Notes
Add some coconut and pecans for some added texture and flavor! Simply remove ½ cup of each type of chocolate chips in the batter and replace with ½ cup sweetened coconut and ½ cup chopped pecans.Don't overbake! One of the things I love most about this recipe is the chewy, dense interior of these bars. Overbaking them will make them more crunchy and less chewy.Cut like a pro! To cut these cookie bars with clean edges, here's how to do it: Let the pan of bars cool completely (refrigerate to speed up this process). Use a knife to cut the bars down the center (so you're only working with half of the pan at a time). Remove an entire half from the pan onto a cutting board and cut with a chef's knife; repeat with the other half.
