Step-by-Step Blueberry Baked Oatmeal Recipe
Ingredients You’ll Need
- 2 medium ripe bananas, sliced into ½-inch pieces
- 1½ cups fresh or frozen blueberries
- ¼ cup honey or pure maple syrup
- 1 cup quick or old-fashioned oats
- ¼ cup chopped walnuts or pecans
- ½ teaspoon baking powder
- ¾ teaspoon ground cinnamon
- Pinch of salt
- 1 cup milk (any dairy or non-dairy milk of your choice)
- 1 large egg
- 1 teaspoon alcohol-free vanilla flavor (Simply Organic Alcohol-Free Vanilla Flavor or Watkins Clear Vanilla Flavor)
Instructions
- Preheat and Prepare: Preheat your oven to 375°F. Lightly spray an 8×8-inch or 9×9-inch ceramic baking dish with cooking spray and set it aside.
- Layer the Fruit: Arrange banana slices evenly across the bottom of the baking dish. Sprinkle half the blueberries on top, add ¼ teaspoon cinnamon, and drizzle 1 tablespoon of honey. Cover the dish with foil.
- Bake the Base: Bake for 15 minutes until the bananas soften and begin to caramelize slightly.
- Combine Dry Ingredients: In a medium bowl, mix oats, half of the chopped nuts, baking powder, remaining cinnamon, and salt. Stir well to combine.
- Whisk the Wet Ingredients: In another bowl, whisk the rest of the honey with milk, egg, and alcohol-free vanilla flavor until smooth.
- Assemble: Remove the dish from the oven. Spread the oat mixture evenly over the warm bananas and blueberries. Slowly pour the milk mixture on top, distributing it evenly so all oats are moistened.
- Add Toppings: Sprinkle the remaining blueberries and chopped nuts over the top for extra crunch and flavor.
- Bake to Perfection: Return the dish to the oven and bake for 30 minutes, or until the top is golden brown and the oatmeal is set.
- Serve and Enjoy: Allow it to cool slightly before slicing into six pieces. Serve warm for the best flavor and texture.
