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
- 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.
- 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.
- 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.
- Incorporate Oats and Raisins: Stir in the old fashioned oats and raisins until they are evenly distributed throughout the batter.
- 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.
- 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.
