Ingredients for Blueberry Baked Oatmeal with Streusel Topping

For the oatmeal base:

  • 2 cups rolled oats
  • 1 tsp baking powder
  • 1 ½ tsp ground cinnamon
  • ½ tsp salt
  • 1 ¾ cups milk (dairy or plant-based)
  • 1 large egg
  • ⅓ cup maple syrup or honey
  • 2 tsp vanilla extract
  • 1 ½ cups fresh or frozen blueberries

For the streusel topping:

  • ⅓ cup brown sugar
  • ½ tsp ground cinnamon
  • 4 tbsp cold unsalted butter, cut into small pieces
  • Optional: ¼ cup chopped walnuts or pecans

How to Make Blueberry Baked Oatmeal with Streusel Topping

Step 1: Preheat and prepare your baking dish

Preheat the oven to 350°F (175°C). Grease a 9×9-inch baking dish or line it with parchment paper.

Step 2: Mix dry ingredients

In a large bowl, combine the rolled oats, baking powder, cinnamon, and salt.

Step 3: Combine wet ingredients

In another bowl, whisk together the milk, egg, maple syrup (or honey), and vanilla extract until smooth.

Step 4: Assemble the oatmeal

Pour the wet ingredients into the dry ingredients and stir until fully combined. Gently fold in the blueberries.

Step 5: Prepare the streusel topping

In a small bowl, mix the flour, brown sugar, and cinnamon. Using your fingers or a pastry cutter, cut the cold butter into the mixture until it forms coarse crumbs. Stir in nuts if using.

Step 6: Bake

Pour the oatmeal mixture into the prepared baking dish. Sprinkle the streusel topping evenly over the oatmeal. Bake for 40-45 minutes until the top is golden and the oatmeal is set.

Step 7: Serve and enjoy

Let the baked oatmeal cool for a few minutes before serving. It’s delicious warm or at room temperature. Pair it with a drizzle of yogurt or a splash of milk if desired.

Tips for the Best Blueberry Baked Oatmeal

  • Use fresh or frozen blueberries—both work well! Just toss frozen berries in a little flour to prevent them from sinking.
  • For extra texture, add chopped nuts or seeds inside the oatmeal or on top of the streusel.
  • Customize sweetness to your preference by adjusting the maple syrup or honey.
  • Store leftovers covered in the fridge for up to 4 days and reheat before serving.

Nutritional Benefits of Blueberries and Oats

Blueberries are rich in antioxidants and vitamins, supporting brain and heart health. Rolled oats provide a great source of soluble fiber, which helps regulate blood sugar and keeps you feeling full longer. Together, they make a powerhouse breakfast that’s both delicious and nourishing.

Can I make this recipe gluten-free?

Yes! Use certified gluten-free rolled oats and substitute the all-purpose flour in the streusel with almond flour or gluten-free flour.

Can I prepare this the night before?

Absolutely! Prepare the mixture, refrigerate overnight, and bake fresh in the morning.

Can I substitute blueberries with other fruits?

Yes, raspberries, blackberries, or chopped apples work great as alternatives.

How long does leftover baked oatmeal last?

Store leftovers covered in the refrigerator for up to 4 days. You can reheat in the microwave or oven.
