Fifteens: A Traditional Irish Dessert

Fifteens: A Traditional Irish Dessert

I got this recipe from my friend who grew up in Donegal, Ireland but now lives the sweet life in Spain. Fifteens are a pretty traditional Irish dessert. But these have a fun twist.

Traditionally there’s a bunch of dried fruit and such in fifteens but her family is “not about that”. So are these traditional fifteens? Technically no. But are they delicious? Yes. And do they authentically come from Northern Ireland? YES. So, don’t @ me.

But are these also probably better than your traditional fifteens? YES. Why? Because we skip all the candied fruit and exchange it for chocolate. And chocolate is always best.

What You’re Going to Need

If you’re not in the UK, which most of you guys aren’t, finding some of these things are hard. So I’m including links to everything you need PLUS some substitutions for your convenience.

Digestive Biscuits. Contrary to what I thought, these are not probiotic or laxative filled biscuits. If you ask me calling them Digestive Biscuits seems a bit like false advertising in that case but what does I know? I’m from across the pond.

Cost Plus World Market has a bunch of these things if you’re looking to get the things in person.

BUT! If you’re a normal 20 something year old order them online here. I have also been informed by my friend that graham crackers make a good substitute.

Cadbury Crunchie Bars – Honestly the closest thing I can think of to theses are Butterfingers. They have a similar texture but they’re different in taste. I would still suggest you get them here instead.

Mix, mix, mix.

Mars Bars – You can replace with Milky Ways but honestly, I don’t think Milky Ways are as good as Mars Bars. So I’d suggest getting yourself some Mars Bars if possible.

*Update: some people have been telling me that they are the same thing. I still STRONGLY disagree*

Malteasers – These are easily replaced by Whoppers in the US.

Silicone baking mats are important for the planet and to roll and chill these fifteens.
Food Processor – Food processors are super useful and if you wanna be all twinsie with me you can get this cute mini Food Processor I have because I was too cheap to buy a full size one. (Hey, it still gets the job done).

Recipe Tips…

This is how you roll as an eco-friendly person
  1. Make sure you don’t add too much sweetened condensed milk. Add it slowly and you may need a little less or a little more depending on the humidity level where you live.
  2. Your biscuit mix should be wet enough to stick together but not so wet that it’s sticky and sloppy.
  3. The desiccated coconut is not 100% necessary. BUT! Without it, your fifteens will just look like a sad, brown, sticky…..biscuit. Coconut gives it a slightly more aesthetic appeal.
  4. To get the Pink Coconut, I used regular shredded coconut and added it plus a quarter cup of pink sanding sugar and chopped it into desiccated coconut size in my food processor.
  5. Make sure these chill WELL. If they don’t have plenty of time to solidify, they’re going to crumble like crazy.
  6. Finally, consider using a sharp serrated knife. Those Malteasers/Whoppers are freaking hard to cut through.
