No-Bake Chocolate Fudge Slice is a classic homemade treat that comes together with just a few simple pantry staples and no oven required. Made with crushed biscuits, cocoa, and butter, it has a rich chocolate flavour and a wonderfully fudgy texture that’s hard to resist.
This is the sort of slice that’s perfect for lunchboxes, shared morning teas, or keeping in the fridge for an easy sweet treat. It’s quick to prepare, easy to make ahead, and always a popular favourite.
Where this classic chocolate slice recipe came from
Originally this appeared in a fundraising cook book so unsure where the original recipe is from but it is a classic recipe for sure. You always know a recipe is a favourite when the page is covered in chocolate!
In fact I am sure some of the best recipes around have been handed down and appear in school fundraising cook books all over the world!
Who really owns a recipe?
It brings me onto an interesting point, the origins of recipes. I often joke that there are surely only so many ways to make say an Afghan biscuit for example – it is hard in some instances to claim a recipe as completely your own.
Often when we think a recipe is our own version a quick google will show you that it or a close variation already exists.
I always try and credit the original recipe ‘owner’ where possible, but often if I am going to share a recipe I will look it up online and find the recipe exists in many other places so it is a tricky business.
What I do work on is adapting it to suit my cooking style and using my own words and methods.
How to make this chocolate fudge slice your own
Onto this recipe for No Bake Chocolate Fudge Slice, there are only a handful of ingredients and it is a very versatile.
My friend jazzed it up with a gorgeous sprinkling of cranberries and pistachios, but you could easily use cranberries or almonds, it definitely lifts the basic recipe.
Also the original version called for coconut and sultanas, but in the slice I tasted there were neither so you can absolutely make this one your own.
Which biscuits and topping work best?
You can either use Malt biscuits or Super Wines, the Malt seems to give it a more fudgy finish, but either is just lovely. I recommend blitzing the biscuits up as finely as you can, this seems to make the finished slice more moist.
So even finer than I have done in my images. I used melted chocolate in this version but I think my basic chocolate icing would be just as delicious – if not more so! I have included instructions for both below.
If your chocolate topping is a bit firm or difficult to cut neatly, I’ve shared some simple tips in my no bake slice troubleshooting guide.

I used to make this for my two daughters , (now both in their 50’s) but always wondered about the egg being uncooked.
Could you use marshmallows instead of raw egg or not.
Just made some today for hubby and me, but it is VERY sweet, so cut it in to pieces no wider than my little finger, and about as long, as I don’t really need all that sweetness now at my age!!!! LOL!!
justamumnz says
The egg is somewhat cooked as it is placed in hot ingredients. I have not tested with any other ingredients sorry, I would imagine marshmallows would make it much sweeter again.

Hi Anna, I can tell you that this recipe is a old NZ favourite that has been around for years. I’m 55 and it was my favourite that Nana made especially for me when I was a kid. It was (and may still be) found on the back of the ‘Bournville Cocoa Powder’ packet and I had to look it up because I can’t find the old packet that I used to keep for the recipe. In NZ (sorry if you know this but I can’t see what country you are in) we always called this Fudge Slice or Fudge Cake – the Hedgehog slice name is Australian for a similar slice. The biscuits used were always ‘Round Wine’ biscuits so I suspect that the malt biscuits may be a tweek that makes it get a flavour a little similar to NZ lolly cake. A good tweak, I’d say. Cheers Deb.
