I first ran across this recipe a few years ago, before I cared about having gluten or milk in my foods. It was on the side of a Kraft peanut butter jar, so you know it wasn't in my house; we generally have the 'only peanuts' kind of pb. (Although I have heard a rumour that Kraft has come out with this product...) These cookies are perfect for children to make on their own. There are only a few ingredients, and no rolling pins or cookie cutters are necessary!
1c peanut butter
1tsp baking powder
Preheat oven at 350
Mix well; roll into balls; place on ungreased baking sheet and flatten with a fork, then bake for 10 minutes.
