Jello Roll-Ups: A Nostalgic Treat with a Modern Twist
There’s something wonderfully nostalgic about certain foods, especially those that remind us of simpler times and family gatherings. One such treat is the beloved Jello roll-up, or Jello pinwheels as some call them. These colorful, sweet, and playful snacks were once a staple at many of my family gatherings, and like many childhood favorites, they’ve somehow disappeared from the scene as we’ve all grown older. But recently, I decided to bring them back—both for old times’ sake and because I genuinely missed them. Not only are they easy to make, but they’re also highly customizable, so you can tailor them for any occasion or just indulge in your favorite flavors.
Let’s dive into how you can recreate these fun treats and why they’ll soon become a go-to recipe in your home.
Ingredients
To get started, you’ll need the following ingredients:

- 1/2 cup water
- 1 (3 oz) box of Jello
- 1 1/2 to 2 cups marshmallows (fresh marshmallows work best for this recipe)
While the ingredients are simple, the magic lies in how you layer them together. The marshmallows add a delightful texture and flavor that perfectly complements the Jello.
Supplies
Before you begin, gather these supplies:
- Microwave-safe bowl (make sure it’s large enough to accommodate the marshmallows as they expand when heated)
- Mixing spoon
- Measuring cups
- 8×8 inch glass dish (this dish should be able to handle both hot and cold temperatures; a dish with a lid is ideal to keep the roll-ups fresh)
- Non-stick spray (to prevent sticking)

Step 1: Prepare the Jello
The first step is a simple one: dissolve the Jello in 1/2 cup of boiling water. Stir until the Jello is completely dissolved. This process sets the base for your roll-ups, giving them their vibrant color and flavor. You can choose any flavor you like—red and green are perfect for holidays, while orange, yellow, and blue are ideal for fun, everyday occasions. Get creative with the colors!
Step 2: Melt the Marshmallows and Cool
Now, it’s time to bring in the marshmallows. Add them to the Jello mixture and microwave for about one minute. It’s crucial not to over-melt the marshmallows, as you want to maintain some texture and layering in your roll-ups. If you overdo it, the marshmallows will dissolve too much into the Jello, and you won’t get the distinct layering that makes this treat so special. Stir the mixture and check if the marshmallows have melted sufficiently—some chunks are okay!
A tip: If you’re using older marshmallows that have become a little harder, they might not melt as smoothly. In that case, it’s better to under-melt them rather than risk losing the texture altogether.
Once the marshmallows are melted, pour the mixture into your greased 8×8 inch dish. Be sure to spread it out evenly, then refrigerate it for 1-2 hours until it’s fully set. It’s important to cover the dish to prevent it from becoming tacky, which could make it difficult to roll later on.
Step 3: Cut and Roll
After the mixture has set and is firm to the touch, it’s time to cut and roll. There are a couple of methods you can use here. Some people like to roll up the entire block of Jello like a cinnamon roll and then slice it into smaller pieces. This method is quick and works fine, but I prefer using a pizza cutter to cut the mixture into strips, which I then roll up. This approach allows for a more controlled, uniform size and makes the final product look even more appealing.

You can experiment with both techniques—both are effective, and the result will be just as delicious!
Step 4: Enjoy!
Once your Jello roll-ups are cut and rolled, you’re ready to enjoy! Keep them refrigerated to maintain their texture and flavor. They make an excellent snack or party treat, and their bright colors make them especially fun for kids or themed events like birthdays and holidays.
Tip for Success: If you’re aiming for a perfect layered look, it’s essential to use fresh marshmallows, as they melt beautifully and help maintain the separation between layers. Old marshmallows, on the other hand, can be a bit tricky. In my experience, older marshmallows tend to either under-melt, resulting in a more subtle layering, or over-melt, causing the layers to blend together.

Final Thoughts
Jello roll-ups are a fun, easy-to-make treat that’s sure to bring a little bit of joy to your day. Whether you’re making them for a family gathering, a party, or just for a sweet, nostalgic snack, they’re sure to be a hit. Plus, their versatility allows you to customize them for any occasion by simply switching up the flavors or colors. Give them a try and enjoy a blast from the past that’s as delicious as it is colorful!
