Ingredients (With Roles Explained)
1 box Berry Blue Jell-O Gelatin Dessert
This is the star ingredient that creates the bold, ocean-like color. Berry Blue is ideal because it produces that iconic deep-sea translucent blue that makes the gummies look like they’re floating.
1 cup boiling water
Boiling water is essential for fully dissolving the gelatin powder. This step ensures your cubes set properly and stay smooth instead of grainy.
Cold Sprite (from a 2-liter green bottle)
Sprite adds a subtle lemon-lime sweetness and gives the Jell-O a lighter flavor. The carbonation creates a fun “fizzy” vibe and can add a slightly airy texture. Using it cold helps preserve bubbles and prevents the gummies from melting.
Trolli Sour Brite Octopus Gummies
These neon gummies are the “shark bait” that makes the recipe unforgettable. Their bright colors pop through the blue gelatin, and the sour flavor creates a fun contrast against the sweetness of the Jell-O.
Clear silicone large square ice cube trays
The clear molds make the cubes look professional and polished. Silicone is also crucial because it makes unmolding effortless without cracking the gelatin.
How to Make Blue Jell-O Shark Bite Cubes (Step-by-Step)
Step 1: Dissolve the Blue Jell-O
In a glass measuring cup, pour in 1 cup boiling water. Add the entire box of Berry Blue Jell-O powder and whisk vigorously for about 1–2 minutes, until completely dissolved.
Pro Tip: Make sure there are no visible granules—this is the key to getting that smooth, glassy finish.
Step 2: Stir in the Cold Sprite
Slowly pour in the cold Sprite, gently stirring as you go. It will fizz up, which is totally normal.
Important: Stir gently to avoid losing too much carbonation.
Step 3: Add the Gummy Octopus “Sea Creatures”
Place one Trolli Sour Brite Octopus into each cavity of your silicone ice cube tray.
Position them tentacles-up if you want the cubes to look extra dramatic.
Step 4: Fill the Mold
Carefully pour the blue Jell-O mixture into each mold cavity until full. Pour slowly to avoid dislodging the gummy or creating too many bubbles.
Step 5: Refrigerate Until Set
Place the tray in the refrigerator and chill for at least 3 hours, or until fully firm.
Once set, you’ll have gorgeous jiggly, translucent blue cubes with bright gummy octopus creatures suspended inside like underwater bait.
Pro Tips for Perfect Shark Bite Cubes
Use Cold Sprite Only
Warm soda will flatten instantly and can cause cloudy gelatin. Cold Sprite helps preserve the clean look and keeps the texture firm.
Don’t Over-Stir
Once Sprite is added, excessive stirring kills carbonation and can create foam that ruins the clarity.
Pour Slowly for Crystal Clear Cubes
A slow pour prevents bubbles and keeps the gelatin looking like clear ocean water.
Chill Overnight for Best Results
While 3 hours works, letting them chill overnight makes the cubes firmer and easier to remove cleanly.
Unmold Like a Pro
Gently push from the bottom of the silicone tray rather than pulling from the top. This keeps edges sharp and prevents tearing.
Serving Suggestions (Make Them Party-Perfect!)
These cubes are amazing on their own, but you can take them to the next level with themed presentation:
Ocean Party Platter
Serve on a tray lined with crushed ice and scatter extra gummy sea creatures around the cubes for a full underwater vibe.
“Shark Tank” Dessert Bowl
Pile cubes into a clear glass bowl and add Swedish Fish, gummy sharks, or sour worms for a dramatic “sea creature tank” look.
Kids Party Dessert Cups
Drop 2–3 cubes into clear plastic cups and top with whipped cream or extra candy for a grab-and-go treat.
Halloween Twist
Add a few drops of edible black gel coloring swirled into the mix for a spooky deep-sea effect.
