Buttermilk Caramel Syrup

I found this recipe at Creations by Kara and tried it out this weekend. I am not a huge maple syrup fan so I am always looking for alternatives and I've gotta say this one is super yummy!

Buttermilk Caramel Syrup

1 1/2 cups buttermilk
1 cup sugar
1 cup brown sugar
1/4 cup butter
1 tsp baking soda
1 tsp vanilla

In a large (seriously - use a large!) saucepan, bring buttermilk, sugars, and butter to a boil over medium heat. Remove from heat and stir in soda and vanilla. It will bubble up a lot. As it cools, the bubbles will go away.
