"I always have these ingredients in the pantry. You can use either all purpose flour or whole wheat, quick cook or old fashioned oats, and chunky or smooth peanut butter. When these are in the oven, the house smells so good that my husband would even try them I think. I love to whip these up for the girls (dogs). It's only fair they get special treats now and again :) I also make these around Christmas and give them to my friends with dogs! Great gift for pet owners!!!..."
