Bring 1 cup of water to a boil. Remove from heat and whisk in the lemon jello until fully dissolved (about 1-2 minutes).
Non-Alcoholic Version: Stir in 1 cup cold water and mix well.
Alcoholic Version: Stir in ½ cup cold water and ½ cup vodka or whiskey, mixing thoroughly.
Carefully pour the jello mixture into mini shot cups, filling nearly to the top. Use a funnel or a measuring cup with a spout for easy pouring.
Place the cups on a baking sheet for stability and refrigerate for at least 4 hours until fully set.
Once set, decorate before serving. Add whipped topping, gold sprinkles, and a 1 to 1½-inch piece of rainbow belt candy for a festive touch.
