Old-fashioned oats, real maple syrup, and fresh berries combine to make a delicious baked oatmeal. You can even start it the night before for an easy breakfast!
Preheat the oven to 350 degrees F and spray a 9×9 square baking dish or pan with cooking spray.
In a large mixing bowl, whisk together the milk, eggs, maple syrup, brown sugar, butter, baking powder, vanilla extract, cinnamon, and salt until well combined.
Sprinkle the oats and berries into the wet ingredients and gently stir to combine. Do not over mix.
Add the oat mixture to the prepared baking pan.
Bake for about 35 minutes or until the center looks nearly set. If you want a drier result, bake until the center looks totally set, about 40-45 minutes.
Notes
How to StoreBaked oatmeal can be stored in the refrigerator for up to 4-5 days in an airtight container.Make Ahead InstructionsIf you want to prepare this overnight and bake the next morning, I recommend using steel cut oats instead of old-fashioned oats.If you use old-fashioned oats and let this sit overnight, your oats will be softer and more cake-like rather than having a normal oatmeal consistency. But this is fine as long as you are okay with having a softer and less-defined texture.SubstitutionsYou may use non-dairy milk in place of the milk.If you want to use a 9x13 pan, by increase the recipe ingredients by 1.5 times.You can replace fresh berries with frozen. If using frozen berries, just make sure to not thaw them or over stir them. Otherwise, they will bleed into the oatmeal more.Replace the butter with coconut oil.The sweetness level can be easily changed by adding more or less maple syrup and brown sugar. I wouldn’t take away more than a few tablespoons of each or add more than a tablespoon or two of each.While old-fashioned oats give the best results, you can also use quick oats if you are okay with the final results being a bit softer and less well-defined.
