Ingredients
- 1 package of blue Jell-O: This will create the beautiful water layer.
- 1 package of green Jell-O: Perfect for representing seaweed or underwater plants.

- 1 cup of edible glitter (optional): For that extra sparkle and magic.
- 1 can of whipped cream: To create delightful “waves” on top.
- 1 clear cup or glass for each terrarium: The perfect vessel to showcase your creation.
How to Make Edible Aquarium Terrariums
- Prepare the Jell-O: In separate bowls, prepare the blue and green Jell-O according to the package instructions. Allow both to set in the refrigerator until firm, about 4 hours or overnight.
- Layer the Jell-O: Once the Jell-O has set, cut the blue Jell-O into cubes. In each clear cup or glass, add a layer of blue Jell-O cubes to represent the water.
- Add the “sand”: Sprinkle a layer of crushed graham crackers on top of the blue Jell-O to create the “sand” at the bottom of the aquarium.
- Add the sea creatures: Place the gummy fish or sea creatures on top of the crushed graham crackers.
- Layer the green Jell-O: Cut the green Jell-O into cubes or use a spoon to scoop it out and add it as a layer on top of the gummy creatures, representing seaweed or underwater plants.
- Top with whipped cream: Use whipped cream to create “waves” on top of the terrarium. You can pipe it on for a decorative look.
- Add edible glitter: If using, sprinkle edible glitter on top for a magical, sparkling effect.
- Serve: Your Edible Aquarium Terrariums are now ready to enjoy! Serve them chilled for the best experience.
Substitutions & Additions
If you’re feeling creative, why not substitute the gummy sea creatures with chocolate fish or even fruit snacks? You could also use different flavored Jell-O to mix things up. For a healthier option, you could add fresh fruit like blueberries or kiwi on top for a fruity twist!
Tips for Success
- Make sure the Jell-O is fully set before layering to prevent mixing.
- Feel free to prepare the layers ahead of time; just assemble them before serving.
- If you’re using whipped cream, consider chilling your cups beforehand for a refreshing treat.
How to Store Edible Aquarium Terrariums
These delightful creations are best enjoyed fresh, but if you have leftovers, you can store them in the refrigerator for up to 2 days. Just be sure to cover them to keep them fresh and prevent any unwanted odors.
