This is a family favorite that my mom used to make, although she used twice the amount of rum that the recipe called for.......which is why it was the family favorite. The recipe uses a 1/4 cup of rum, but you can add more depending on taste. If you find the dough is a bit too wet to roll, you can put the mixture in the fridge 15 minutes to harden.
Mix all ingredients together in a large bowl until combined. Use a tablespoon to portion the dough and roll into balls then roll in icing sugar to coat.
These hold best in the fridge or can last in the freezer for months.
