Servings: 6


  • 2 cups rolled old-fashioned oats
  • 1 teaspoon cinnamon
  • 1 teaspoon baking powder
  • ½ teaspoon sea salt
  • 2 cups non-dairy milk I like using unsweetened vanilla almond milk
  • ½ cup unsweetened applesauce
  • ¼ cup maple syrup
  • 1 Tablespoon ground flaxseed
  • 1 Tablespoon coconut oil
  • 1 teaspoon vanilla extract
  • 1 cup diced apple divided
  • ½ cup raisins


  • Preheat oven to 375°F. Spray an 8x8 baking dish with non-stick spray.
  • In a large bowl, mix together rolled oats, cinnamon, baking powder, salt, almond milk, applesauce, maple syrup, flaxseed, coconut oil and vanilla.

  • Bake about 40 minutes or until the center has set and a toothpick comes out clean. Allow baked oatmeal to cool just a bit before serving. Serve with a drizzle of almond butter, almond milk, or maple syrup.

  • Store in the refrigerator in an airtight container for up to 4 days. To reheat the whole baked oatmeal, cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set oven (or toaster oven) to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute.



  • Oats – Rolled oats work best for baked oatmeal and I don’t recommend swapping them for quick oats or steel-cut oats as the liquid ratio and cook time will differ. If you’re looking for a baked oatmeal recipe that’s made with steel-cut oats I suggest checking out this apple baked steel cut oatmeal recipe instead.
  • Milk – Any non-dairy milk will work here. Almond, oat, soy, or even coconut milk can be used depending on your preference.
  • Sweetener – If you're out of maple syrup, you can substitute with honey or agave syrup. Just note that this will slightly alter the flavor profile.
  • Flaxseed – Chia seeds can be a good alternative to flaxseed if you're looking for another source of omega-3 fatty acids. Or you can use 1 egg if you don’t need this recipe to be vegan.
  • Coconut oil – If you prefer not to use coconut oil, you can substitute with another mild-flavored oil like avocado oil or even melted unsalted butter for a non-vegan option. I’ve also made baked oatmeal without coconut oil and it turned out just fine!
  • Raisins – Feel free to swap out the raisins for other dried fruits like cranberries or chopped dried apricots for a different twist. Another good substitute would be nuts like chopped walnuts or pecans.
  • Spices – If you want to add even more spice to this baked apple oatmeal recipe you could add a dash of nutmeg, ginger, allspice and/or apple pie spice.
