Ingredients

  • ½ cup cold heavy whipping cream
  • ½ cup Marshmallow Fluff plus more for garnish
  • 1 tablespoon light brown sugar
  • ounces Irish whiskey
  • ounces peanut butter whiskey
  • 4 ounces strong, hot coffee
  • tablespoons smooth peanut butter
  • 1 slice white bread

Instructions

Prepare the cream:

  • Pour the ½ cup cold heavy whipping cream into a small bowl; add in the ½ cup Marshmallow Fluff. Use a hand mixer to beat them together for one to two minutes—the cream should be thickened but still pourable.
  • Hold the marshmallow-cream mixture aside.

Warm the glass and add sugar:

  • Run hot water into an Irish coffee glass two or three times until the glass is warmed. Shake out any excess water, and dry the outside.
  • Spoon 1 tablespoon light brown sugar into the bottom of the Irish coffee glass.

Add the alcohol:

  • Pour the 1½ ounces Irish whiskey and 1½ ounces peanut butter whiskey into the glass.

Add the coffee:

  • Pour the 4 ounces strong, hot coffee into the glass. Use a spoon to gently stir the ingredients together.

Add the cream:

  • Slowly pour the marshmallow-cream mixture over the back of a warm spoon onto the top of the coffee. It should float on the top to create a thick, creamy top to the drink.

Create the garnish:

  • Spread 1½ tablespoons smooth peanut butter on half of 1 slice white bread and marshmallow fluff on the other half. Sandwich them together. Slice out a small, square fluffernutter sandwich. (You can eat the leftover parts!)
  • Skewer the mini sandwich on a shamrock cocktail pick and add it to the drink, so that the sandwich sits on the rim of the glass. Enjoy your Fluffernutter Irish Coffee!

Notes

  • Choose an Irish coffee glass with an 8-ounce capacity or larger for this recipe.
