Ingredients

Scale

Wet Ingredients

  • ½ cup (128g) natural drippy peanut butter (creamy or chunky)
  • 1 tablespoon pure maple syrup or honey
  • 1 large egg, slightly beaten
  • 1 teaspoon vanilla extract
  • 1⅓ cups (320g) unsweetened vanilla almond milk (or any milk)

Dry Ingredients

  • 1½ cups (143g) old fashioned rolled oats, gluten free if desired
  • ½ teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon nutmeg
  • ¼ teaspoon salt

Add-ins

  • 1 cup shredded zucchini, squeezed of excess moisture
  • ¼ cup (45g) mini chocolate chips, plus 2 tablespoons for sprinkling on top


Instructions

  1. Preheat and prepare pan: Preheat your oven to 350 degrees F (175 degrees C). Grease an 8×8 inch baking pan with coconut oil or spray generously with nonstick cooking spray to prevent sticking.
  2. Mix wet ingredients: In a large bowl, combine the peanut butter, maple syrup, beaten egg, vanilla extract, and almond milk. Whisk thoroughly until smooth and free of large peanut butter lumps.
  3. Add dry ingredients: Fold in the oats, baking powder, cinnamon, nutmeg, and salt into the wet mixture until evenly combined.
  4. Incorporate zucchini and chocolate chips: Gently fold in the shredded zucchini (make sure it’s well squeezed of excess moisture) and the ¼ cup of mini chocolate chips, distributing them evenly.
  5. Bake the oatmeal: Pour the batter into the prepared baking pan, spreading it out evenly. Sprinkle the remaining 2 tablespoons of mini chocolate chips on top. Bake for 30-35 minutes until the top is lightly golden and the oatmeal is set.
  6. Cool and serve: Allow the baked oatmeal to cool for a few minutes before cutting into 6 servings. Enjoy warm with a splash of almond milk or an extra dollop of peanut butter if desired.
