These cookie bars would make a great after school treat.
1/2 cup butter
1/2 cup packed brown sugar
2 tablespoons water
1 (18.25 ounce) package white cake mix
1 cup chopped walnuts
2 cups semisweet chocolate chips
Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13 inch baking pan. In a large bowl, cream together the butter and sugar until light and fluffy. Mix in water and egg, then stir in cake mix. Finally, mix in nuts and chocolate chips. Spread mixture into pan. Bake for 30 to 35 minutes in the preheated oven. Cool completely before cutting into bars.
