In a bowl of your electric mixer, place the butter, sugar, maple syrup, spices and salt. Beat on medium speed until combined and smooth. At this point, you can place the butter in a sealed container and store it in the fridge!
To make the drink, bring a pot of water to a boil. Fill your mug with 1 to 2 shots of bourbon. Add 1 to 2 tablespoons of the butter mixture into the bourbon. Fill the mug with boiling water and whisk constantly until the butter melts and dissolves. Top with whipped cream and serve.
