  2. Stir oats, baking powder, cinnamon, and salt in a large bowl.
  3. Whisk milk, maple syrup, egg, melted butter, and vanilla in a second bowl.
  4. Scatter 1 1/2 cups of the blueberries over the bottom of the dish. Cover with the oat mixture, then pour the liquid evenly over everything.
  5. Scatter the remaining 1/2 cup berries on top.

Notes

  • Refrigerates well for 4 days; reheat squares in the microwave for 60 seconds.
  • Use rolled oats only — quick oats turn to mush and steel-cut won't cook through.
