Ingredients

  • 1 1/2 cups rolled oats (not instant)
  • 1/4 cup packed light brown sugar
  • 1 teaspoon baking powder
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1 1/2 cups milk (dairy or non-dairy)

Instructions

  1. Preheat oven to 375°F (190°C). Grease an 8x8 inch baking dish.

  3. In a separate medium bowl, whisk together the milk, beaten egg, melted butter, and vanilla extract.
  4. Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix.
  5. Gently fold in the blueberries, reserving a few for topping if desired.
  6. Pour the mixture into the prepared baking dish and spread evenly.

  8. Bake for 25-30 minutes, or until the edges are set and the center is cooked through.
  9. Let cool slightly before serving. Serve warm with your favorite toppings.

Tips

  • Use rolled oats (old-fashioned) for the best texture; instant oats can become mushy.
  • If using frozen blueberries, do not thaw them before adding to the batter; this prevents the batter from becoming too wet.
  • For a richer flavor, consider using half-and-half or whole milk instead of lower-fat options.
