This Jelly Slice is a delicious classic recipe that you will love! A few tweaks to the original recipe make it better than ever!

There have been many unexpected blessings come my way since starting this blog, but one of my favourite ones is when people share with me their favourite family recipe.
I have seen photos of this particular recipe around but didn’t know how it was made, but a lovely Mum at my music group offered to share her husbands Nanas recipe and it is just so special to me rather than whipping up a random recipe! So thank you Rachel, now I can share it with the Just a Mum family too!
So with some trepidation I set about making this recipe – seemed easy enough – surely I could pull it off and I was delighted with the result. It looks gorgeous and so simple to make! I have decided if a recipe calls for a biscuit and butter base you can’t go wrong as its bound to taste delicious!
You could choose almost any jelly to go with this, don’t feel you have to do strawberry as I have done here, try grape, raspberry, blackberry, anything sweet and delicious that you like the taste of. The slice itself is surprisingly not too sweet so is a lovely and light treat.
The only warning is it is one of those recipes that does need a little time in between each layer to set so allow a couple of hours start to finish, but the layers themselves take less than a few minutes each to whip up so get about doing other stuff while it does its thing.
Here is the recipe, thanks again to the gorgeous Rachel, this would make a lovely slice to take to any occasion. We have doubled the Jelly here by using two packets of jelly – feel free to use just one if you wanted a thinner layer – and halve the boiling water to just 1 1/2 Cups.
If you love working with Jelly these Jelly Pinwheels are amazing, a little bit of kitchen magic, kids love these
Jelly Roll Ups – Jello Pinwheels
Many people assume this will be rich and overly sweet like a cheesecake, I assure you it is not. It is light and perfectly flavoured! I love adding lemon zest to the bottom two layers to add even more depth to the flavours.
Onto the recipe I hope you enjoy this amazing Jelly Slice.
Jelly Slice
Delicious and so pretty, this Jelly Slice is just lovely
Ingredients
- 2x Packets Jelly, 85 gram packets
- 3 Cups Boiling Water (750 mls)
- 1 Packet 250g Superwines, or similar plain sweet biscuit
- 160 grams melted Butter
- (Optional 1/4 cup chopped nuts, 30 grams)
- 2 teaspoons Gelatine
- 1/2 Cup Boiling Water (125 mls)
- 1 Tin Sweetened Condensed Milk, 395 grams
- Juice from 1 Lemon (approx. 2-3 Tablespoons)
- OPTIONAL
- I add lemon zest to both the biscuit base and the condensed milk centre. Try a tablespoon or two in either or both!
Instructions
- Prepare 25 x 25 slice tin with baking paper and set aside - I lightly spray my tin first so paper sticks!
- Make up both jellies with 3 cups of boiling water and pop into fridge to cool.
- Blitz biscuits in food processor (or by hand if need be).
- Combine melted butter and chopped nuts or lemon zest if using
- Tip into slice tin and firmly press down until evenly spread.
- Pop into the fridge to chill for 30 minutes.
- In a medium bowl add gelatine and 1/2 cup boiling water and mix well until all gelatine is dissolved.
- Add to this the condensed milk and lemon and zest if using and mix well.
- Pour over the chilled base and set aside in the fridge for 30-40 minutes until completely chilled and setting.
- Once jelly has cooled but not set pour over the milky layer over the back of a large spoon (so to not disturb the condensed milk layer) and pop in the fridge until the jelly has set
- Once set - remove from fridge for 20-30 minutes and then run your large sharp knife under hot water - then dry - then slice the one edges off the slice first.
- Using a long knife (heating & drying as need be between slices) cut down into the square and apply pressure to cut through biscuit layer. Then slice into squares or smaller pieces.
- Keep the slice in an airtight container in the fridge.
- Enjoy!

Su says
Could you tell me how much condensed milk to use? A small it or large tin?
Hope to try this recipe tomorrow
Many thanks
Suz
justamumnz says
1 tin of condensed milk is 395 grams.
