Ingredients

Scale
  • 1 1/2 cups all-purpose flour
  • 2 cups rolled oats
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup (2 sticks) unsalted butter, softened
  • 1 cup packed light brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/4 cup milk
  • For the Swirl: 1/2 cup packed light brown sugar
  • For the Swirl: 1 tablespoon ground cinnamon
  • For the Glaze: 1 cup powdered sugar
  • For the Glaze: 2 tablespoons milk
  • For the Glaze: 1/2 teaspoon vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and line a 9×13 inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. In a medium bowl, whisk together the flour, rolled oats, baking soda, and salt. Set aside.
  3. In a large bowl, beat the softened butter, brown sugar, and granulated sugar with an electric mixer until light and fluffy.
  4. Beat in the eggs one at a time, then mix in the vanilla extract.
  5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Stir in the milk.
  6. In a small bowl, mix the 1/2 cup brown sugar and 1 tablespoon cinnamon for the swirl.
  7. Press two-thirds of the dough evenly into the bottom of the prepared pan.
  8. Sprinkle the cinnamon sugar mixture evenly over the dough layer.
  9. Crumble the remaining one-third of the dough over the cinnamon sugar layer.
  10. Bake for 25 to 30 minutes, or until the edges are golden brown.
  11. While the bars cool slightly, whisk together the powdered sugar, 2 tablespoons milk, and 1/2 teaspoon vanilla for the glaze.
  12. Drizzle the glaze over the warm bars. Let the bars cool completely before cutting into squares.

Notes

  • For chewier bars, slightly underbake them by about 2 minutes.
  • You can substitute whole wheat flour for half of the all-purpose flour for added fiber.
  • Store leftover bars in an airtight container at room temperature for up to four days.
