P.S. The treats are made of human food, BUT ... they taste horrific. (I know, I tried some. Also my mom tried some, but I warned her. To all those parents out there, you should listen to your kids!)
Here's the dog treats in the pan:
Here's Maggie trying one:

RECIPE
2 cups whole wheat flour
1 tablespoon baking powder
1 cup peanut butter (chunky or smooth)
1 cup milk
Instructions
Preheat oven to 375 degrees F. In a bowl, combine flour and baking powder. In another bowl, mix peanut butter and milk, and then add to dry ingredients and mix well. Place dough on a lightly floured surface and knead. Roll dough to 1/4 inch thickness and use a cookie cutter to cut out shapes. Bake for 20 minutes on a greased baking sheet until lightly browned. Cool on a rack, then store in an airtight container.
Note, I found the cookies burn easily so watch them.
Also note ... Maggie loved her treats!
