Ingredients

Scale
  • 2 cups (160g) rolled oats (old-fashioned)
  • 1/3 cup (65g) packed brown sugar
  • 1 teaspoon cinnamon
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 2 cups (480ml) milk (whole milk or milk of choice)
  • 1 teaspoon vanilla extract
  • 1 large egg, beaten
  • 2 tablespoons butter, melted
  • 1 1/2 cups (225g) blueberries, fresh or frozen
  • 1 tablespoon lemon juice
  • 2 tablespoons sugar (for compote)

Instructions

  1. Preheat the oven to 350°F (175°C). Grease an 8×8-inch baking dish with butter or non-stick spray.
  2. In a medium bowl, whisk together rolled oats, brown sugar, cinnamon, baking powder, and salt.
  3. In a large bowl, whisk together milk, beaten egg, melted butter, and vanilla extract until smooth.
  4. Pour the dry oat mixture into the wet ingredients and stir until fully combined. Let the batter rest for 5 minutes.
  5. Pour the batter into the prepared baking dish, spreading evenly.
  6. Bake for 35-40 minutes until the top is set with a slight golden crust and a toothpick comes out mostly clean with some moist crumbs.
  7. While baking, prepare the blueberry compote by combining blueberries, sugar, and lemon juice in a small saucepan over medium heat. Cook for 8-10 minutes, stirring occasionally, until berries burst and mixture thickens. Remove from heat and let cool slightly.
  8. Let the baked oats cool for 5-10 minutes before serving. Top with blueberry compote.

Notes

Use old-fashioned rolled oats for best texture; avoid instant oats. Let batter rest before baking for creamier texture. Baking powder helps oats puff up and prevents heaviness. Frozen blueberries work well off-season. For vegan version, replace egg with flax egg and use plant-based milk and coconut oil instead of butter. Baking an extra 5 minutes can help if oats seem too wet. Store leftovers covered in fridge up to 3 days; reheat with splash of milk. Can freeze portions for up to a month.
