Add 2 oz of bourbon and 1 oz of vanilla syrup to the shaker.
Using the muddler, gently press down on the vanilla bean to release its flavor. Add the muddled vanilla bean to the shaker.
Close the shaker and shake well for about 10 seconds.
Place ice cubes in the rocks glass.
Use a strainer to pour the contents of the shaker over the ice cubes in the rocks glass.
Top off the glass with 4 oz of cola.
Stir gently and garnish with a fresh vanilla bean if desired.
Enjoy your Vanilla Bourbon Cola!
Notes
You can use any type of bourbon for this recipe, but a smooth and slightly sweet bourbon will pair best with the vanilla.To make the drink stronger, increase the amount of bourbon to 3 oz.If you don't have vanilla syrup, you can make your own by mixing equal parts of sugar and water and adding a splash of vanilla extract.For a fun twist, use vanilla bean infused cola instead of regular cola.
