Ingredients and substitutions

Rolled Oats: To make this recipe gluten-free, you need to use certified gluten-free oats. If you don’t need it to be gluten-free, you can use any brand. My favorite gluten-free brand is One Degree Sprouted Oats, and if you live near a Costco, I’ve seen them there at a very low price.
Milk: Use any nut milk like almond or cashew. You can also use oat milk or coconut milk. Regular dairy milk can be used if you don’t need this to be dairy-free.
Sweetener: You have a lot of options when it comes to a sweetener: granulated sugar, brown sugar, coconut sugar, maple syrup, or honey.
Dairy-Free Butter: For dairy-free options, you can use your favorite dairy-free butter, coconut oil, butter-flavored coconut oil, or ghee. Use regular dairy butter if dairy isn’t a problem.
Eggs: If you want to make this egg-free, you can use two flax eggs, half of a cup of applesauce, or a mashed banana.
Baking Powder: The baking powder helps the oatmeal to fluff up and not bake flat.
Vanilla Extract: Vanilla adds a delicious flavor.
Salt: Real Salt or Himalayan Salt.
Instructions
Preheat oven to 350°. Grease a 9″ x 13″ or 9″ baking dish with cooking spray.

In a large bowl, add the melted buttery spread and all of the rest of the ingredients and stir together until combined. Pour the oat mixture into the prepared baking dish.

Bake the 9″ x 13″ baking dish for 30 minutes or, if using a 9″ baking dish, bake it for 45 minutes. Serve warm.

Optional toppings:
This baked oatmeal is yummy as is, but if you want to put any toppings on it, here are a few delicious options:
- Cut up fruit like strawberries or bananas
- Blueberries or raspberries
- A drizzle of maple syrup or honey
- Sprinkle the top with powdered sugar or brown sugar.

Storage and freezing
Baked oatmeal can be stored covered in the refrigerator for 4-5 days. To freeze, freeze in single-serving sizes so you can pull out a serving when you need it. Let it thaw overnight in the refrigerator, and then reheat it in a skillet over low heat or the microwave.
