I had a jar of all-natural peanut butter that I had bought at a surplus grocery outlet for $1. We had gotten some really awesome natural peanut butters there, but no one liked this particular brand very much and it was just sitting in the cupboard uneaten. So my son and I made dog treats with it. We doubled this recipe so we had plenty for our two dogs and some to give my parents' dog as a gift.
8 oz peanut butter
2 cups flour
1 T baking powder
1 C milk
Roll and cut out into shapes like you would with sugar cookie cutouts. Some people use Dog bone shaped cookie cuttersbut we just used some Christmas shaped ones that we had.
Bake at 350 for 20 minutes on a greased cookie sheet.
