Sugar-Free Strawberry Jell-O Mousse Cups
From the photo, this looks like a light, fluffy strawberry mousse made with sugar-free strawberry Jell-O, portioned into small cups. The exact original recipe can’t be determined from the image alone, but the version below is designed to produce the thick, pale-pink, spoonable texture shown.
It is an easy 3–4 ingredient dessert and works especially well for meal prep, parties, or a low-sugar treat.
Recipe Overview
Yield: 6–8 small cups
Prep time: 10–15 minutes
Chilling: 2–4 hours
Difficulty: Very easy
Cooking: No baking required
Ingredients
Main recipe
1 box (0.3 oz / 8.5 g) sugar-free strawberry Jell-O
1 cup boiling water
1 cup cold water
8 oz (225 g) light or regular whipped topping, such as Cool Whip, thawed
Optional for stronger strawberry flavor
½ cup fresh strawberries, finely chopped or puréed
½ tsp vanilla extract
1–2 drops strawberry extract, optional
For decorating
Fresh strawberries
A small spoonful of whipped topping
Sugar-free strawberry syrup, optional
FULL STEP-BY-STEP RECIPE
1. Dissolve the Jell-O
Pour 1 cup boiling water into a large mixing bowl.
Add the entire packet of sugar-free strawberry gelatin.
Whisk continuously for about 1–2 minutes.
The gelatin should be completely dissolved.
Important
Don’t add the cold water immediately if there are still undissolved crystals.
Run your fingers through a cooled spoonful or look closely—there shouldn’t be visible grains at the bottom.
2. Add the cold water
Add 1 cup cold water.
Whisk well.
At this point you have prepared strawberry gelatin.
3. Cool the gelatin
Place the bowl in the refrigerator for approximately 30–45 minutes.
You don’t want it completely set.
You’re looking for a consistency that’s:
cool + slightly thickened + still pourable.
This step matters
If you mix whipped topping into hot gelatin, the whipped topping can melt and the finished dessert may become thin.
4. Whip the gelatin
Once cooled and beginning to thicken, use an electric mixer.
Beat for approximately 2–3 minutes.
The mixture should become lighter and somewhat foamy.
5. Fold in the whipped topping
Add the thawed whipped topping gradually.
Start with about ⅓ of the container.
Fold gently.
Add another third and fold.
Then add the remaining whipped topping.
Mix until the mousse is uniformly pale pink.
Don’t overmix
Gentle folding gives you the fluffy texture visible in the photograph.
6. Add strawberries — optional
For a more natural strawberry flavor, finely chop ½ cup fresh strawberries.
Pat them dry with paper towels.
Fold them gently into the mousse.
Alternatively, purée the strawberries and swirl them through the mixture.
For the exact appearance in the photo
I’d actually leave the fruit pieces out.
The photograph shows a very smooth, pale-pink mousse with tiny strawberry-colored specks rather than large fruit chunks.
7. Portion into cups
Spoon or pipe the mousse into:
6 larger dessert cups, or
8 small 5–6 oz cups
Fill each approximately ¾–⅞ full.
For the pointed swirl shown in the picture, transfer some mousse to a piping bag and pipe a small spiral or peak on top.
8. Refrigerate
Cover the cups.
Refrigerate for at least:
2 hours
For the best texture:
4 hours or overnight.
The mousse will become noticeably thicker as it chills.
9. Decorate
Just before serving, add:
a small strawberry
fresh strawberry slices
a tiny dollop of whipped topping
For a sugar-free dessert, use a sugar-free strawberry sauce if desired.
Even Creamier Version
If you want something closer to a thick cheesecake-like mousse, use:
1 box sugar-free strawberry Jell-O
¾ cup boiling water
½ cup cold water
8 oz whipped topping
4 oz softened cream cheese
Method
Beat the cream cheese until smooth.
Prepare the gelatin with the reduced amount of water.
Cool it until slightly thickened.
Beat the gelatin, then gradually beat in the cream cheese.
Fold in the whipped topping.
Chill for 3–4 hours.
This produces a richer, denser dessert.
Greek Yogurt Version
For a higher-protein option, replace approximately half of the whipped topping with Greek yogurt.
Ingredients
1 box sugar-free strawberry Jell-O
1 cup boiling water
½ cup cold water
1 cup plain or vanilla Greek yogurt
1 cup whipped topping
Cool the gelatin first, then blend in the Greek yogurt and fold in the whipped topping.
This version is tangier and more substantial than the pictured mousse.

RECIPE Q&A
Why isn’t my mousse fluffy?
The gelatin was probably too warm when the whipped topping was added.
Let the gelatin cool and begin to thicken before incorporating the topping.
Why is my mousse runny?
Possible causes:
gelatin wasn’t completely dissolved
too much liquid was added
gelatin was mixed while still very hot
the dessert hasn’t chilled long enough
fresh strawberries released excess water
Fix: refrigerate for several more hours.
Can I use regular Jell-O instead of sugar-free?
Yes.
Use one standard 3-oz / 85-g box of strawberry gelatin.
You may need to adjust the amount of water according to the package directions, especially if you’re making a mousse rather than regular Jell-O.
Can I use another Jell-O flavor?
Absolutely.
Good choices include:
Strawberry
Cherry
Orange
Lemon
Pineapple
🫐 Berry/blueberry
Strawberry gives the closest result to the photograph.
Can I use fresh strawberries?
Yes.
But don’t add a large amount of watery fruit.
For every 6–8 cups, ½ cup finely chopped, well-dried strawberries is plenty.
Can I make it without Cool Whip?
Yes.
You can substitute 1½ cups heavy whipping cream, whipped to stiff peaks.
For a less sweet mousse, use unsweetened whipped cream and adjust sweetness to taste.
Can I use homemade whipped cream?
Yes.
Whip 1½ cups cold heavy cream with approximately 2–3 tbsp powdered sweetener or sugar until stiff peaks form.
Then fold it into the cooled gelatin.
Homemade whipped cream tends to be softer than stabilized commercial whipped topping, so keep the mousse refrigerated.
Can I make it ahead?
Yes.
This is an excellent make-ahead dessert.
Prepare it the day before, cover the cups, and refrigerate.
Add fresh fruit immediately before serving.
How long will it keep?
Keep refrigerated and use within approximately 3 days for the best texture.
Keep the cups covered so they don’t absorb refrigerator odors.
Can I freeze it?
I don’t recommend freezing the finished mousse.
Freezing can cause the whipped topping to separate and produce a watery texture after thawing.
Can I make it in one large bowl?
Yes.
Pour the mixture into an approximately 8×8-inch dish or similar serving dish.
Chill until firm and scoop it out.
Individual cups are better if you’re trying to reproduce the presentation in the photograph.
Why did my mousse separate?
This usually happens when the gelatin is too warm or the whipped topping is incorporated too aggressively.
Cool the gelatin until slightly thickened and fold rather than vigorously stir.
Can children help make it?
Yes. This is a good no-bake recipe for children to help with, although an adult should handle the boiling water.
BEST VERSION FOR THE PHOTO
If your goal is to reproduce the exact style shown, I’d use:
1 box sugar-free strawberry Jell-O + 1 cup boiling water + 1 cup cold water + 8 oz light whipped topping.
Then:
Completely dissolve Jell-O.
Add cold water.
Refrigerate until slightly thickened.
Beat until airy.
Fold in whipped topping.
Pipe into clear cups.
Refrigerate 4 hours or overnight.
Pipe a small peak on top.
Add a tiny fresh strawberry for decoration.
