Ingredients
  

For the Biscuit Dough
  • 2 cups whole wheat flour or oat flour for sensitive stomachs
  • ½ cup natural peanut butter xylitol-free only
  • 1 egg
  • ⅔ cup water add more as needed
  • 1 tbsp olive oil
Optional Add-Ins
  • 1 tbsp ground flaxseed
  • 2 tbsp unsweetened applesauce
  • 1 tbsp honey for extra crisp browning—optional

Equipment

  • Mixing bowl
  • Whisk or spoon
  • Rolling Pin
  • Cookie cutters (bone shapes, circles, etc.)
  • Baking sheet
  • Parchment paper
  • Cooling rack

Method
 

Step 1: Make the Peanut Butter Base
  1. In a mixing bowl, whisk peanut butter, egg, olive oil, and water until smooth.
Step 2: Add the Dry Ingredients
  1. Add whole wheat flour (and flaxseed if using). Mix until a firm dough forms.
  2. If the dough is crumbly, add 1–2 tbsp water.
  3. If too sticky, add a sprinkle of flour.
Step 3: Roll Out the Dough
  1. Lightly flour your surface. Roll dough to about ¼ inch thick for crunchy biscuits.
Step 4: Cut the Treats
  1. Use cookie cutters to cut shapes. Transfer each piece to a parchment-lined baking sheet.
Step 5: Bake Until Crunchy
  1. Bake at 350°F (175°C) for 18–22 minutes, or until the treats are hard and golden.
Step 6: Cool Completely
  1. Let biscuits cool fully on a rack—they firm up even more as they cool.
