Full Recipe (Detailed)
Ingredients
1 container (8 oz) sugar-free Cool Whip (or equivalent light whipped topping)
1 small package (3 oz) sugar-free strawberry Jell-O (gelatin mix)
1/3 cup fresh strawberries, finely chopped (plus extra for garnish, optional)
1/4 cup cold water (optional, depending on how firmly you want the mousse)
Instructions
- Prepare the gelatin
In a small bowl, dissolve the entire strawberry Jell-O packet in about 1/2 cup of boiling water (follow the directions on the package for dissolving).
Once fully dissolved, add about 1/4 to 1/2 cup of cold water to the gelatin to help cool it down. (Adjust depending on how loose or firm you want the mousse.)
- Cool the gelatin
Allow the gelatin mixture to cool for 5–10 minutes at room temperature. It should be still pourable but not hot, so it will not deflate the whipped topping when mixed.
- Fold in the whipped topping
In a medium mixing bowl, add the sugar-free Cool Whip.
Slowly and gently stir in the cooled gelatin mixture, folding carefully to maintain the light, airy texture. Use a spatula to scrape the bottom and sides, blending until smooth and evenly combined.
- Add strawberries
Gently fold in the finely chopped strawberries. Make sure they are evenly distributed, but avoid overmixing so as not to deflate the mousse.
- Chill and set
Transfer the mousse into individual serving dishes, or pour into a single bowl.
Cover and refrigerate for at least 2 hours, or until the mousse is firm and set to your liking.
Professional Serving Suggestions
Serving Presentation: Use clear glass cups or small stemmed dessert glasses so the soft pink color of the mousse shows through beautifully.
Garnish: Top with a few small strawberry slices, a sprig of fresh mint, or a dusting of sugar-free freeze-dried strawberry powder for a premium look.
Texture Variation: For a bit of crunch, add a small sprinkle of crushed nuts (e.g., almonds or pistachios) or sugar-free granola just before serving.
Layered Dessert Option: Create a parfait by layering the mousse with sugar-free Greek yogurt or a thin layer of sugar-free strawberry compote.
Chilled Service: Keep the mousse chilled until just before serving to retain its structure and maximize its refreshing quality.
