  • Wet ingredients:
  • 1 medium zucchini*
  • 1/2 cup unsweetened applesauce (i love using cinnamon applesauce!)
  • 2 eggs, at room temperature
  • 1 cup unsweetened almond milk
  • 1/4 cup pure maple syrup
  • 1 teaspoon vanilla extract
  • 2 tablespoons melted butter or melted and cooled coconut oil
  • Dry ingredients:
  • 2 cups old fashioned rolled oats, gluten free if desired
  • 1 teaspoon baking powder
  • 1 teaspoon cinnamon
  • ½ teaspoon allspice
  • ½ teaspoon ginger
  • ¼ teaspoon nutmeg
  • ¼ teaspoon salt
  • 1 cup finely diced honeycrisp apples (from 1 medium honeycrisp apple, diced)
  • Optional: 1/4 cup raisins
  • Optional: 1/3 cup finely chopped pecans or walnuts
  • For the cinnamon vanilla glaze:
  • 2 tablespoons vanilla yogurt (or sub dairy free yogurt)
  • 1 tablespoon powdered sugar (or you can sub 1/2 tablespoon maple syrup or honey)
  • 1-2 teaspoons unsweetened almond milk, to thin
  • ¼ teaspoon cinnamon
  • ¼ teaspoon vanilla extract
  • For topping:
  • Optional: Thinly sliced apples


  • Preheat the oven to 350 degrees F. Spray a 8x8 inch baking pan with nonstick cooking spray.
  • *First, measure out 1 heaping cup of shredded zucchini from your medium zucchini, then place shredded zucchini in a paper towel or cheese cloth and squeeze out all of the moisture/water. This is very important!
  • In a medium bowl, mix together the shredded zucchini, applesauce, eggs, almond milk, maple syrup, vanilla, and melted and cooled butter or coconut oil until well combined.
  • Next stir in dry ingredients: oats, baking powder, cinnamon, allspice, ginger, nutmeg and salt; stir well to combine. Fold in diced apples, raisins and pecans/walnuts.
  • Spread out oatmeal in a prepared pan. Add thinly sliced apples on top if you’d like. Bake for 35-40 minutes until edges are slightly golden and center is set.
  • In a small bowl, mix together the greek yogurt, powdered sugar, milk, vanilla and cinnamon; mix to combine. Add more milk if necessary so you can drizzle on top of the oatmeal. Serves 6-8. Enjoy!


Feel free to skip the glaze and just drizzle the baked oatmeal with maple syrup instead; it’s just as delicious!
