I got this from my sister in law who has celiac's disease. She has added chocolate chips and other gluten-free treats to them!
The recipe clearly states to used processed peanut butter like Skippy or Jif.
1 cup brown sugar
1 cup peanut butter
2 eggs
1 1/4 tsp baking soda
1 tsp vanilla
Mix together. Drop by rounded spoonfuls onto ungreased cookie sheet. Bake at 350 for 8-11 minutes.
