Add sugar and butter to a saucepan. Heat mixture over high heat and bring to a full boil. Boil for 4 minutes.

While it boils, line a jelly roll pan with foil. Add a layer of Club crackers to the jelly roll pan.

Pour the butter mixture over the crackers. Bake the crackers in a 350 degree oven for 10 minutes.

Remove the crackers from the oven and top them with a bag of chocolate chips. Let the chips melt, then spread the chocolate over the crackers. Top with mini marshmallows.

Place the pan under the broiler just long enough to toast the mini marshmallows.

Let cool, then place in the freezer for 1-2 hours. Remove from the freezer, and crack the candy into bite sized pieces.
