Line a cookie sheet with foil then cover completely with the crackers.
Heat sugar and butter slowly until it boils, then stir constantly for 4 minutes. Pour carefully over crackers. Place pan in pre-heated oven at 325 degrees for 16 minutes.
Shake chocolate chips over top of mixture after removing from oven. They will melt in about 5-10 minutes. Use a spoon or spatula to smooth out the chocolate, let this cool down for 15 minutes (at least), then freeze them for at least 1 hour before you break them. Keep refrigerated and serve cold.
