Preheat oven to 350 degrees F.
Completely cover a baking sheet with salted soda crackers.
In a saucepan, melt the butter and sugar. Pour melted mixture over the salted soda crackers, try to cover all of them. Bake crackers in 350 degree F. oven for exactly 10 minutes. Remove from oven after 10 minutes and pour chocolate chips over the crackers immediately. Let sit about 5 minutes, until chips have softened. Spread the softened chips completely over the crackers and sprinkle with whatever topping you like. Place in refrigerator until cool. Break into pieces and enjoy.
