Pre-heat the waffle maker to medium.
In a large bowl, mix together the cake mix and beer until the batter is smooth and lump-free.
In a bowl with a hand mixer, whip the cream until soft peaks form. Add in the confectioners’ sugar, salt and the shot of liquor flavoring of your choice.
Brush the waffle maker with butter and scoop a quarter of the batter onto the waffle maker. Cook for 4-6 minutes, or until the waffle iron stops steaming. Remove and allow to cool. Repeat with the remaining batter.
Top the waffles with the whipped cream.
