For cookies, biscuits and scones: Line sheet pans with parchment paper before using. Prevent sticking without adding any extra grease and cleanup is as easy as throwing away the parchment.
For cakes: Line the bottoms of your cake pans with parchment paper and then either grease and flour, or coat with baking spray. You’ll never have a cake stick in your pan again!
For bars and breads: Line square or rectangular pans with parchment so that there’s a few inches of overhang on either side. When your baked good is ready to serve, use that overhang as a handle to lift it out of the pan. Then transfer to a cutting board and slice. No more messing up a slice trying to dig it out of the pan!
