Line a cookie sheet with foil and grease it. Then, cover cookie sheet with club crackers. It will use the entire sleeve, minus one or two. Preheat oven to 400 degrees. In a pot add, 1 and half sticks of butter and 1 cup of brown sugar, once is starts boiling, let it boil for 3 minutes. Pop the crackers only into the oven for literally 2 minutes or less. They will burn fast, believe me.
Cover and let it sit overnight to harden. If you do not have that kind of time, you can always pop it into the frig for 45.
Then, break it into pieces or cut it into bite size squares. Again, pretend like this picture is flipped the right way.
