Grandma Nell's Whirlygig Cookies

Due to the high demand, here is the great cookie recipe! It makes about 3 dozen cookies...unless you like the dough as much as I do... :)

Cream together:
1/2 cup shortening
1/2 white sugar
1/2 brown sugar
1/2 cup creamy peanut butter
Add to mixture:
1 egg
1 1/4 cup flour
1/2 t baking soda
1/2 t salt
Using two sheets of waxed paper, roll the dough into an oblong shape about 1/4 inch thick. Melt a package of chocolate chips and spread it evenly over the dough. Roll the dough up lengthwise, like a jelly roll and wrap the roll in waxed paper. Chill. Slice and place on cookie sheets (they can be close together- they won't get much bigger as they cook) and bake at 350 degrees until the cookies are light brown, about 7-9 minutes. Allow to cool for 3 minutes before removing from the sheets.
