Here is something I haven't done in awhile...a recipe! I can't take credit for this one, though. It is from one of my favorite desserts. Trust me though, this caramel sauce can go on just about anything sweet. Nathan swears it would be fabulous on a doughnut. Yes, it is REALLY bad for you, but so worth it.
1 lb butter
1 lb Dark Brown Sugar
a couple splashes of vanilla
1 cup heavy whipping cream
Melt butter in medium saucepan, stir in brown sugar and vanilla until well incorporated. Slowly whisk in heavy whipping cream.
