This is not your ordinary Marshmallow Slice – but it still holds its place as one of my all time favourite slices! This no bake marshmallow slice is like none other.

This recipe has featured on my blog for some time but as one of my first recipes so I thought it was time to revisit it and photograph it again so you can see just how delicious and simple it is!
As you can see this is not the usual Marshmallow Slice with a lovely fluffy topping on a shortcrust base that you would expect to find. You can find that version here. This is yummy chocolately, biscuity, marshmallowy goodness with a good dollop of butter & sugar for added tastiness – you sure don’t come here for diet advice!
This recipe is delicious, easy and a great treat to take as a plate – or lets face it – to eat when the kids are in bed! I had it once at a friends birthday party and the lovely Sarah was kind enough to share this recipe her Mother had given her.
One tip I have is that I freeze my marshmallows – I pop them in the freezer a day or two before I need them. You can of course not freeze them at all and it potentially has no effect on the outcome but my hope is that the marshmallows hold their shape longer. How about you make two batches and test it out!
The recipe is so simple – crush the cookies, slice the marshmallows, melt together the rest of the ingredients and combine! The hardest part to be honest is allowing it to cool sufficiently before testing it, and this is the best lick the bowl recipe you will ever find.
So I will say here to allow to chill overnight, but honestly, you can eat this stuff with a spoon if you need!! Kids love it, but seriously I have found adults love it more!
So here is the recipe for No Bake Marshmallow Slice
No-Bake Marshmallow Slice
Delicious and decadent No Bake Marshmallow Slice
Ingredients
- 2 Packets Super Wine Biscuits (500 grams total) - a sweet tea biscuit
- 1 Tin Sweetened Condensed Milk (approx 395 grams)
- 250 grams Butter, diced
- 1 Cup Brown Sugar, packed (200 grams)
- 4 Tablespoons Cocoa Powder
- 1 teaspoon Vanilla Essence (5mls)
- 180 grams Marshmallows* Frozen is best
Instructions
- Prepare a 23-25cm slice or cake tin with cooking spray and baking paper (allows paper to stick)
- Crush the biscuits, leaving some pieces a little chunkier sized crumb, I use a food processor to make this easier.
- Using kitchen scissors or sharp knife, slice the marshmallows - I usually slice off a third then cut the remaining bit in half and set aside.
- In a large pot add the butter, condensed milk, brown sugar and cocoa and over a low heat melt until completely combined, stirring occasionally.
- Once melted add the vanilla and stir in well.
- Once the ingredients fully combined & melted, pour into this the crushed biscuits and the marshmallows – quickly combine all the ingredients.
- Spoon mixture into the lined slice tin. Firmly press down with the back of a spoon.
- Allow to set in the fridge before slicing - ideally overnight.
- Slice into squares to serve, storing in an airtight container in the fridge.
- Enjoy!

I’m in Australia and have never heard of those biscuits what other kind can I use thanks ✨🤗
justamumnz says
Arnotts Marie biscuit in Australia
Cindy Whittle says
Silly question but is the sugar supposed to be completely melted in the sauce before adding to the marshmallows and biscuits? I may need to use a darker brown sugar next time.
justamumnz says
Hi, no just so that the butter is melted through, so the usual soft brown sugar works well.
Marlene Heise says
I have just made this no-bake slice. Looking forward to eating it.
Tip: To slice marshmallows I dipped my kitchen scissors in hot water every now and then. Prevents marshmallows sticking to scissors.
Shane says
Absolutely amazing!!! Easy to make and delicious. Better than Rocky Road.
Tracy says
Great recipe but we found it a little too sweet. Can I lessen the brown sugar next time?
yebean says

Brilliant. My mouth is foaming reading this
Kelly says
Mine didnt set properly it’s been in the fridge for 15 hours and it’s still quite gooey and sticky. I’m not sure what I did wrong I followed the recipe. In fact I can never seem to get slices to set properly ?? is still very yummy tho just really messy and hard to eat
justamumnz says
I am sorry to hear that! I make this one often so I know this recipe works. I am wondering what could be causing all of your slices not to set. So a couple of ideas I have. Make sure to measure your butter (and that the scales are set right), ensure the condensed milk is full fat one, not a lite one. And also make sure you blend up your biscuits to a fine crumb. You can have a few bits a little larger but the small crumb will help absorbed the moisture. Other than those few things it is tricky for me to know without being with you. Let me know how you get on or what you think it might be. I have lots of easy no bake slices on the blog you are welcome to try. Anna

Just made this over the weekend and both my son and hubby pretty much demolished it in 2 days.
I tried making it without freezing the marshmallows and some became gooey (which was fine) but will try with frozen marshmallows next time.
I love this website-have found so many recipes to try ☺☺☺
justamumnz says
That’s great to hear!! It is still lovely with them gooey. Just so long as not so dissolved if that makes sense! Freezing just helps a little with them keeping shape. Great excuse to make it again though ☺️
justamumnz says
That’s great!! So glad you enjoyed it and great excuse to make another 🙂
Elysia says
Hi, Can you freeze this slice?
justamumnz says
Yes, no bake slices are fine to freeze, especially ones that are not iced. Simply wrap the slice in plastic wrap, then in a layer of foil and place into an airtight container in the freezer, ideally no longer than a month.
Kate says
We’re do u by super wine biscuits or what else would substitute
justamumnz says
Depends what country you are in. They are similar to arrowroot biscuits.
Liz says
This is delicious and super easy to make! My only query was cut marshmallows then freeze or would it be possible to easily cut frozen ones? I cut first just in case! Thanks for a great recipe.
justamumnz says
Good question! I just cut when frozen, they aren’t fully hard any way.
