Preheat oven to 325°. Lightly grease a 8 x 4 x 2 loaf pan.
Combine water, ¾ cup melted butter, egg and pound cake mix in large bowl; blend well. DO NOT OVER MIX; batter may be lumpy.
Spread in loaf pan and bake 65-75 minutes or until toothpick comes out clean. (you may cover with foil the last 15 minutes if the cake is getting too browned.)
Cool completely and remove from pan.
