Mix the base – In a large mixing bowl, combine the cottage cheese, drained crushed pineapple, and dry Jello powder. Stir until well combined.
Fold in Cool Whip – Gently fold in the Cool Whip until the mixture becomes light and fluffy. Avoid overmixing to keep the texture airy.
Chill – Transfer the mixture to a serving dish, cover it, and refrigerate for at least 1 hour (or overnight for the best texture).
Serve & enjoy – Scoop onto plates, serve in dessert cups, or eat straight from the bowl!
