Ingredients

Scale

Dry Ingredients

  • 2 cups rolled oats
  • 1 tsp baking powder
  • 1 tsp ground cinnamon
  • 1/4 tsp salt

Wet Ingredients

  • 2 cups milk (dairy or plant-based)
  • 2 large eggs (or flax eggs for vegan version)
  • 1/4 cup brown sugar

Fruit

  • 2 cups fresh blueberries

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and lightly grease an 8×8-inch baking dish to prevent sticking.
  2. Mix Dry Ingredients: In a large bowl, combine the rolled oats, baking powder, ground cinnamon, and salt, mixing evenly to distribute the ingredients.
  3. Whisk Wet Ingredients: In a separate bowl, whisk together the milk, eggs, and brown sugar until the mixture is smooth and well combined.
  4. Combine Mixtures: Gently fold the wet mixture into the dry oat mixture, stirring until just combined to avoid overmixing.
  5. Add Blueberries: Carefully fold the fresh blueberries into the mixture, taking care not to crush them to maintain bursts of fresh flavor.
  6. Transfer to Dish: Pour the combined oatmeal mixture into the prepared baking dish and spread it evenly for uniform baking.
  7. Bake: Bake in the preheated oven for about 30 minutes or until the top turns golden brown and the center is set, indicating it’s cooked through.
  8. Cool and Serve: Allow the baked oatmeal to cool slightly before cutting into squares. Serve warm for the best flavor and texture.
