  • 15 digestive biscuits
  • 15 marshmallows
  • 15 glacé cherries, cut in half
  • about 200ml condensed milk
  • 100g desiccated coconut, to coat


  1. Crush the digestive biscuits in a food processor or in a plastic bag with a rolling pin, then put them in a large mixing bowl. Chop each marshmallow into 4 pieces and add to the bowl with the cherries and 175ml condensed milk. Mix until the ingredients are well combined and you have a sticky mixture. If it’s too dry, add a splash more condensed milk.

  2. Sprinkle most of the coconut over a large piece of cling film (or foil). Tip the mixture onto the coconut and shape into a long sausage, about 30 x 5cm. Sprinkle more coconut over the top of it and wrap the cling film tightly around, twisting the ends together. Leave in the fridge to chill for 4-6 hrs, then cut into 15 slices and serve. Will keep in the fridge for up to 1 week wrapped in cling film.

It only took me 10 minutes to make and was extremely delicious.

These did turn out well, I was happy with the result taste wise and will make again. For a harder finish I'd leave in the fridge overnight as mine was still sticky after five hours in the fridge. Also 200g is wayyyyyy too much. I used half that and it was touch much to stick with the fifteens. In future I may try putting the coconut in the mix and seeing how this effects them. My partner is a chef and from Ireland and suggested that so I can't go wrong.

I absolutely love love love fifteens!! I've made this recipe for some friends coming over on Xmas eve (I live in England now), and I'm hoping they'll love them as much as I do!

Lovely recipe! I substituted halved maltesers for the glacé cherries. I found 200g of dessicated coconut about 4x too much though - next time will try 50g to begin with!

15s! I loved these but haven't thought of them in years (I live in England now - naturally it was when I lived in NI that I had them, courtesy of a Lisburn friend). Will be making them very soon so thanks Alice for the reminder!

Food processing the digestives rather than bashing them will make it easier for the fifteens to bind together.
