Fifteens Tray Bake

May 22, 2013

I had these recently at an afternoon tea and my oh my it was love at first bite! I recall having these years ago but had no idea what they where called. I knew I had to find the recipe and recreate it. It turns out they are a popular tray bake from Northern Ireland called Fifteens. The traditional recipe calls for fifteen of each ingredient hence the name. It is far too easy to make and no baking is required. I fear the ease of this recipe may be a very bad thing for my thighs!!



15 Digestive Biscuits (I think Graham’s Crackers for US readers are similar to Digestive Biscuits)

15 Marshmallows

15 Glace Cherries

150ml Condensed Milk

Coconut Flakes to coat

Fifteen's Tray Bake


Chop up the Marshmallows and Cherries and place in a bowl.

Add the crushed biscuits to the bowl ( to crush the biscuits finely use a food processor or place the biscuits in a bag and crush them with a rolling pin/mallet)

Pour in the condensed milk

Mix everything together well, it looks a bit odd at this stage but it will work out ok

Fifteen's Tray Bake

Sprinkle some coconut flakes onto foil

Fifteens Tray Bake

Place the mixture on the foil and roll out into a log shape

Fifteens Tray Bake

Chill in the fridge for 2-4 hours or even better overnight

Unwrap from the foil slice or cut into small squares and enjoy!

The above version is made using mini marshmallows and cut into bite size pieces which is great for parties!

(You could also put the mix in a tray cover with melted chocolate, chill and cut into small squares but they are very sweet as they are so I prefer this traditional version)

    Oh my, they look very moreish! I could probably make these with gluten-free digestives….but should I risk having such yumminess in the house?? 🙂

    These sound fantastic!. I am afraid though that if I made them for friends that the grand kids would find them first. Oh, who am I kidding I’d eat them first. They sound pretty easy to prepare. This could be something that my oldest grand daughter could learn to make as a special treat for her younger brothers and sisters. At twelve she loves to make treats for them. She claims it’s her job as a big sister. I’m not going to stop her, I get to eat to.

      These are fantastic and so easy, too easy in fact! Anytime I have made them for work events they go real quick 😉

    I used to make something very similar using chopped dates instead of cherries. It also had chopped walnuts. We let it chill wrapped in the log overnight. Then we would slice it and serve it topped with whipped cream. Yummy!

      I love dates and walnuts might have to give it a try 😉

    Boy am I pleased to have stumbled upon your site and this recipe. I love how simple it is. Do you have any recommendations on what I could use instead of coconut flakes? Do you think melted chocolate would work? Also is there an alternative to the condensed milk?
    Thanks for this recipe, I cant wait to try it out!

    • Reply Mary March 5, 2014 at 7:55 pm

      Maybe try flaked almonds,any type of nuts,dried fruits or chocolate chips? I think melted chocolate would be good as a topping only for this recipe but that would make it very sweet. When you say alternative to condensed milk do you mean you want to take the condensed milk out of the recipe or a DIY version of condensed milk if you did not have available say?

        Sorry, I meant to take it out completely and replace with something else to bind in together. I went out and bought the ingredients today. But instead of glacier cherries we’ve gone for a dried fruit mix and chopped nuts. My little girl is super excited to get making this. Im not sure if she’ll be happy about the waiting to eat it though! Thank you for sharing your recipe. I’ll let you know how it turned out!

          Well let me know how you get on? I was going to say cream of coconut would work well as a sub for condensed milk but I am guessing you are not keen on coconut??
          Soya/Rice Milk could also be used to make a condensed milk substitute its a good dairy free alternative.

    Hi! I love this recipe and grew up eating them in Scotland! 🙂 A variation that we have is we use icing/powdered sugar instead of the coconut. 🙂 I now live in California and make them here.

      Hi Susan, glad you are enjoying a taste of home in California 🙂

    They look scrumptious – like a variation of Rocky Road or a refrigerator cake. So easy to make and no cooking required. Actually, does making this mean that I am reducing my carbon footprint? A fine excuse to make it!

      These are always super popular when I make them to take to work events, parties etc 😉

    My kids don’t like glazed cherries, so I used mint Aero instead! They didn’t stay in the tin too long!

    • Reply Mary March 5, 2015 at 9:38 pm

      Sounds great will have to give that a try love mint Aero 🙂
