This rich, buttery buttermilk syrup has a hint of vanilla and comes together in just 10 minutes! It's easy to make with simple ingredients and tastes amazing over pancakes, waffles, and French toast.
Combine: In a pot (see note 1), combine the brown sugar, granulated sugar, butter, salt, and buttermilk. Heat over medium heat, stirring occasionally, until the butter melts, the sugar dissolves, and the mixture is smooth.
Simmer: Reduce heat to low and gently simmer for 6–8 minutes, stirring occasionally.
Add baking soda: Remove the pot from the heat. Add the baking soda and whisk quickly to fully incorporate. The syrup will foam up and increase significantly in volume.
Finish & serve: Stir in the vanilla extract. Serve warm over pancakes, waffles, French toast, or your favorite breakfast foods. The syrup thickens as it cools, so don't worry if it seems a little thin right off the stove! If it gets too thick, just warm it up again until smooth and pourable.

Notes
Note 1: Use a pot much larger than you think you'll need! The syrup will foam up to 2–3 times its original volume when the baking soda is added.Storage: Store cooled syrup in an airtight container in the refrigerator for up to 2 weeks. Reheat gently on the stovetop over medium-low heat, stirring until smooth.
