Dad's a little vague on the ingredient quantities. 

Take one ripe, but firm banana for two people.
Divide it into 4 quarters.
Sauté in butter and brown sugar, turning once.
Place one half on each dessert plate and cover with a 1/4" slice of vanilla ice cream.
Spoon some of the hot butter and sugar mixture from the skillet on each serving.
It's rich and tasty.
