Units Scale
  • 2 large eggs
  • 2 tablespoon avocado oil (or melted cooled coconut oil, or light olive oil)
  • 1/4 cup pure maple syrup
  • 1 teaspoon vanilla extract
  • 1 1/2 cups milk
  • 2.25 cups rolled oats
  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon fine sea salt
  • 1 cup diced apple (I used cosmic crisp, but honeycrisp, granny smith – one with a nice crunch is best)


  1. Preheat oven to 375ºF and grease 9×9 baking dish or a 1.5 quart casserole dish (or a similar size).
  2. Whisk Wet Ingredients: In large bowl whisk together eggs, oil, maple syrup, vanilla extract and milk.
  3. Add Dry Ingredients: Add in rolled oats, baking powder, cinnamon and salt.
  4. Gently fold in diced apples and transfer to prepared baking dish. Top with chopped walnuts if you’d like.
  5. Bake for 35-40 minutes or, until top is golden and middle is set. You can serve immediately bowl style, or wait about 20 minutes to serve as squares.
  6. Serve apple baked oatmeal with your favorite toppings, a little extra maple syrup or honey and enjoy!
