Ingredients

Scale

Main Ingredients

1 cup butter (227g), room temperature
1 cup light brown sugar (220g), packed
1/2 cup granulated sugar (100g)
2 large eggs
2 teaspoons vanilla extract
1/2 teaspoon salt
1 teaspoon baking soda
1 teaspoon baking powder
1 1/2 cups all-purpose flour (188g)
2 cups old-fashioned rolled oats (170g)
2 cups chocolate chips (340g) semi-sweet, milk chocolate, or a combination

Instructions

Preheat Oven: Preheat the oven to 350°F (180°C). Lightly grease a 9 x 13 inch pan with cooking spray or line it with parchment paper to prevent sticking.
Beat Butter and Sugars: In a large mixing bowl, beat together the room temperature butter, light brown sugar, and granulated sugar until the mixture is smooth and light in color, creating a creamy base.
Add Eggs and Vanilla: Add the eggs one at a time to the butter and sugar mixture, mixing thoroughly after each addition to ensure even incorporation. Then stir in the vanilla extract for flavor.
Mix Dry Ingredients: In a separate medium bowl, whisk together the salt, baking soda, baking powder, all-purpose flour, and old-fashioned rolled oats until evenly combined.
Combine Ingredients: Gradually add the dry ingredient mixture into the creamed wet mixture, stirring until just combined. Carefully fold in the chocolate chips to distribute them evenly throughout the batter.
Bake the Bars: Press the cookie dough evenly into the prepared 9 x 13 inch pan. Bake in the preheated oven for 25 to 30 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean.
Cool and Serve: Remove the pan from the oven and allow the cookie bars to cool completely in the pan before cutting into bars to ensure they hold their shape.

Notes

Using room temperature butter ensures it creams properly with the sugars for a better texture.
You can mix semi-sweet and milk chocolate chips for varied sweetness.
Make sure not to overbake; bars should be golden but still soft inside for the best chewiness.
Line your baking pan with parchment paper for easy removal and cleanup.
Store bars in an airtight container at room temperature for up to 5 days, or freeze for longer storage.
