Preheat the oven to 350º Fahrenheit degrees. This dog biscuit recipe mixes together easily so there's no need for a stand mixer.
In a large bowl, whisk together the whole wheat flour and baking powder. Add the peanut butter, milk, and molasses; mix until well combined. 2 cups whole wheat flour, 2 teaspoons baking powder, 1 cup all-natural smooth peanut butter, 1 cup whole milk, 1 tablespoon molasses
Use a rolling pin to roll the dough out between two sheets of parchment paper (or waxed paper) to ¼ inch thickness.
Cut the dough into small shapes with a cookie cutter. Transfer each dog treat to an ungreased baking sheet, leaving ½ inch of space between each treat.
Bake for 15-17 minutes. The treats may still be slightly soft in the center but should be fairly dry and hardened around the edges.
Remove the dog treats from the oven and cool completely to room temperature before storing.
Notes
Recipe Tips

For crunchier homemade treats, bake slightly longer or let them dry in the oven
Storage: Store at room temperature for up to 1 week in airtight container. Store in the fridge for up to 2 weeks. Or store in the freezer for up to 3 months. If they feel soft after storing, you can re-bake them for a few minutes to crisp them up again.
