- the newspaper soaks up extra grease so the cookies don't become crumbly, little trick I learned from my MIL- this is also optional.
Edited to add - Immediately after the cookies are completely cooled I always transfer them to an airtight container. Several posters have mentioned the cookies get hard if you leave them out. I have never had that problem - these cookies have always stayed soft and moist if they are stored in an airtight container.
