Ingredients

  • 3 cups old fashioned rolled oats
  • 2 teaspoons baking soda
  • 1 teaspoon cinnamon
  • teaspoon sea salt
  • 2 eggs lightly beaten
  • ½ cup pure maple syrup
  • 1 teaspoon vanilla extract
  • 1.5 cups milk
  • 1 pint blueberries

Instructions

  • Preheat oven to 350°F. In a medium sized bowl, whisk your dry ingredients together (oats, baking soda, cinnamon, and sea salt). Mix.
  • In another bowl, combine 2 eggs, lightly beaten, maple syrup, vanilla extract and milk. I used whole milk but you can use whatever you have on hand. Whisk together and add to your dry ingredients.
  • Pour the wet ingredients over the dry ingredients and mix using a spoon or spatula. Fold the blueberries into the batter taking care to be gentle (no blueberry smushing here, we want these intact!).
  • Grease a 9x9 baking pan. Pour in the oatmeal mixture into your prepared baking dish and spread evenly.
  • Bake for 35-40 minutes until the center is set. Allow to cool for 15-20 minutes before slicing and serving.

Notes

Serve as is or with a drizzle of maple syrup or dollop of plain Greek yogurt.

To make overnight blueberry baked oatmeal or make ahead of time:

  • Bake this ahead of time and freeze slices, individually wrapped
    • Bake ahead of time and refrigerate
    • Assemble as instructed up until the blueberries are added and refrigerate overnight. Just before baking, add the blueberries and pour into your prepared pan.

    Substitution ideas

    Frozen blueberries or frozen mixed berries may be substituted for fresh.
    Brown sugar can be substituted for the maple syrup.
    For the milk, you can also use unsweetened vanilla almond milk or vanilla almond milk.