Dianne says
Hi Anna…made this today but the condensed milk layer was quite flat and rubbery. Should it be beaten or just combined as not quite sure. Otherwise it was yummy!!
justamumnz says
I am sorry that happened, it should be light. I wonder if a touch too much gelatin?
First time baker during covid says
Hi, would a 2.5cm depth tray be ok for this recipe? I have a tray that measures 30cm x 20cm x 2.5cm and was wondering if this slice would fit?
justamumnz says
Sorry I don’t think it would work, the tray you have is not deep enough.
Naomi Rincon says
This happened to me too, to fix it I just microwaved it in 20 second intervals and mixed really well until melted
Jane says
Made this today for my Good Bitches Baking bake so it’ll go to families who don’t get many treats. I’m sure they’ll love it and it’ll bring a smile to people’s faces.
justamumnz says
Such a fabulous charity, good on you!
Trish Campbell says
A bit late replying but to let you know I did just beat/whip one jelly to put on top of a set jelly of a different colour and it worked. The whipped jelly was quite fluffy and people went back for seconds, even the adults!
I used different colours but next time will try two jellies of the same colour.
Trish Campbell says
I’m thinking of one jelly set as usual an the “whipped” jelly on top, different colours.
What do you think?
justamumnz says
I know you can whip jelly with evaporated milk but I’m not sure what whipping an almost set jelly would do. Keen to hear how you get on.
Trish Campbell says
Hi Anna,
I love this recipe.
Another jelly related question – have you ever whipped an almost set jelly (without the addition of evaporated milk) and would the jelly froth up okay? Wanting to try this today for Christmas BBQ on Saturday.
Thankyou
Trish
justamumnz says
I haven’t tried either version sorry.
Syberyah says
Why do you need the jell-o/jelly and the gelatine? Are those not the same thing? I’m American so maybe gelatine/jelly is something a little bit different in Australia or New Zealand or wherever you are. I want to make this recipe but I don’t want to screw it up, lol.
justamumnz says
So jelly/jell-o is for the top layer, it’s a sweet strawberry jello. Then the middle uses gelatine, it’s a flavourless powder that helps the middle layer set. So you use both for different purposes. Have a read through of the method which might help make it clearer.
Donna Jones says
This is the best recipe ever, my daughter now 17, does not eat jelly but has been making this every Xmas for a few years now and eats it, her Nana makes a large version of it for family celebrations and calls it cheesecake
Heather McBride says
Delicious…made today and my husband has just informed me that Jelly Slice is probably an endangered species!!!! He’s devoured 3 pieces already, and our daughter, who I actually made it for, loved it too!! Thank you.
justamumnz says
Ha ha yay! I am so glad you and your family liked it! It is lovely as not too sweet so very easy to devour I agree 😀 Anna
Storme says
Making this for the first time today for a shared supper tomorrow night! 🙂
justamumnz says
Great Storme – it is so easy and looks lovely! Best of all it is not sickly sweet but quite light so people enjoy that aspect too 🙂
Storme says
Its awesome! The layers all stick together really well. Very light and moreish 😀
Kids were all scrounging round for off cuts, am thinking next time I’ll use more lemon juice, maybe some rind and lemon jelly on top. Or the strawberry slices in strawberry jelly 🙂
justamumnz says
Great ideas! I am going to make this for xmas day and going to add strawberry halves to it as well 🙂
Lucy says
Isn’t this a lovely recipe? Sliced strawberries layered on the condensed milk layer and then strawberry jelly poured over looks and tastes wonderful as does pineapple rings on top of the set condensed milk layer and then pour over a pineapple jelly. I’m thinking I might have to make one for the family as part of our Christmas dessert! 🙂
justamumnz says
I just saw the strawberry idea today Lucy! I am definitely going to try that as it looks so beautiful. And Pineapple, what a clever idea! Thank you so much for popping by, I am inspired now 🙂
mIGLE says
I just tried making this, and it went really gloopy, I felt that it was far too much gelatine, it’s ruined now. NOT GOOD
justamumnz says
I’m sorry to hear that, I’ve made this many times and it’s worked well. Did the gelatin completely dissolve for you before it was added?
