I have made this for years, but had never measured any of it but the baking soda, so now that I know just how much of each ingredient I use, I can share this with all of you. I learned to make this many years ago, for I always have leftover buttermilk, so what better way to use it, than to make it sweet. My kiddos love this syrup, so in my opinion its amazing.
1 Stick Butter
1 C Buttermilk
1 C White Sugar
1/2 C Brown Sugar
2 T Karo Syrup
1 tsp. Baking Soda
1-2 tsp. Vanilla Flavoring (amount depends on personal taste)
-Over medium low heat, melt butter, whisk in sugars, karo, and buttermilk. Cook about 2 minutes, add in baking soda, continue to whisk for 1 minute.
-Remove from heat, stir in vanilla. Allow syrup to cool a bit before serving. Please note, that as it cools it will thicken. Enjoy!
Store in fridge, in airtight container, good about 2 weeks.
