THIS IS MY NEW WAY:
This really works! Lining a square pan is never easy but this way is so much better. A few people shared this concept of crumpling up the paper into a ball and then pressing it into the pan. I was a little skeptical but decided to try it and this is now the only way I line a square pan. My old way is below…
When making granola bars or bar cookies, lining the pan with parchment paper is not easy because it won’t always stay in place, but I found an easier way to do it… with binder clips. You can get them at a stationery store and since they’re metal, they can go right in the oven. Cut two parchment paper pieces a little bit wider than your 9-inch pan and lay them in, criss-crossing each other, clipping the ends down as you go. It will keep the paper in place and you won’t have to wash the pan. To save money, since parchment paper costs more than aluminum foil, here is another way:
Line the pan with foil first. Then cut a strip of parchment paper the same width as your pan, either 8 or 9 inches, and lay it on top of the foil, clipping in place. This way is easier, parchment paper releases food well, and you’ll save money! – Jenny Jones
