One stick of butter. Not at room temperature, because I never remember to set one out beforehand, but melted. One egg, with no leftover egg whites to deal with. Equal amounts of light brown and white sugars.

Keeping the ingredients as streamlined as possible was the goal and we were able to achieve the BEST classic chocolate chip cookie bars in the process.

While I love a good cookie, like our Thick Chocolate Chip Cookies. I love cookie bars just as much! Our Monster Cookie Bars and our Oreo Bars have been some of my favorite desserts. So a basic Chocolate Chip cookie bar was needed for our recipe collection.
