Cook noodles in boiling salted water until almost done. Drain. Place in a mixing bowl with butter; toss to coat. In a separate bowl, beat eggs, milk and sugar until well blended. Combine with noodles. Pour into a greased 13x9 inch baking pan. Bake at 350 for about 35 minutes or until puffy and noodles begin to brown at edges. Cut into squares and serve hot or cold with fruit preserves.
