My mom found this recipe when I was a little kid, and has been making them ever since. She even switched to this peanut butter cookie base to make her Christmas cookies, Peanut Butter Blossoms. And, as the times have evolved we now use butter instead of margarine, but the cookies turn out just a bit different. I have left margarine in the recipe here just for old-times-sake.
1 C sugar
3/4 C margarine
2 C. flour
2 tsp baking soda
1/2 tsp. salt
1/3 c. peanut butter
6 oz. semi-sweet chocolate chips
Cream margarine and sugar. Add in rest of ingredients one at a time until well blended (may have to use your hands to mix as dough is stiff).
Roll in sugar before baking and use forks to make cross pattern. Do not grease cookies sheet. Bake at 350 for 12-15 minutes.
