This rich and flavorful bourbon stout syrup reminds of chocolate syrup but with subtle roasty notes of coffee, caramel, and bourbon. It pairs wonderfully with vanilla ice cream and can also be used in an Old Fashioned cocktail.
Gently heat all ingredients on very low heat until sugar melts. Do not simmer or “cook” the beer. Let cool and store in the fridge in a sealed container for up to 2 weeks. Serve over ice cream.
