4 cups all-purpose flour
1 cup white sugar
1 cup packed light brown sugar
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon vanilla extract
1/2 teaspoon salt
1 cup butter
1 egg
2 teaspoons milk
1 cup milk chocolate chips
Preheat the oven to 375 degrees F (190 degrees C). Grease cookie sheets.
In a large bowl, mix the flour, brown sugar, white sugar, baking powder, baking soda, and vanilla together. Stir in the salt, water, and butter. Beat in the egg and milk, then fold in the chocolate chips. Drop by rounded spoonfuls 3 inches apart onto the prepared cookie sheets.
Bake for 8 to 10 minutes in the preheated oven. Allow cookies to cool on baking sheet for 5 minutes before removing to a wire rack to cool completely.
