Ingredients

Scale
  • 2 cups rolled oats
  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/4 cup packed brown sugar
  • 1 1/2 cups milk (dairy or non-dairy)
  • 1 large egg, lightly beaten
  • 1/4 cup melted unsalted butter or coconut oil
  • 1 teaspoon vanilla extract
  • 1 cup fresh or frozen blueberries (optional mix-in)
  • For Streusel Topping:
  • 1/2 cup all-purpose flour
  • 1/4 cup packed brown sugar
  • 1/4 cup cold unsalted butter, cut into small pieces
  • 1/2 teaspoon ground cinnamon

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease an 8×8 inch baking dish.
  2. In a large bowl, combine the rolled oats, baking powder, cinnamon, and salt. Stir well to mix the dry ingredients.
  3. In a separate medium bowl, whisk together the milk, egg, melted butter, and vanilla extract.
  4. Pour the wet ingredients into the dry ingredients. Stir until just combined. Do not overmix.
  5. If using, gently fold in the blueberries. Pour the mixture into the prepared baking dish.
  6. Prepare the streusel topping: In a small bowl, combine the flour, brown sugar, and cinnamon for the topping. Cut in the cold butter using your fingers or a pastry blender until the mixture resembles coarse crumbs.
  7. Sprinkle the streusel topping evenly over the oatmeal mixture.
  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 to 10 minutes before cutting into squares. This is a great make ahead breakfast; store leftovers covered in the refrigerator for up to 4 days.

Notes

  • For gluten free baked oatmeal, use certified gluten free rolled oats.
  • To make baked oatmeal cups, divide the batter among 12 greased muffin cups and reduce the baking time to 20-25 minutes.
  • Serve warm with a drizzle of maple syrup or a dollop of Greek yogurt for a satisfying bite.
