Ingredients
For the Base Cream:
1 box (0.6 oz / 17g) Sugar-Free Blueberry Lemon Jell-O Gelatin mix (or Sugar-Free Lemon Gelatin)
1/2 cup Boiling water
1/2 cup Cold water or ice cubes
1 1/2 cups Low-fat cottage cheese (or plain non-fat Greek yogurt)
1 scoop (30g) Vanilla protein powder
1 cup Sugar-free whipped topping (such as Cool Whip Free), thawed
1/2 tsp Vanilla extract
For the Blueberry Swirl:
1/2 cup Fresh or frozen blueberries (thawed)
1 tbsp Lemon juice
Step-by-Step Instructions
Step 1: Dissolve the Gelatin
1. In a medium bowl, pour 1/2 cup of boiling water over the sugar-free gelatin powder.
2. Whisk continuously for 1 to 2 minutes until completely dissolved.
3. Stir in 1/2 cup of cold water (or ice cubes) to cool down the liquid and set aside for 3 minutes.
Step 2: Blend the Cream Base
1. In a high-speed blender or food processor, combine the cottage cheese, vanilla protein powder, vanilla extract, and cooled gelatin mixture.
2. Blend on high for 1 minute until completely smooth and silky.
3. Transfer the mixture to a bowl and gently fold in the thawed whipped topping until light and fluffy.
Step 3: Prepare the Berry Blend
1. Measure out half of the lemon cream base into a separate bowl.
2. Blend the blueberries and 1 tablespoon of lemon juice in a blender until smooth, then fold this berry puree into one of the bowls to create the deep purple blueberry cream layer.
Step 4: Layer & Chill
1. Alternately spoon or pipe the yellow lemon fluff and purple blueberry fluff into individual meal-prep cups to create a beautiful swirled effect.
2. Cover with lids and refrigerate for at least 2 hours (or overnight) to let the gelatin set into a light mousse.
Chef’s Tips
Smooth Texture: Ensure the cottage cheese is blended thoroughly before splitting into layers so both colors have an identical, silky consistency.
Wild Blueberry Boost: Use wild frozen blueberries for an even deeper purple color and intense berry flavor.
