Method
 

Step 1: Prepare the Apple
  1. Peel and finely grate the apple. Squeeze gently to remove excess moisture so the biscuits bake crisp.
Step 2: Mix the Wet Base
  1. In a bowl, combine grated apple, peanut butter, egg, and optional applesauce. Stir until blended.
Step 3: Add the Dry Ingredients
  1. Add oat flour, whole wheat flour, and flaxseed if using.
  2. Mix until a firm dough forms.
  3. If too dry → add a little water.
  4. If too sticky → add a sprinkle of flour.
Step 4: Roll & Cut
  1. Lightly flour your surface and roll dough to ¼ inch thickness.
  2. Use cookie cutters (bones, hearts, circles) to cut shapes.
  3. Place onto a parchment-lined baking sheet.
Step 5: Bake Until Crunchy
  1. Bake at 350°F (175°C) for 18–22 minutes, or until golden and firm.
  2. For extra crunch, turn the oven off and let biscuits sit inside for 30–60 minutes.
Step 6: Cool Completely
  1. Cool on a rack—crunch develops fully as they cool.
