1 box cake mix, any kind
1 tbsp. butter
1 or 2 eggs, depending on size
2 tbsp. water for crisp cookies or 1/4 c. water for soft cookies

Mix all together. This batter can be formed in a roll and chilled, then sliced, or dropped by teaspoon for dropped cookies, or made into balls and flattened. Bake in a 375 degree oven for 8 to 10 minutes on a greased cookie sheet.
