We're using pantry staples and buttermilk to create a rich and indulgent ButtermilkSyrup with a hint of vanilla flavor. This syrup can be made in under ten minutes on the stovetop.
In a medium-sized pot (bigger than you think, because this syrup doubles or triples in volume!) add in the loosely measured 1/4 cup of dark or light brown sugar, 3/4 cup white sugar, 1/2 cup butter, 1/8 teaspoon salt, and 1/2 cup buttermilk. Heat over medium heat and stir occasionally until butter melts, sugar dissolves and syrup is smooth. Reduce the heat to low and simmer for 6-8 minutes. Remove from heat and immediately stir in 1/2 teaspoon baking soda. Whisk quickly to dissolve and evenly disperse the soda. The volume of the syrup will greatly increase. Stir in vanilla extract.
Serve warm over breakfast of your choice. The syrup continues to thicken as it cools.
Store in an airtight container for up to 2 weeks in the fridge. To serve, warm gently on the stovetop over medium-low heat.
