Method
 

Step 1: Mix the Peanut Base
  1. In a mixing bowl, combine peanut butter, egg, olive oil, and water. Stir until smooth and creamy.
Step 2: Add the Dry Ingredients
  1. Add the whole wheat flour (and flaxseed if using).
  2. Mix until a dough forms—slightly firm but not crumbly.
  3. If dry → add a splash of water.
  4. If sticky → add a spoon of flour.
Step 3: Roll Out the Dough
  1. Lightly flour your surface.
  2. Roll dough to ¼ inch thickness for classic crunchy biscuits.
Step 4: Cut Out the Shapes
  1. Use cookie cutters to make fun shapes, or simply cut strips or squares with a knife.
  2. Place on a parchment-lined baking sheet.
Step 5: Bake Until Crunchy
  1. Bake at 350°F (175°C) for 18–22 minutes, or until hard, dry, and lightly golden.
