This is an oldie but a goodie. This Marshmallow Fudge Slice is simple but so fun to make!
Some of the most popular recipes on my blog are the classic ones, recipes that Grandma used to make with total ease when we visited, or ones that have appeared in tea rooms ever since I was little.
This recipe is one that is often mentioned to me when I share my Marshmallow Shortbread recipe, this one is just as simple and definitely just as delicious.
I have been having so much fun baking recently as finally after many years my 17 year old oven has been retired!! It did really well, in fact despite having no timer or light, and the inability for the door to fully close it is responsible for all of my recipes so far on this blog! It has done a great job of baking for years for my family despite its failings. So a new oven needed a new recipe to test!
As with most old recipes this one is modified from the Girls & Boys Rally book, which is a lovely collection of recipes sent in by ladies up and down the country many years ago. They tend to be easy and delicious. But with many old recipes they include the bare minimum of details as to how to actually cook the thing!
So it is my job to flesh out the details and method for you to make it nice and easy to replicate. The most tricky bit honestly was making the marshmallow and to be honest its pretty easy. BUT I did burn the first lot! So my advice is to follow instructions I give below but watch the boiling of the gelatine and sugar.
If you love Marshmallow slices many of you might remember this version made with Jelly, my husbands Nannas Marshmallow Slice
Marshmallow seems to be a treat I cannot get enough of so do check out these recipes also using a bag of marshmallows.

And now onto the recipe, you will love this special Marshmallow Fudge Slice, let me know in the comments below if you make it.
Thank you so much for stopping by to check out this recipe! It is an old classic that will go down a treat with family and friends. It is best eaten on the day of baking, but honestly it was still lovely the second day.

Oh my goodnes…. My Dad used to make this – then we lost his recipe book, so it’s been 10 years since I’ve tried it! I am so excited to try and make this and present it to him when we go and see him next. Quick question – does the base need to be cold before I add the marshmellow, or just cool to the touch?
Sorry if someone has already asked this…. but is this freezable?
I haven’t tested this sorry. My first thought is maybe not as I’m not sure how it would thaw but I haven’t tried sorry!
My kids loved this! made yesterday and added a drop of red food colouring to gelatine mix and it came out a perfect pink (my kids only like the pink marshmellows!! lol)
My only question was around the part where it says: set your timer to 5mins, heat mix to boil but it doesn’t say when to turn on your timer…I wasn’t sure if I turned it on once I turned on the element or if I turned it on once I boiled the mix…
My marshmellow was very tacky but still turned out great!
Hi, once you put it on the element set a timer for five minutes, bring to the boil gently then remove once timer goes off 🙂

This is my favourite recipe!! So easy and a big hit with the kids ?
do you think substituting gluten free flour for flour would work as i can now buy gluten free weetbix
Hi Carol, I haven’t worked with Gluten free flour before but I believe it will work fine in this recipe. Let me know how you get on. Anna
Could I leave out the coconut or would it be too moist then?
Why I ask is hubby can’t have coconut.
You will need to amend the recipe somehow. Alternatively try my recipe called Nannas Marshmallow Slice, it has a shortbread base

Hi there love this recipe, my mum used to make it for special occasions and I have continued the tradition. I have an alternative way to make the marshmallow if you would like to try it.
In a bowl:
Dissolve 2 tablespoons of gelatine in 1 cup of boiling water, add 2 cups of sugar and beat with an electric mixer(the kenwood type on a stand works best) on fast speed until thick. Add 1 teaspoon vanilla essence, you can also add a few drops of food colouring if you wish. Pour over cooled base and place in fridge until set.
Thank you Shona! I will give it a try
Hi there I have made this slice twice since I found it and love it! I’m a bit confused about the amount of gelatin – 1.5 tbsp of gelatine seems like a lot is that correct? The second time I made it I stuck to that measurement but the marshmallow seemed quite dense compared to the first time. I must say though this is my first time making marshmallow so I’m still learning!!
Hi, I’m so glad you like it! The original recipe calls for 2 dessert spoons of gelatin so the equivalent is 1.5 tablespoons. 15ml tablespoons. But you can always experiment! ☺️
Hi JustaMum, I love your new oven, loved baking this slice. The marshmallow is fun to make. I remember the old Rally Cook book too! Xx
Glad you enjoyed it, thank you ☺️
