Preheat oven to 350 degrees F. Grease two cookie sheets or line with parchment.

Beat the butter until creamy. Add the granulated and brown sugars and continue beating for about -5 minutes. Beat in the eggs, one at a time and beat for another minute, then beat in the vanilla and the water.

Thoroughly mix together the flour, baking soda, baking powder, and salt in a second bowl. Add the flour mixture to the butter mixture and well. Add the oatmeal, butterscotch morsels, cornflakes and nuts and mix until well combined.

Place heaping teaspoons of batter about 2 inches apart on the prepared baking sheets or shape the dough into 1 inch balls. With moistened fingertips, gently press each cookie to flatten it slightly. Bake the cookies until lightly browned, about 12 minutes. Transfer to racks to cool completely.

Makes about 80 cookies.
