Place butter in a 10-inch ovenproof skillet. Place in a 400 degree oven for 3 to 5 minutes or until butter melts. In a medium mixing bowl use a wire whisk or rotary beater to beat eggs until combined. Add flour, milk and salt. Beat until mixture is smooth. Immediately pour into the hot skillet. Bake about 25 minutes or until puffed and well browned.
Top with fruit. If desired, sprinkle with powdered sugar or top with whipped cream. Cut into wedges and serve warm
