Ingredients 

  • 2 cups old fashioned oats
  • ½ cup brown sugar
  • 2 teaspoons ground cinnamon
  • 1 ¾ cups whole milk
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 3 tablespoons salted butter melted
  • 2 cups frozen mixed berries

Instructions

  • Preheat your oven to 350°.
  • Combine the oats, brown sugar, and ground cinnamon in an 8×8 inch baking dish.
  • In a separate bowl, whisk together the milk, egg, vanilla, and melted butter.
  • Add the milk mixture to the baking dish and fold the ingredients together. Ensure that the oats are evenly covered in the milk mixture.
  • Scatter your fruit over the top of the dish and bake uncovered for 40 minutes.
  • Allow your baked oatmeal to cool for 15 minutes before serving.
  • Slice into squares and enjoy!

Notes

  • Allowing your baked oatmeal to cool down a little bit helps cook off some extra moisture, which makes the oatmeal easier to slice and serve.
  • Make sure you are using old fashioned oats. We found that with quick oats the baked oatmeal was still quite wet after it baked.
  • To store your leftover baked oatmeal, allow it to cool down completely. You can either cover the baking dish with tin foil/ plastic wrap or transfer it to an airtight container.
  • Other spices you can add to your baked oatmeal include nutmeg and cloves.
