Add the maple syrup to a small saucepan over a medium-high heat. Bring it to a simmer. Be careful. If you don’t keep an eye on it, it can boil over.

Add in the bourbon, vanilla extract, and butter. Return to a simmer and cook for 1 minute.

You can make this ahead of time too. A layer of butter will form on the top when cooled but easily mix in when warmed back up.

Once opened, maple syrup will last about a year in the fridge. So lots of reasons to make these waffles! Butter lasts about 4 months in the fridge but up to a year when frozen.

You can veganize this by excluding the butter. I have not tested it with vegan butter.
