I'll never forget the time that my great grandmother showed up with a pan of chocolate chip bar cookies. Her regular cookies were good, but these chewy morsels were hard to beat. I thought this invention of hers was genius, and begged her to always bake her cookies that way. It wasn't until years later when I saw a recipe on the back of the package of chips that I realized that these weren't her special creation, she was just trying out a new recipe.
One of the best things about bar cookies is that you can pretty much spread any drop cookie into a pan and bake them as one giant cookie. The edges bake up firm and crispy while the center remains moist and a little underdone.
In the mood for a chocolate cookie but not up for scooping, I reworked the ingredient amounts of a favorite cookie so that it fit a 9-inch square pan. Not too shallow, not too deep, and chock full of chocolate chips, nuts, and white chocolate chips, I might not go back to my old recipe again.
