  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon fine sea salt
  • 2 cups whole milk
  • 2 large eggs , room temperature
  • 2 tablespoons unsalted butter, melted and cooled
  • 1 teaspoon pure vanilla extract
  • 1/4 cup light brown sugar (for swirl)

  • 2 tablespoons unsalted butter, melted (for swirl)
  • 2 ounces cream cheese, softened (for glaze)
  • 1/2 cup powdered sugar (for glaze)
  • 1 tablespoon whole milk (for glaze)

Instructions

  • Preheat oven to 350°F (175°C) and grease an 8x8-inch square baking pan with butter or non-stick spray.
  • In a large mixing bowl, whisk together the rolled oats, 1/2 cup brown sugar, baking powder, 1 teaspoon cinnamon, and sea salt.
  • In a separate medium bowl, whisk together 2 cups milk, eggs, 2 tablespoons melted butter, and vanilla extract until homogenous.
  • Pour the liquid mixture over the dry ingredients and stir with a spatula until the oats are thoroughly hydrated.
  • Transfer the oat mixture into the prepared baking pan, spreading it into an even layer.
  • In a small bowl, prepare the swirl by mixing 1/4 cup brown sugar, 1 tablespoon cinnamon, and 2 tablespoons melted butter until it forms a paste.
  • Drop small dollops of the cinnamon paste onto the surface of the oats and use a butter knife to swirl the mixture into the top layer of the oatmeal.
  • Bake for 30 to 35 minutes, or until the oatmeal is set in the center and the edges are slightly golden brown.
  • While the oatmeal cools slightly, whisk the softened cream cheese, powdered sugar, and 1 tablespoon milk until a smooth, pourable glaze forms.
  • Drizzle the glaze over the warm oatmeal squares and slice into 9 equal portions for service.
