- 3 cups whole wheat flour plus more for surface dusting
- 2 cups old-fashioned oats
- 1/4 cup wheat germ

- 1 large egg
- 1/2 cup peanut butter
- Rolling pin
- 3-inch bone-shaped cookie cutter
Instructions
Preheat the oven to 275 degrees F and lower the top rack to the lower third of the oven. Cut a piece of parchment paper to fit the bottom of a cookie sheet.
Combine 3 cups whole-wheat flour, 2 cups old-fashioned oats, 1/4 cup wheat germ and 1/4 cup nonfat powdered milk in a large mixing bowl with a wooden spoon. Add 1/2 tsp. garlic powder to the dry mixture.
Blend 1 large egg, 1 1/4 cups of water and 1/2 cup creamy peanut butter in a blender or food processor until smooth. Add the wet mixture to the mixing bowl with the dry combination and stir until completely combined.
Sprinkle your work surface with flour and roll the mixture to a 1/2-inch thickness with a rolling pin. Dip a 3-inch bone-shaped cookie cutter into flour and press over the rolled-out mixture. Place the bone-shaped mixture onto the lined cookie sheet.
Bunch up the scrap dough, reroll and press more bone-shaped biscuits. Bake the dough at 275 degrees F for 90 minutes, or up to three hours for drier biscuits.
Store the biscuits in an airtight container, but leave the lid propped a bit for three days to ensure that the dog biscuits are completely dried out.
