Ingredients

Scale
  • 2 cups rolled oats
  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1/4 cup packed brown sugar
  • 1 3/4 cups milk (any kind)
  • 1 large egg, lightly beaten
  • 1/4 cup melted butter or coconut oil
  • 1 teaspoon vanilla extract
  • 2 cups chopped fruit (like apples or blueberries)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch baking dish.
  2. In a large bowl, mix the rolled oats, baking powder, cinnamon, and salt.
  3. Stir in the brown sugar until combined.
  4. In a separate bowl, whisk together the milk, egg, melted butter, and vanilla extract.
  5. Pour the wet ingredients into the dry ingredients and mix until just combined. Do not overmix.
  6. Gently fold in your chosen fruit.
  7. Pour the mixture evenly into the prepared baking dish.
  8. Bake for 35 to 40 minutes, or until the top is golden brown and the center is set.
  9. Let the baked oatmeal cool for 5 minutes before slicing into squares.

Notes

  • For a make-ahead breakfast, you can assemble the entire dish the night before, cover it, and refrigerate. Add 5-10 minutes to the baking time if baking straight from the refrigerator.
  • This recipe freezes well. Cool completely, slice into individual portions, wrap tightly, and freeze for up to three months. Thaw overnight or reheat from frozen.
  • Add mix-ins like 1/2 cup chopped pecans or 1/2 cup chocolate chips with the fruit for extra flavor.
