Cuisine Danish


  • 850-900 g cake leftovers (chocolate cake is a must and also like a roulade with some delicious filling but otherwise, there is a free choice on cakes)
  • 1 tsp. vanilla sugar
  • 4 tbsp. cocoa powder
  • 1 tbsp. romessens
  • ½ dl cocoa milk
  • 1½ -1¾ dl raspberry jam (150 to 200 ml)
  • 150-160 g crumbs (or coconut flakes or something similar. Cocoa nibs are also optional)


  • Cut any large pieces of cake into uniform sizes and add them to a mixing bowl. Stir the leftover pieces until you get one whole dough.
  • Add rum essence and vanilla sugar to the dough and make sure it is fully mixed in.
  • Put the dough in the fridge for a few hours – preferably more. It should start off soft and then reach a firmer consistency after being chilled. It is advisable to make the rum balls the next day.
  • Test the dough by taking a piece and rolling it in crumbs or coconut flakes to see if you have the right consistency. If it is too hard, add a little more cocoa milk or raspberry jam. If it is too soft, well, then you are a little on it, unless you have more cake leftovers.
  • After testing your dough, roll the dough into balls of a size that suits you.
  • Roll the rum balls in crumbs, coconut flour, cocoa nibs, or whatever you have chosen.
  • Keep the rum balls in the fridge until they are ready to be served.


Did you know that rum balls are also called truffles? (you can probably also see a similarity between the truffle and the rum ball). They are also called sputnik. There are many names for the dessert. 

Additional Information on the Romkugler Recipe

The romkugler is a creation of Danish bakers. Back then, there was a rising problem of leftover cakes and pastries. Given that the cakes and pastries would not last the next day, the bakers came up with a solution. Using cocoa powder and some rum, they mixed together with the leftovers until they got a sticky dough. The dough was then decorated with coconut flakes and chocolate sprinkles and thus the Romkugler recipe is born.

As the dessert doesn’t require any cooking and makes for an easy snack, you can make the rum balls any size you want. You can also test out different cake flavors that pair well with cocoa and rum.
