Loaded with oats, brown sugar, and melty chocolate chips, these oatmeal cookie bars are thick, chewy, and made in a single batch. No cookie scoop required!

Ingredients

  • 1 cup (227g) salted butter
  • ¾ cup (137g) brown sugar
  • ½ cup (100g) granulated sugar
  • 2 large eggs
  • 1 Tablespoon vanilla
  • 1 ½ cups (210 g) all-purpose flour
  • 2 cups (170g) old fashioned oats
  • ½ teaspoon salt
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1 ½ cups chocolate chips (plus a little more to put on top)

Instructions

  • Preheat and prepare: Preheat oven to 350°F. Line a 9x13 baking dish with parchment paper, or spray with non-stick cooking spray.
  • Beat wet ingredients: In a large mixing bowl, add 1 cup butter, 3/4 cup brown sugar and 1 cup granulated sugar. Beat for 2 to 3 minutes, until fluffy and light. Add 2 eggs and 1 Tablespoon vanilla and continue to beat until well incorporated.
  • Add dry ingredients: In a medium sized bowl, whisk together 1 1/2 cups flour, 2 cups oats, 1/2 teaspoon salt, 1 teaspoon baking soda and 1 teaspoon baking powder. Combine the dry ingredients with the wet ingredients, mixing until just combined. Add 1 1/2 cups chocolate chips.
  • Bake: Transfer dough to prepared baking dish and press firmly so it's even throughout the pan. Add some additional chocolate chips on top. Bake for 25 minutes.
  • Cool: Allow the bars to cool completely before serving.

Notes

Storage: Store bars in an airtight container for up to 5 days at room temperature. If cut, place parchment paper between layers.
Freezer: These bars freeze well for up to 3 months! Wrap them in plastic wrap, and then again in foil or a ziplock bag. Thaw at room temperature.
