Buttermilk Caramel Syrup

We made this to top Cookie Sundae Cups- um, it was soooo good!!!  It's not healthy at ALL - but it probably the best sauce I've ever put on top of my ice cream, um ever!!!

Makes 2 cups - OBB Cookbook

Ingredients:
3/4 cup buttermilk (TIP: Take1 tablespoon of white vinegar - and add enough milk to make 1 cup.  Mix - and let sit.  Then you have your buttermilk to use)
1 1/2 cups sugar
1/2 cup real butter (no subs!!)
2 tablespoons corn syrup
1 teaspoon baking soda
1 teaspoon vanilla

Combine buttermilk, sugar, butter, corn syrup, and baking soda in a 4-quart pan.

Bring mixture to boil and reduce heat to low - just make sure it's still bubbling.  Cook, stirring frequently, for 7-9 minutes or until the syrup reaches a rich golden brown.  Remove from heat and stir in vanilla.
