  • Total Time: 38 minutes
  • Yield: 24 servings

Ingredients

Wet Ingredients

  • 1 cup unsalted butter, melted
  • 1 1/2 cups dark brown sugar, packed
  • 2 large eggs
  • 2 teaspoons pure vanilla extract

Dry Ingredients

  • 1 3/4 cup all-purpose flour
  • 2 teaspoons cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 teaspoon baking soda
  • 1 teaspoon kosher salt
  • 1 tablespoon cornstarch

Add-ins

  • 3 cups old fashioned oats
  • 2 cups raisins

Topping (optional)

  • 2 teaspoons powdered sugar

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F. Line a 13×9 inch baking dish with parchment paper to prevent sticking and set it aside.
  2. Mix Wet Ingredients: In a mixing bowl, beat the melted butter and dark brown sugar together for about 2 minutes to create a creamy base. Add in the eggs and vanilla extract and continue beating for another minute, scraping down the sides of the bowl to ensure even mixing.
  3. Add Dry Ingredients: Gradually add the flour, cinnamon, nutmeg, baking soda, kosher salt, and cornstarch to the wet mixture. Mix on low speed just until all ingredients are combined without overmixing.
  4. Incorporate Oats and Raisins: Stir in the old fashioned oats and raisins until they are evenly distributed throughout the batter.
  5. Bake the Bars: Pour the batter into the prepared baking dish, spreading it evenly. Bake in the preheated oven for 25-28 minutes or until the edges turn lightly browned and a toothpick inserted near the center comes out mostly clean.
  6. Cool and Serve: Allow the cookie bars to cool completely in the pan to set properly before cutting them into bars. Optionally, dust the cooled bars with powdered sugar for a touch of sweetness and presentation.

Notes

  • Ensure the butter is fully melted but not hot before mixing to avoid cooking the eggs.
  • Do not overbake; bars should be slightly soft in the middle after cooling.
  • Use parchment paper to easily lift the bars out of the pan for clean cutting.
  • These bars can be stored in an airtight container at room temperature for up to a week.
  • For a nut-free version, omit any added nuts or substitute with additional oats or seeds.
