First, grab a baking dish and the materials. If you want to secure the parchment paper to the pan extra well, then start by lightly spraying the pan with the cooking oil spray.
Next, measure how big of a piece you need by putting the parchment sheet flat over the top of the dish. Cut the paper so it is about 1.5- 2 inches wider than the baking pan.I prefer to use a parchment paper sheet so they don't curl like the rolls of parchment do.
Then, use the scissors to cut one slit in the parchment at each of the corners of the baking dish across from each other.
Repeat for all 4 corners.
Finally, gently push the parchment paper into the pan, and fold the corners so the paper fits securely. Now you’re ready to bake!
