These fun and colourful Jelly Roll-Ups are such a delicious Kiwi treat, made with simple ingredients for an easy little sweet the whole family will love.
Posted February 5, 2014, Updated December 10, 2025
I love the look of these! Such simple idea but looks so cool! The kids love them and I think they are so fun to make.
A few years back a friend of mine shared this recipe with me and while I was thinking of fun baking ideas for the kids I remembered these!
You can use any coloured Jelly (Jello) you like – the marshmallows will take on any colour you choose.
Now onto my recipe for Jelly Roll Ups!
Jelly Roll Ups - Jello Pinwheels
Such a delicious, colourful and easy treat, with only 3 ingredients!
Ingredients
- 1 packet of flavoured Jelly (3oz - 85g)
- 1/2 Cup Cold Tap Water
- 1 1/2 Cup little mini Marshmallows
Instructions
- Lightly spray an 8 or 9 inch pan square or rectangular pan with non-stick cooking spray and make sure it is spread well up the sides also, the pan I used is 20 x 30cm. I was super light on the spray - only a few light puffs then used my finger tips to spread it around - you don't want it tasting of cooking oil!
- Stir together tap water and jelly crystals in a glass bowl and microwave for 1 minute.
- Remove bowl and stir well.
- If necessary, return to microwave for 20 seconds or so to make sure jelly is completely dissolved and stir again.
- Add marshmallows and return to microwave for 20-40 seconds or until marshmallows have just begun to puff.
- This is the key to a successful marshmallow layer! If you over cook the marshmallows, they just dissolve and your roll-up will not have two distinct layers.
- Whisk quickly until marshmallows are dissolved.
- Pour quickly into prepared pan and chill in fridge for 1 hour or until well set. And this is where the cool bit happens! The marshmallow layer will rise to the top!
- Remove the pan from fridge. At this point, the jelly should be very firm and easy to handle.
- Gently pull one side away from pan and lift entire sheet onto counter. Starting at one end, roll up tightly.
- With seam side down, cut into 1/2 inch slices. I find that it is easiest to cut this with some cotton or thread, just put cotton underneath then cross over to slice. The kids loved doing this bit, cutting food with sewing stuff! Also be prepared for it all to be a bit sticky! Mine was quite sticky today - other days not so much - who knows why but its jelly & marshmallows - destined to be a sticky treat!
- This needs to remain chilled until you serve.
- Enjoy!

My Bunco group would love these. Could you spike it with Marshmallo Vodka instead of water?
justamumnz says
I have not tested with vodka but please let me know if you try it
Kate says
I have made these heaps of times very successfully. The red is great but I have had to throw the green out every time I make it. It looks a terrible snotty grey colour. why can’y I get the vibrant green that shows in the pics?
justamumnz says
How weird! Hmm I wonder if it’s because of the marshmallows? Try making it with just white and see how you get on? Sorry to hear about your snotty grey Rollups! ?
denise says
hi, why does the jelly break up when rolling? As long as its jelly, the brand doesn’t matter right?
justamumnz says
I am not sure sorry, could it be that you are cooking the jelly too long? It may break up if not enough moisture but I have not come up against it doing that yet. 🙂
Kelly says
These look so easy! Great for parties!
justamumnz says
Thank you Kelly, they are so easy and super fun to be able to make in any colour you can find in Jelly! 😀
Amy says
would these work if I cut up larger marshmallows? I cannot source mini marshmallows that are gluten/nut free. Cheers.
justamumnz says
Yes they should work fine, cut small and same cooking method. Let me know how you get on 🙂
Rovena says
Such a neat idea, they look amazing! I’m going to use these for a science lesson about dissolving and solubility. I did a test run yesterday and noticed the jelly split very easily as I rolled it – any tips? I refrigerated the mix for about 4 hours too. Thanks!
justamumnz says
Hmm, not sure sorry! Setting too long or heating too much?
Michelle says
Hi there I made the jelly roll ups today but my jelly was not as bright as yours did I heat the marshmallows a bit long?
Rachel says
These are great double layered and cut into squares..
justamumnz says
Great idea! 🙂
Sharn says
These look amazing! I think it would look awesome in shot glasses or something similar too
justamumnz says
Great idea Sharn! In fact I am totally going to steal it and try a few different things out! Thanks for the idea lol
Sharlene Nash says
You can even make 2 different colours in separate pans but then when set put one on top of the other and roll together for a 2 colour scroll! Great if your having a pink and purple party or something!!
justamumnz says
Sounds great – I haven’t tried that yet but I bet it would look awesome! 🙂
JEANETTE says
Hi!
How long would these rolls last in a cooler, before it`s not eatable?
justamumnz says
I would say 12 hours is their maximum – although not tested for much longer than that! They tend to dry out a little the longer they are left 🙂
JEANETTE says
Thanx 😉
Caity says
I’m planning to make these tomorrow with the kids I babysit but I was just wondering if you can use a knife to cut the roll?
justamumnz says
Hi Caity, you could, but it will not cut through as smoothly or be as easy but yes! If you definitely cannot find any cotton (only need about 15-20cm of it – got some hanging from an old shirt!? lol) then perhaps heat the knife first under warm water if you are finding it difficult to get clean cuts 🙂 Have fun!

Teree says
My 4 kids have serious food allergies (one suffering from anaphylaxis), and between them are allergic to dairy, egg, bananas and nuts. Jelly and marshmallows are two of their few treats that they can have, and together, they’re amazing! I make these weekly now for my littlies, and they all get excited. Thank you so much for sharing.

I can’t wait to try these. I have never eaten these or ever seen them. I think my little boy will be happy to try these out. I was a little confused you seen pour into prepared pan …how do you prepare the pan ? and what kind of pan? Thank you for sharing.

Just a Mum says
Hi Kim, I use my normal slice pan that is approx 20cm x 30cm. And I prepare the pan by very lightly spraying it with cooking spray. It is such a fun recipe, let me know if you try it out 🙂
donna phasey says

Just a Mum says

emma says
hi there i dont have a microwave can i still make it without one my kids would love this
Just a Mum says
Hi Emma, yes I think you easily can. On the stovetop heat the jelly as per recipe until it is quite hot but not boiling and until the crystals have just dissolved, should not take long, then add the marshmallows to the jelly and let them heat until they are just starting to puff up – then remove from heat and quickly whisk together and pour into tin. Let me know how you get on 🙂 Thanks for stopping by 🙂
Susanne Compton says
How good do these look? A fun treat for school shared lunches Thanks 🙂
Just a Mum says
They look amazing – try them in green for St Patrick’s Day – just remember they need to be chilled right up until you eat them 🙂
Mary Murphy says
What a clever idea, my dad is 86 and likes jelly , this will be a nice treat on a Sunday Afternoon
Vicky Devine says
Thanks for the recipe I cant wait to make them
Vicky Devine says
Is the water boiling water or cold water when you add the jelly crystals, (silly question but you normally make jelly with boiling water)???
Just a Mum says
Hi, sorry its not clear – you just add normal cold tap water – as you are heating it in the microwave – I remember checking on that too! Will amend recipe 🙂
