Vanilla Butter Syrup

1 cup butter (2 cubes)
1 cup brown sugar
1 1/2 cups half & half
1 TBSP corn syrup
1/2 tsp baking soda
2 TBSP vanilla

Add butter, brown sugar, half & half and corn syrup to a medium sized saucepan on medium heat. Stir to combine as butter melts and mixture melds together. Bring mixture to a boil and boil for 5 minutes. Remove from heat. Add baking soda and whisk quickly- syrup increases in size, so be ready! Keep gently whisking until it simmers down. Add in good quality vanilla and whisk intermittently until syrup is all one color.
