  • Rocks glass
  • Bar spoon


  • 2 ounces peanut butter whiskey
  • 3-4 dashes angostura bitters
  • 1 large cube
  • Orange twist for garnish, optional
  • Cocktail cherry for garnish, optional


  • Pour the peanut butter whiskey into a rocks glass. Add the dashes of bitters.
  • Place the large ice cube in the glass. Stir until chilled and the ice starts to melt, about 15-20 stirs.
  • If desired, garnish with an orange twist and cherry. Enjoy!



  • While you can certainly use standard ice cubes, I prefer to make an old fashioned with one large ice cube. This type of ice cube melts more slowly to ensure your drink doesn't get too watered down.
  • That said, if the peanut butter whiskey is too sweet for your taste, you can add a bar spoon of water to the mixture. I love it as is, but we all have different palates.
  • Feel free to experiment with the bitters. To keep it simple, I used angostura bitters, but there are so many bitter flavors that would be wonderful. Think orange, chocolate or ginger!
  • To make the orange peel garnish, cut off the bottom of the orange to give it stability. Then, use a paring knife to cut the orange about 2 inches wide and all the way down the length of the fruit. Try to make the cut shallow enough that it's pith rather than fruit on the other side of the peel.
