Preparing the Pan
Use a Parchment Liner
Make a Sling
With their gooey centers, it’s nearly impossible to remove some bar cookies from the pan without tearing or crumbling. Here’s our easy solution:
1. Place two sheets of foil or parchment paper perpendicular to each other in the baking pan, pushing into the corners and up the sides. Spray with nonstick cooking spray.
2. After the bar cookies have baked and cooled, use the ¬overhang to lift the whole thing from the pan. Cut into portions.
