1. In a bowl, dissolve lime jello in 1 cup of boiling water. Stir until fully dissolved. Add 1 cup of cold water. Optionally, stir in crushed pineapple or marshmallows. Pour into a 9×13 glass dish and chill for 1 hour until firm.

2. In a small bowl, sprinkle unflavored gelatin over 1/4 cup cold water and let it bloom for 5 minutes.

3. In another bowl, beat cream cheese until smooth. Warm the condensed milk slightly and stir it in.

4. Heat the bloomed gelatin until dissolved (microwave 10 seconds if needed), then stir it into the cream cheese mixture. Pour this layer over the green jello and chill for 1–2 hours.

5. Dissolve red jello in 1 cup boiling water, add 1 cup cold water, and let it cool to room temp. Gently pour it over the cream layer and refrigerate for another 1–2 hours.

6. Before serving, top with whipped cream and garnish with lime zest or sprinkles. Cut and serve chilled.
