This 3 ingredient cocktail was created as a riff on a bourbon manhattan. To balance out the whiskey, coffee liqueur adds a touch of sweetness and depth. Today we’re using Tia Maria because its rich vanilla notes compliment the bourbon, but feel free to try this with other coffee liqueurs. Remember some liqueurs are sweeter than others, so you may need a touch of sugar to balance it out. Give this one a try if you’re looking for a smooth whiskey sipper! Cheers!
