Soften margarine and add other two ingredients. Mix for 2 minutes. Place cookies on cookie sheet and bake at 350 degrees until golden brown {about 6 minutes}.
I got a recipe for the world's easiest peanut butter cookies a few years back out of a Kraft Food and Family magazine.
I love this recipe because it is super easy, very tasty, and I always have all the ingredients on hand (they are also gluten free).
Peanut Butter Cookies
1 cup creamy peanut butter
1/2 cup sugar
1 egg
Preheat oven to 325ºF. Mix peanut butter, sugar, and egg until well blended. Refrigerate dough for 30 minutes. Roll dough into 18 (I never get more than 14) balls. Place, 2 inches apart, on ungreased baking sheet. Flatten each ball, in a criss-cross pattern with a fork.
Bake 18 to 20 minutes or until lightly browned. Let cool on wire rack.
*For a fun twist: After the cookies have cooled, dip each end into melted chocolate, then into finely chopped peanuts and refrigerate until the chocolate hardens.
*For a more healthy twist try using Blue Agave nectar or Stevia instead of the sugar.
