The only trick you need to remember is don’t forget to line your baking dish with parchment paper.  Parchment paper will keep the cookie bars from sticking to the pan!  You can even line both the bottom and the sides of the baking dish with a huge piece of parchment.  Or you can line just the bottom of the pan, and use the knife to separate the sides of the baked cookie bars from the pan.
