Heat oven to 325 degrees F.
Mix contents of jar with 1/2 cup melted margarine, 2 teaspoons vanilla extract and 2 large eggs. Blend well. The dough will be very stiff. Drop by spoonsful onto ungreased foil on a cookie sheet. Bake for 12 minutes. (There is a reason for the foil. When baked, cookies are too soft to move until they set a few minutes. Using foil lets you take off one sheet and bake the next.) Let cool.
