These Chocolate Chip Cookie Bars transform everyone’s favorite cookie into thick, soft and chewy, chocolate bar cookies. Easy recipe that serves a crowd!
Preheat the oven to 350 degrees F. Line a 13x9 baking dish with parchment paper and set it aside.
In a large mixing bowl, combine butter and both sugars for about 2 minutes, until fully blended. Add in vanilla and eggs and beat until well mixed.
Add in flour, baking soda, and salt. Beat JUST until fully combined. Fold in 2 1/2 cups of the chocolate chips.
Press cookie dough into the bottom of the prepared baking dish. Sprinkle the remaining chocolate chips onto the top of the cookie dough.
Bake for 24-28 minutes until the outside of the cookie bar is lightly browned. Remove from the oven and cool completely before slicing.
Notes
Soften the butter by setting it on the countertop for at least 30 minutes before you start the recipe. This ensures that it incorporates smoothly and evenly into the dough.
To keep the parchment paper from slipping, you can spray the pan with cooking spray and then line it with the parchment. The spray will help the parchment stick in place without sliding. I also use binder clips on my pan, just be sure to remove before baking.
Don't overmix the dough once you add in the flour, otherwise your cookie bars will be tough.
Store these chocolate chip cookie bars in an airtight container at room temperature for up to 3 days. You can also freeze them for longer storage. Slide them into a freezer bag and store them in the freezer for up to 3 months. I like to warm them up in the microwave so the chocolate chips get melty!
