The Rum and Dulce cocktail is sweet, creamy and rich

Sweet tooth? This creamy combo of rum and dulce de leche will hit the spot.

About the cocktail

Long ago, some genius figured out that with just milk, sugar and time, they could make a rich caramel sauce that we now know as dulce de leche. If we knew who invented it, we’d be putting up a statue – instead, we’re just going to say thank you and make one of the best dessert-style cocktails going around: the Rum and Dulce.

If you’ve never had dulce de leche before, think of it like a silky, spreadable butterscotch or milky caramel sauce. That sweet richness is the base of our Rum and Dulce cocktail, backed up by the brown-sugar notes of dark rum, the sweet toffee flavours of butterscotch schnapps (or Frangelico, if you want a nutty alternative), a little cream and a touch of lemon to keep it from becoming cloying. The result is a creamy, velvety cocktail that wields a one-two punch of caramel and butterscotch flavours that should more than do the job for sweet tooths and dessert lovers.

Speaking of desserts, we’d love to see a Rum and Dulce sub in for post-dinner sweets at a dinner party, although it would certainly slot right in beside some biscotti, tiramisu, chocolate cake, shortbread, pavlova, Christmas cake, sticky date pudding and just about any other sweet treat you like.

The Rum & Dulce is a cocktail that can stand in for dessert
Dipping a spoon into a Rum and Dulce cocktail, garnished with chocolate shavings

Ingredients

  • 30mL dulce de leche (see method)
  • 15mL dark rum
  • 15mL butterscotch schnapps or Frangelico
  • 30mL cream
  • 1 tsp lemon juice
  • Garnish: chocolate shavings
  • Glass: coupe or footed cocktail glass

Method

  1. If you’re making your own dulce de leche, you’ll need to start this recipe ahead of time. Place a tin of sweetened condensed milk in a pot of boiling water and simmer gently for three hours, checking there’s enough water in the pot throughout this time. This will leave you with dulce de leche in the can – leave it to fully cool before opening  
  2. Once cooled, combine all ingredients in a cocktail shaker with ice
  3. Shake until the outside of the tin is frosty
  4. Fine strain the mix into the glass
  5. Garnish by grating chocolate over the top – a microplane is perfect

Dan’s top tips

  • You should be able to find ready-made dulce de leche at the supermarket or specialty grocery store. But if you want to walk the extra mile and make your own at home, follow our method above – the results are fabulous and the process is super simple. You just need to start it at least four hours before you need to use it, but you could even prep it the day before, too. 
  • Classic dulce de leche calls for milk and sugar to be constantly stirred in a saucepan over a low heat for a couple of hours. We reckon our shortcut option is much easier, and the results are just as good as the traditional. 
  • As we mentioned, that butterscotch schnapps can be replaced by Frangelico, the much-loved hazelnut liqueur. And if you fancy changing the flavour profile further, feel free to sub in other sweet or nutty liqueurs once you’ve mastered the basics of this recipe and where your tastes lie.
  • As for the shaved chocolate garnish, feel free to use your favourite chocolate here, but we think a quality milk or dark chocolate is perfect.
Frequently asked questions (FAQs)
  1. What is dulce de leche? 
    Dulce de leche is a creamy caramel sauce. Our shortcut to making it is by heating milk and sugar over a long period of time until it becomes rich and concentrated.

  2. What's the best rum to use in a Rum & Dulce?  
    We’re not too picky with the specific rum here, but you’ll want to use a dark rum. A pot still or solera style will be the most appropriate, but use what you have.
