I made granola bars, and the recipe indicated using parchment paper to line the cookie sheet before baking. Since I had no parchment paper, I used wax paper thinking it would have the same effect. After cooking, then cooling the granola bars, the wax paper stuck to the bottom of the granola so severely that it would not come off no matter what! I ended up throwing the granola bars away. Who wants to eat wax paper??? Next time I'll try the parchment paper!
