Instructions

1. Place an oven rack in the center of the oven. Preheat the oven to 375°F. Spray a heavy baking sheet with vegetable oil cooking spray or line with a silicon baking mat. Set aside.
2. In a large bowl, combine the flour, oats, and baking powder. Stir in the peanut butter and broth until the mixture forms a crumbly dough. Press the dough together to form a ball.
3. On a lightly floured work surface, knead the dough for 30 seconds until smooth. Roll out the dough into a 10-inch circle, about 1/2 inch thick. Using the cookie cutter, cut out bone shapes and place on the prepared baking sheet (any scraps of dough can be formed into a ball and re-rolled). Sprinkle with the Parmesan cheese.
4. Bake for 20 minutes, until light golden. Transfer to a wire rack and cool completely. Store in an airtight container for up to 1 week.
