Vanilla Buttermilk Syrup (tastes just like Magelby's & Kneader's)

3/4 cube butter

1 1/2 cup white sugar
3/4 cup buttermilk
1 1/2 teaspoon Karo syrup
1 1/2 teaspoon baking soda
1 1/2 teaspoon vanilla
*make sure to make this in a high sided pan

Mix butter, sugar, buttermilk, and Karo syrup. Bring to a boil. Boil for 3 minutes then TURN DOWN and add baking soda and vanilla STIRRING CONSTANTLY. This will foam tons right away and every time you heat it up again in the microwave or stove!

(It makes more than you think it will!)
