Dissolve yeast in warm water and sugar in a large bowl. Add in oil, salt, egg and flour until combined. (Add a little extra flour if dough is too sticky.)
Shape immediately into about 15 rolls and place in a greased 9×13″ cake pan. Let raise for about 15-20 minutes.
Preheat oven to 375ºF. Bake rolls for about 15-20 minutes. Spread butter on the tops of cooked rolls for a finishing touch.
