Easy vegan jello made with unsweetened fruit juice and agar agar seaweed gelatin flakes. Perfect for a fun snack or a light dessert!

I remember pulling a big pan of jello out of the fridge as a kid and cutting it into giant, wobbly squares. Cherry was my favorite. After switching to a plant-based lifestyle, I assumed those jello days were over—until I discovered agar agar, a seaweed-based gelling agent that makes perfectly jiggly, vegan jello using just fruit juice and a little heat.
This recipe makes a simple, no-sugar-added vegan jello that relies on the natural sweetness of fruit juice. It’s great for kids, portable as individual snack cups, and easy to customize with whatever 100% juice you have on hand. Below you’ll find the straightforward ingredients, clear instructions, helpful tips, and serving ideas so you can make this light dessert with confidence.

2-Ingredient Vegan Jello Cups (No-Sugar-Added!)
Author: Flora & Vino
Total Time: 25 minutes
Yield: 6–8 jello cups
Diet: Vegan
Description
Light, bouncy vegan jello made from unsweetened fruit juice and agar agar flakes. No added sugars, no gelatin, and a delightful, nostalgic texture. Use 100% fruit juice for sweetness and flavor, and experiment with different juices to make colorful, healthy snack cups.
Ingredients
- 4 cups no-sugar-added fruit juice (100% juice; grape, apple, pineapple, or orange work well)
- 6 tablespoons agar agar flakes
Note: Choose a juice with only fruit listed on the label and no added sugars. Avoid green or vegetable-heavy juices if you want a sweet, dessert-like result.
Instructions
- Add the fruit juice to a large saucepan and sprinkle in the agar agar flakes.
- Heat the mixture over medium heat, whisking frequently so the flakes dissolve evenly.
- When the mixture reaches a low boil, lower the heat and simmer gently for 5 minutes to fully activate the agar.
- Remove from heat and let cool just enough to handle, then pour into glass jars or small cups.
- Cover and refrigerate until firm and chilled. Serve after about 1 hour or whenever the jello is set and cool to the touch.
- Store leftover jello cups in the refrigerator for up to one week.
Tips, Variations, and Serving Ideas
• Dissolving agar: Whisk constantly in the first minutes of heating to help the flakes dissolve. Clumps can reduce gelling effectiveness and cause uneven texture.
• Juice choices: Grape juice gives a classic, rich color and flavor. Apple, pineapple, and orange juices also set beautifully and create different flavor profiles. For a tart variation, mix a little unsweetened cranberry with another juice.
• Texture: Agar sets more firmly than animal gelatin and will hold its shape well at cooler room temperatures. If you prefer a softer set, reduce agar slightly and test with a small batch first.
• Add-ins: For a special touch, stir in whole fruit pieces after the mixture cools slightly (but before it gels). Small berries or diced peaches work well. If adding fruit, cool the warm mixture so delicate fruit doesn’t break down.
• Toppings: Serve plain or top with coconut whipped cream, a dollop of plant-based yogurt, or fresh fruit for contrast. These jello cups also work well layered with chia pudding or a creamy pudding alternative.
• Kid-friendly: Pour into small jars or reusable cups for easy snack portions. Kids can help pour and watch the jello set, which makes it a fun kitchen activity.
Storage and Make-Ahead
Refrigerate finished jello cups in an airtight container or covered jars. They keep well for up to one week. These are great to prepare ahead for parties, lunchboxes, or grab-and-go snacks during the week.
