Ingredients
Jell-O Shell
1 box (0.3 oz) sugar-free Jell-O (any flavor; blue raspberry & cherry are popular)
1 cup boiling water (half-water trick for stronger flavor)
Lava Filling
½ cup sugar-free Cool Whip
1–2 tbsp protein powder (clear or vanilla unflavored works best)

Tiny drop of vanilla extract
Liquid stevia (if you want extra sweetness)
Step-by-Step Instructions
- Make the Concentrated Jell-O
In a heat-safe bowl, add the Jell-O powder.
Pour in 1 cup boiling water (do not add cold water).
Stir slowly for 2 full minutes, until every crystal is completely dissolved. - Mold & Set
Pour the liquid Jell-O into mini silicone cube molds.
Refrigerate for 2 hours, or until fully firm. - Prepare the Lava Filling
In a small bowl, mix:
Sugar-free Cool Whip
Protein powder
Stir until completely smooth (no lumps).
The filling should be thick but pipeable.
- Create the Lava Center
Remove Jell-O cubes from molds.
Using a toothpick or skewer, gently create a small hollow in the center of each cube (don’t break through). - Fill the Cubes
Spoon or pipe about ½–1 teaspoon of the creamy filling into each cavity.
Smooth the top lightly with a damp finger or spoon. - Final Chill
Place filled cubes back into the fridge for 1–2 hours, until firm again.
