Homemade buttermilk syrup is buttery, sweet and so much better than store bought syrup.
In a large pot, bring to a boil the first four ingredients: buttermilk, sugar, butter, and corn syrup.
Stirring constantly over medium high heat until well combined.
Remove from heat. Add in the baking soda. The baking soda will have a chemical reaction with the buttermilk, and it will bubble up big. Having it off the heat and stirring constantly will help it not boil over.
Finish by stirring in the vanilla. Let the bubble deflate and give it a few stirs before serving.
Serve warm over pancakes, waffles, french toast and our favorite: german pancakes.
Store in a wide mouth mason jar in the fridge.
