Magnificent Mini Bar Cookies

This recipes was on the back of the mini bar chocolate pieces (It's also on their website in the link) and it was really good. I had used some of the mini bars for somethings else, so I had to substitute come milk chocolate chips (not semisweet) to make up for it. I also used just margarine, and not shortening, because I didn't feel like getting out the shortening.
But I just learned this cool trick from my SIL Amy. If you line the measuring cup with plastic wrap before you fill it with shortening then it comes out easy, and you don't have to clean the measuring cup! Why hadn't I figured that out before?!!!
