Borrowed from the Bargain Hunters.
1 lb (2 sticks) butter
1/2 c white sugar
1/2 c light brown sugar
~ 1 sleeve saltine crackers
1 bag semi-sweet chocolate chips
Preheat oven to 350
Line cookie sheet (one with sides!) with foil and spray with Pam. Lay out crackers in a single layer and set aside.
Melt butter in a saucepan over medium heat. Add in both sugars and stir to dissolve. Let this cook, stirring fairly often, until it's bubbling. Let it bubble for about 5 minutes, then pour over crackers and spread as evenly as possible.
Put in oven for about 5 minutes. Remove from oven and sprinkle on chocolate chips. I've never measured, but it's probably around the size of a bag--3 or 4 big handfuls. Let it sit a few minutes and the chocolate chips will melt. When they're soft enough, spread them evenly over the crackers.
Put the whole thing in the refrigerator to cool. After it's hardened, take it out and break it up into pieces.
Eat. It is recommended to have supervision for this step, otherwise you run the risk of eating it all yourself.
