Prep Time 15 minutes
Cook Time 30 minutes
Total Time 45 minutes
Servings 24 bars

Ingredients
  

  • 2 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt (use less if using table salt)
  • 1 cup unsalted butter melted and slightly cooled
  • 1 cup light brown sugar packed
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 cups semi-sweet chocolate chips or dark, milk, or a mix

Instructions
 

  • Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper or foil, leaving an overhang on the sides. You can also lightly spray the bottom with cooking spray if you prefer.
  • In a medium bowl, whisk together the all-purpose flour, baking soda, and kosher salt. Set this mixture aside for a moment.
  • In a larger mixing bowl, combine the melted and slightly cooled butter with both brown sugar and white sugar. Stir them thoroughly until smooth and well-combined.
  • Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract until fragrant.
  • Gradually add the dry flour mixture to the wet ingredients. Mix on low speed, or by hand, until just combined. Be careful not to overmix the dough.
  • Fold in the chocolate chips until they are evenly distributed throughout the dough. If you like, save a few to sprinkle on top before baking for a prettier finish.
  • Transfer the cookie dough into your prepared baking pan. Use a spatula or your hands to press the dough evenly into the bottom of the pan. Make sure it's spread from edge to edge.
  • Place the pan in the preheated oven. Bake for 25-35 minutes, or until the edges are golden brown and the center looks set but still slightly soft. A perfectly baked cookie bar will seem a little underdone in the middle when you pull it out.
  • Let them cool completely in the pan on a wire rack. Seriously, resist the urge to cut into them warm. They will continue to set up as they cool. Cutting them hot will result in a gooey, crumbly mess.
  • Once fully cooled, use the parchment paper overhang to lift the entire slab out of the pan. Place it on a cutting board and slice into squares or rectangles. Now, your delicious dessert bars are ready to enjoy!

Notes

Achieving perfect chocolate chip cookie bars isn't hard, but a few key tips can elevate your results. First, don't overmix your dough. Overmixing develops the gluten in the flour too much, which can lead to tough, dense bars. Mix until just combined. Second, do not overbake them. You want the edges to be golden, but the center should still look slightly soft and gooey. They will continue to cook and set as they cool, so pulling them out a little early ensures that signature chewy center. Third, cooling is non-negotiable. I know it's hard to wait, but cutting into warm bars results in a messy, crumbly texture. If you want neat, firm squares, allow them to cool completely. This means several hours at room temperature, or even chilling them in the fridge.
These classic dessert bars are fantastic as is, but don't hesitate to experiment with different additions to make them your own. For a richer flavor, swap out some of the semi-sweet chocolate chips for dark chocolate chunks. You could also mix in white chocolate chips, butterscotch chips, or even chopped nuts like pecans or walnuts for added texture. If you love a salty-sweet combo, sprinkle a little flaky sea salt on top of the dough before baking. Another popular variation is adding toffee bits. Stir them into the dough, or sprinkle them on top for a delightful crunch. For a seasonal twist, try adding a half teaspoon of cinnamon or a dash of pumpkin spice. You can even drizzle a simple glaze over the cooled treats for an extra touch of sweetness. The possibilities are endless for customizing your favorite dessert!
**FAQ:**
* **Can I make these chocolate chip cookie bars ahead of time?** Absolutely! These chocolate chip cookie bars are an excellent make-ahead dessert. You can bake them up to 2-3 days in advance and store them in an airtight container at room temperature. They taste just as good, if not better, the next day as the flavors meld.
* **How do I store and freeze leftover dessert bars?** Store cooled bars in an airtight container at room temperature for up to 4 days. If you want to freeze them, wrap individual squares or the whole slab tightly in plastic wrap, then aluminum foil. They'll keep well in the freezer for up to 3 months; just thaw at room temperature before serving.
* **Why are my Cookie Bars crumbly or too hard?** Crumbly Cookie Bars often mean they were cut too soon before fully cooling, or they might have been overbaked. Hard bars usually indicate overbaking. Keep an eye on them in the oven and always let them cool completely in the pan to achieve that perfect chewy texture. Next time, try taking them out when the center still looks slightly soft.
