FIFTEENS RECIPE
Hello, Eats with Ash friends. The other week, I saw a recipe on Instagram for something called “Irish Fifteens” that looked very similar to New Zealand’s Lolly Cake, so I thought I would give it a go. A quick disclaimer before we start, though – this didn’t turn out as well as I’d hoped. I’ve forgotten the name of the Instagram user that I saw make this, but this recipe is adapted from that, FYI.
Fifteens are a Northern-Irish no-bake tray slice (even though you don’t actually need a tray). I don’t have a lollycake recipe on this blog, but I do have one on my main blog, asheycakes “here“.
Ingredients/What You Will Need
- 400 grams Biscoff Biscuits
- A can of condensed milk
- 250 grams of mini marshmallows
- 250 grams of Malteasers
- 120 grams of butter (fully melted)
- Dessicated coconut
- Rolling pin (and sandwich bags) or a blender/food processor
- Bowl
- Mixing spoon
- Glad Wrap
Method
- Crush Biscoff biscuits into tiny pieces (I did this by smashing them with a rolling pin in sandwich bags), but you could just blend them to a desired consistency.
- Place crushed biscuits into a bowl. Melt the butter in the microwave with the condensed milk (this is where I went wrong – I didn’t warm the condensed milk). Then pour over biscuits and mix.
- Add in marshmallows, Malteasers, and any other things you might be adding in (i.e., glace cherries)
- Roll the mixture out into a log and cover with dessicated coconut.
- Wrap the log in Glad Wrap and place it in the fridge overnight (or until set). For me, the text didn’t quite work, so I just put it into a loaf tin and added coconut, then wrapped it up (we MacGyver-ed it).
- Once set, slice and enjoy!
