Make the Best Under the Sea Jello Cups
Making these jello cups is easy and fun! Start by boiling 1 ½ cups of water. While it heats, sprinkle about ½ teaspoon of Nerds candy into the bottom of each jello cup to create a colorful, rocky ocean floor.
In a mixing bowl, pour in the Jell-O mix, then carefully add the boiling water. Stir until the powder fully dissolves, then mix in 1 ½ cups of cold water.
Pour the jello mixture into each cup, filling them about ¾ of the way. Refrigerate for at least 2 hours, allowing the jello to fully set.


Once firm, top each cup with an edible mermaid tail and a mini fork for that fun, whimsical touch. Serve and enjoy your magical under-the-sea treat!
