In a stand-mixer, fitted with the dough hook, combine butter, egg, flour, sugar, salt, yeast and water. (No need to proof the yeast in the water first)

Mix together on low speed until combined and a dough forms. Knead dough for 7 minutes or until it is soft and smooth. There should not be any dry bits of dough in the bottom of the bowl. If there is, add another tablespoon of water and continue to knead until dough is smooth.

Spray a large bowl with non-stick spray and place dough inside. Turn to coat and then cover bowl with a dish towel or saran wrap. Let dough rise until doubled in size. About 1 1/2 hours.

Once dough has risen, remove from bowl and set on a clean work surface. Separate dough into 8 equal pieces. (I used my kitchen scale and weighed each at 3.25 ounces each so they would be exactly even) Shape each piece into a ball. Transfer the dough balls onto a parchment lined baking sheet. Flatten each ball with your hand so it looks like a disc.

Cover the rolls and let rise again until noticeably puffy.

Preheat oven to 375° F. Brush rolls with half of the melted butter. Bake for 15-18 minutes, or until golden. Remove from oven and brush each roll with the remaining melted butter. Let cool before serving.
