Print Recipe



  • 3 cups granulated sugar 600 grams
  • ¾ cup salted butter 170 grams (1½ sticks)
  • 5 ounces evaporated milk 142 grams (or ⅔ cup (151 grams) of heavy cream - SEE NOTES!)
  • 12 ounces white chocolate chips 340 grams
  • 7 ounces marshmallow creme 198 grams
  • ¼ cup spiced rum 57 grams
  • ½ cup chopped walnuts 57 grams


  • Prepare a 9x13 or 8x8-inch baking pan and line it with parchment paper. Leave a small amount of excess paper on the sides so you can easily remove the fudge after it sets. Set the pan aside.
  • In a medium saucepan set over medium heat, combine the sugar with the butter and milk. Stir or whisk until it begins to boil, then continue mixing it while it boils. Once it begins to “foam”, let it continue to boil for about 3-4 minutes. Remove the pan from the stove, and add in the chips and marshmallow creme. Quickly stir the mixture until the chips have melted with the creme. Using a rubber spatula, or wooden spoon, add the rum and the nuts into the fudge mixture and gently stir it in to combine it all together.
    3 cups granulated sugar, ¾ cup salted butter, 5 ounces evaporated milk, 12 ounces white chocolate chips, 7 ounces marshmallow creme, ¼ cup spiced rum, ½ cup chopped walnuts
  • Pour the fudge mixture into the prepared pan, and spread it evenly. Allow the mixture to cool until it is set, about 2 hours.


  • Cut into 1-inch squares and serve. To prevent the fudge from drying out, keep it covered with saran wrap or in a sealed container.
  • For an extra creamy (and very rich) fudge, you can substitute heavy cream for the evaporated milk. The fudge tastes the same, but the cream is a little bit sweeter. If using cream, be sure to keep the fudge refrigerated or it will become slightly soft.
Storage: Store white chocolate rum fudge in an airtight container at room temperature for up to 2 weeks, in the refrigerator for up to 1 month, or in the freezer for up to 3 months.
