This recipe for Nanna’s Marshmallow Slice is such a popular one, a classic recipe that many will recall from their childhood!
My husbands Nanna recently passed away so he was keen for me to make a recipe he remembers from when he was a child – it was something I have never made before so I was delighted to give it a try. It is always hard to live up to the memories of childhood and he claims Nanna’s looked bigger and had a white and a pink layer but I assured him I followed the recipe! lol However according to him it turned out pretty well and tastes the same .
The recipe I was given calls this Marshmallow Biscuit – but I have called it a slice here to avoid confusion! The base is a lovely light shortcake that is super simple to make and bake, I like to make it nice and thick to ensure it matches up to the big topping!
So often memories of our childhoods are around a special occasion, or a special food and this slice was something his Nanna would make up when they came over to visit or stay – if you are not a fan of sugar then this is definitely not the recipe for you! But as an occasional treat this is perfect. The kids loved it today – and I was surprised at how easy it was. So fun making marshmallow from a liquid!
The original recipe calls for the base to be made in two sandwich tins (which Google tells me are round tins?) but I made it in a square 25cm tin and it came out well – the base is quite thick but it is a lovely buttery shortcake which is a nice complement to the marshmallow topping. If you do choose to make it in two tins it will be thinner but you can still use the topping for just one (so will need two lots of marshmallow – you could always freeze one base if not needed right away)
You can cook the base ahead of time as it has to cool – I added strawberry jam between the layers, raspberry jam would be nice too.
Nanna's Marshmallow Slice
Ingredients
- BASE
- 115 g butter (4 oz)
- 115 g sugar (4 oz)
- 1 tsp vanilla essence
- 1 Egg
- 225g Flour (8 oz)
- 1 tsp baking powder
- MARSHMALLOW
- 1 packet jelly crystals (I used strawberry - 85g)
- 1 TBSP Gelatine
- 2 Cups Water
- 1 Cup Sugar

This was so fun to make and I am looking forward to making it again – you could even make it with different flavoured jelly for a different occasion – or go double layered on the topping if you felt extra fancy with two different colours setting one first then adding another – would be tall though! 🙂

Oooh!! I remember getting this from the local bakery when I was little and I’m fairly sure it had the jam in between two layers of shortcake and then the marshmallow directly on top of the top shortcake layer. Maybe that’s why the original recipe said to bake in 2 sandwich tins? Regardless, I’m going to give it a go as you’ve made it as it looks delicious!!
Rachel says
This recipe came out perfectly. How long will it last for? Do you keep it in the fridge or in the pantry?
justamumnz says
Store this one in the fridge.
Sheryl says
I made it in a 30cm x 20cm Swiss roll tin and only about half the marshmallow fitted. Will use a deeper tin next time. It’s delicious!
Marissa Springhall says
Absolutely beautiful , takes me right back to my childhood, turned out perfect. Kids looved it
Gineke says

You are welcome, I am so pleased you enjoyed it.
Del says
Hi, this looks amazing! I was thinking of making it for a school bake sale, and wondered if I can make it up the night before? Will this keep well in a sealed container?
Thanks 🙂
justamumnz says
Yes the night before is fine. Keep it in the refrigerator to set until you want to slice it the next day.

Saw this recipe and knew I had to try it for my Minis, easy to follow recipe and instructions. My only variations were to add some lemon rind to the biscuit base and chocolate ganache on top, as it reminded me of a Wagon Wheel! It’s delicious.
justamumnz says
Awesome! What great additions too.
Carol says
My grandmother used to make this. It was a family favourite too, and she always sprinkled dessicated coconut on top. I like your idea of a layer of jam.
justamumnz says
Coconut would be a lovely edition Carol. Thank you for stopping by the page 🙂
Tania says
I love this, it looks delish and I especially love how it’s a beloved family recipe 🙂
Ganga says
Great recipe. Thank you for sharing. I made just the marshmellow part in 3 layers and poured it into pudding cups to have it as dessert. Family really liked it. I personally think it needs to be more airy though. How would I achieve that you think?
justamumnz says
Hi what a great idea making it in pudding cups! The longer you beat it for the more airy it becomes I find, let me know if that helps next time. You sometimes need to beat it for ages. 🙂

This is awesome!!! I made this marshmallow using a low sugar crystal packet, and subbed stevia for the sugar for a healthy spin – HUGE success and so light and fluffy!! this is a keeper thank you so much for sharing!
justamumnz says
That is so cool Sally! I am pleased you were able to get this to be a low sugar option 🙂 Thanks for letting me know about the alterations – and best of al that they worked!! 😀
Michelle says
l have made this with yellow colouring and l think a pineapple or lemon jelly for Daffodil day it was a hit with the kids at school who had to take along food with yellow in
It is a great recipe and loved by our family might have to make again soon
justamumnz says
What a great idea!! I never considered it with other flavours but I am going to try that – my favourite colour is yellow!!! 😀
maureen says
Oh how wonderful….I used to make marshmallow slice with this recipe made with jelly when my children were younger, but I lost the recipe and have been trying to find it ever since. I am wrapped that I have found it again through you. My mum used to make it. Sooooo many wonderful memories of days home bye. Thank you thank you thank you.
justamumnz says
Maureen you are so welcome! I am sure Doug’s Nana would have been pleased to know her recipe continuing to make people happy 🙂 Enjoy!
Jodie@Fresh Home Cook says
Wow Anna this looks just gorgeous! My little people (& this big one) will go crazy for this – anything with that much marshmallow had gotta be sensational! 🙂
Jessica says
That looks like it would just melt in your mouth..and for some reason I love food that does that lol. Im weird, yes I know! But like peanut butter melt-aways and all things cool whip, they are just so great when they are so light and fluffy that they just melt and you dont have to chew! Maybe I am a lazy eater haha. Thanks for linking up at Totally Terrific Tuesday. Make sure you come back Monday night at 10pm to link up any new posts!!

Kim @ This Ole Mom says
Hello! I have never heard of this before but it looks really good. I was wondering how much marshmallow do you use? I would love to try to make it. Thank you for sharing it with us at the Click & Chat Link Up Party!
Have a lovely week, Kim @ This ole Mom
justamumnz says
Hi Kim, the jelly, gelatine, sugar & water make the marshmallow! Once the mixture cools you beat it for about five minutes and it turns the liquid into marshmallow – quite amazing! It makes about 3-4 cups or so of marshmallow gooey goodness – any othe questions please ask! 🙂
