I just made this yesterday.I followed the exact ingredients and used the bakers chocolate squares.(not choc. chips like others)and I used 15 cookies instead of 10.I decided to put in the freezer instead of the fridge,since others said it took longer then specified to harden and came out too gooey.Mine came out great,I left in the freezer all day.I will be making this over and over.it tastes great and was super easy,a great receipe for young children to help make too.Mine loved crushing the cookies..lol.
