Prep time: 5 minutes
Chill time: 2–3 hours
Total time: about 2½–3 hours
🛒 Ingredients
1 box sugar-free Jello, any flavor, about 0.3 oz (8.5 g)
1 cup boiling water
1 cup plain Greek yogurt
½ cup cold water
Optional
Fresh berries for topping
A few drops of vanilla extract
Sugar-free whipped topping
Unsweetened shredded coconut
👩🍳 Instructions
1. Dissolve the Jello
Add the sugar-free Jello powder to a large mixing bowl.
Pour in 1 cup boiling water.
Whisk continuously for about 1–2 minutes, until the powder is completely dissolved.
2. Add cold water
Pour in ½ cup cold water and stir well.
Let the mixture cool for about 5–10 minutes. It should be cool or just slightly warm—not hot.
3. Add Greek yogurt
Add 1 cup Greek yogurt.
Whisk until completely smooth and creamy.
For an extra-smooth texture, use a hand mixer for about 30–60 seconds.
4. Chill
Divide the mixture among 4–6 small dessert cups or leave it in one larger container.
Refrigerate for 2–3 hours, or until completely set.
5. Serve
Top with a few fresh berries or a spoonful of sugar-free whipped topping if desired.
Serve cold.
⭐ For an Extra-Fluffy Texture
For the texture shown in the picture, use full-fat or 2% Greek yogurt rather than fat-free yogurt.
You can also beat the mixture for an additional minute after adding the yogurt. This incorporates a little air and creates a lighter, mousse-like consistency.

❓ Q&A
Can I use regular yogurt?
Yes, but Greek yogurt gives the dessert a thicker and creamier texture.
Can I use flavored Greek yogurt?
Yes, but plain Greek yogurt gives you better control over the flavor and sweetness.
Can I use fat-free Greek yogurt?
Yes. It will work, although the finished dessert may be slightly less creamy.
Does the Greek yogurt need to be cold?
Cold or refrigerated yogurt is best, but allow the dissolved Jello mixture to cool first so the yogurt doesn’t become warm or develop a grainy texture.
Why didn’t my Jello set?
Make sure you use the correct amount of water. Too much liquid can prevent the dessert from becoming firm.
Can I make it without the cold water?
Yes, but the texture and setting time can change. Following the recipe’s water amounts gives the most reliable result.
Can I make this higher in protein?
Yes. Use a high-protein Greek yogurt. The exact protein amount will depend on the yogurt brand.
Can I add berries?
Yes. Fresh strawberries, raspberries, blueberries, or blackberries are delicious.
Can I make it ahead?
Absolutely. Cover and refrigerate for up to 3 days.
Can I freeze it?
It’s better not to freeze it. Freezing and thawing can make the yogurt mixture watery and change the texture.
Is sugar-free Jello actually sugar-free?
Many products labeled sugar-free contain no added sugar but may contain artificial or alternative sweeteners. Check the nutrition and ingredient label of the specific product you use.
Can I make individual portions?
Yes. Divide the mixture into small glasses, jars, or dessert cups before chilling. This makes an easy grab-and-go dessert.
