How to Make Colorful Rainbow Jello for Parties
Mix First Layer: Dissolve one packet of flavored gelatin in 1 cup of boiling water for 2–3 minutes until it is fully dissolved and vibrant. Be patient as this layer sets the tone for your beautiful dessert!
Add Cold Water: Stir in ½ cup of cold water to the dissolved gelatin; it should feel warm but not hot to the touch. This is crucial to ensure a smooth mixture.
Layering Time: Pour the first layer into an 8″x8″ glass dish and refrigerate for about 30 minutes until completely set. You want it firm enough to support the next layer!
Create Creamy Layers: In a separate bowl, mix another gelatin packet with 1 cup of boiling water, add ½ cup of cold water, and stir in ½ cup of sweetened condensed milk until smooth and creamy.
Add Second Layer: Once the first layer is firm, gently pour the creamy mixture over it. Return to the refrigerator and allow it to set for about 30 minutes.
Repeat Process: Continue alternating between flavored gelatin layers and creamy layers until all ingredients are used. It’s essential each layer is set completely before adding the next (approximately 30 minutes each) for those stunning distinct layers.
Serve: Once the final layer is fully set, slice into squares and enjoy the delightful, colorful layers of your Rainbow Jello!
Optional: Top with fresh fruit or whipped cream for an extra tasty treat.

Make Ahead Options
These Rainbow Jello layers are fantastic for meal prep enthusiasts! You can prepare the individual flavored gelatin layers up to 24 hours in advance, ensuring the layers will set perfectly. Simply mix and pour each gelatin layer into your dish, refrigerating them until firm (about 30 minutes each). To maintain the quality, cover the dish tightly with plastic wrap to prevent any absorption of odors from your refrigerator. When ready to serve, you can mix the sweetened condensed milk layer and pour it over the last set gelatin, letting it refrigerate just until fully set (another 30 minutes). This way, you’ll have a stunning dessert ready to impress your guests with minimal day-of effort!
