Protein jello mousse is a chilled dessert made by combining dissolved flavored gelatin with Greek yogurt, then refrigerating it until set. The yogurt gives it a creamy texture and contributes protein. Cool the gelatin until it is no longer hot before whisking in the yogurt, but combine them before the gelatin starts to set.
This RecipeCrave adaptation is inspired by I Hacked Diabetes’s Greek Yogurt Protein Jello Mousse. The recipe below is rewritten for this site and has not been kitchen-tested. Mixing and chilling times are estimates.
Protein jello mousse at a glance
- Texture: creamy, spoonable, softly set gelatin.
- Method: dissolve, cool, whisk and refrigerate.
- Yield: four small dessert portions.
- Flavor: strawberry, with tang from plain yogurt.
- Planning: allow about three hours of refrigeration, plus preparation and cooling.
Choosing ingredients before you start
The gelatin mix is the most important product to check. Different brands use different sweeteners, packet sizes and gelling ingredients. A tablespoon measure for one product may not be interchangeable with an entire packet of another. Choose a gelatin-based strawberry dessert mix and check the manufacturer’s preparation directions before measuring.
Use plain Greek yogurt so that you can control the flavor. Sweetened strawberry yogurt adds its own sugar, flavoring and color. A thicker or higher-fat yogurt can produce a different result; this adaptation does not establish that every substitution gives the same texture.
You do not need protein powder for the base version. If you add it, treat it as a variation that needs a small trial. Powder blends differ in sweetness and how readily they disperse, and a scoop is not a consistent weight across brands.
Protein Jello Mousse with Greek Yogurt
Prep: about 10 minutes, plus cooling · Chill: about 3 hours · Makes 4 small portions
Equipment
Heatproof bowl, whisk, measuring cups and four serving cups.
Ingredients
Optional topping: sliced strawberries. Gelatin mix brands vary; check the product before substituting. Contains milk.
Instructions
- Dissolve the measured gelatin mix completely in the boiling water in a heatproof bowl.
- Let the liquid cool until no longer hot, keeping it fluid.
- Whisk the yogurt until smooth, then gradually whisk in the cooled gelatin liquid.
- Divide among four small cups. Refrigerate until set, allowing about 3 hours or longer as needed.
- Serve chilled; add optional strawberry slices just before serving.
Not kitchen-tested. Times are estimates. Ingredient scaling does not adjust the directions or establish a new setting time.
How to keep the mixture smooth
Keep the dissolving and mixing stages separate. First inspect the liquid gelatin for undissolved particles. Next smooth the yogurt in its own bowl. Combining a smooth liquid with smooth yogurt makes it easier to notice any lumps before portioning.
Set out your serving cups before mixing. Once the yogurt and gelatin are combined, divide the mixture promptly rather than leaving it in the bowl while you look for containers. If the mixture has already become lumpy and partially set, whisking alone may not restore a uniform texture.
Why this is different from gelatin cubes
This dessert is intended for a spoon. Do not use its ingredient proportions to make firm, portable cubes. If you want a cuttable snack instead, see our strawberry protein gelatin cubes. The two recipes have different textures and serving methods.
How much protein is in each serving?
Use your own package labels to calculate it. Add the protein in the amount of yogurt and gelatin mix you use, include any optional protein powder, then divide the batch total by four. For a different batch size, divide by the number of portions actually served.
RecipeCrave has not calculated nutrition for this adaptation. Using a sugar-free gelatin mix does not make the whole dessert sugar-free: yogurt may contain naturally occurring sugars. Check each ingredient and topping rather than applying a dietary label to the entire recipe from the mix alone.
Frequently asked questions
Can I make protein jello mousse without protein powder?
Yes. The base recipe uses Greek yogurt as its main protein-containing ingredient. Powder is optional and changes the formula.
Can I use regular yogurt?
Regular yogurt can be thinner than Greek yogurt. Replacing it may change how the dessert sets, so test a small batch before making it for guests.
Does gelatin make this vegetarian?
No. Conventional gelatin is animal-derived. A dessert mix made with a different gelling ingredient would need its own method and testing.
Should I add cold water as directed on the gelatin box?
Follow one complete formula. This adaptation lists its own water and yogurt quantities; adding the box’s additional water would change that ratio. If your mix has substantially different preparation directions, choose a recipe developed for that product.
Can I double the batch?
The calculator scales ingredient quantities. Use additional individual cups and check each portion for setting; multiplying quantities does not prove that the same chilling time will work.
Serving and recipe notes
Keep the dessert refrigerated and add fresh toppings shortly before serving. Follow the storage directions on your yogurt and gelatin products. Label the container with the preparation date, and prepare modest batches while evaluating this untested adaptation.
