Believe it or not the sauce is made from white sugar, vanilla,nutmeg and water, and no brown sugar. The Brown sugar is from inside the apple!
On the stove, in a small quart pan, mix vanilla, sugar, water, nutmeg and bring to a fast boil. Remove from heat immediately
Cover each apple with about 1/2 C (ladle) of this Brown Sugar Butter Sauce. Place in oven to bake for 35-40 minutes until tops are golden brown.
