These tropical Jello shots bring island vibes to any party. Sweet, creamy, and boozy, they taste like a mini Piña Colada in every bite-sized cup.
Store in the fridge for up to 3 days, covered with plastic wrap to avoid fridge odors. Make ahead the night before your event. Label clearly if kids are around. To make non-alcoholic, replace the rum with coconut milk or pineapple juice. Do not use fresh pineapple juice—it prevents setting.
