Step 1

With a handheld or stand mixer fitted with a whisk or paddle attachment beat butter on medium speed until soft for about 2-3 minutes. Add the melted chocolate and mix until creamy for about 1 minute. Add the rum and mix on low speed until well combined and smooth.

Step 2

Cool for about 5-10 minutes in the freezer or until firm enough to scoop with an ice cream scoop. You don't want them to get too hard either. The time they need to firm up will depend on how warm the chocolate was when you add it and which chocolate you used.

Step 3

Roll the truffles quickly into balls. Don’t roll for too long or the truffles will begin to melt in your hands. Cool for about 1 hour in the fridge, or 10-15 minutes in the freezer if you want to speed up the process.

Step 4

Dip the truffles in melted chocolate and let dry in the fridge for about 10-15 minutes. Dust with or roll in cocoa before serving. Store leftovers in the refrigerator for up to 2 weeks.
