Easy and Yummy...though a bit odd sounding when you read the recipe. I haven't made it in years, so the times are estimated. But I remember it being pretty quick to make besides the chilling. Chilling time is included in prep time.
Cover a cookie sheet with aluminum foil, then line with crackers.
Preheat oven to 350* F.
In a sauce pan, melt butter and brown sugar over medium heat until it reaches hard ball texture - 250*F on a candy thermomator OR if you don't have one when a small amount is dripped into chilled water a ball is formed that is rigid but still pliable.
Pour the mixture over crackers and put in the oven until bubblely (about 5 minutes).
Take out and sprinkle chocolate chips over crackers and candy then return to oven until the chocolate chips melt a little (2 - 5 min).
Remove from oven again and spread chocolate evenly around, sprinkle with walnuts if you wish.
Chill in the refrigerator for 1 1/2 to 2 hours then peel off foil and break or cut into pieces.
