Total Time: Approximately 4 hours (plus layer setting time)

Servings: 117 cubes (approx. 1-inch squares)

Author: Trish – Mom On Timeout

Ingredients

• 4 packages (3 ounces each) assorted flavored gelatin (e.g., cherry, orange, lime, blue raspberry)
• 1.5 oz unflavored gelatin, divided (about 4.5 packets, 0.5 oz each)
• 5-3/4 cups boiling water, divided
• 14 oz sweetened condensed milk (one standard can)
• 1/4 cup cold water

Instructions

1. First Flavored Layer: In a small bowl, combine one package of flavored gelatin with one envelope (approx. 0.25-0.375 oz) of unflavored gelatin. Stir in 1 cup of boiling water until all gelatin is completely dissolved. Allow the mixture to cool slightly for 3-5 minutes – this is crucial to prevent melting subsequent layers.
2. Prepare Pan: Lightly coat a 13-inch x 9-inch baking dish with cooking spray for easy removal.
3. Pour First Layer: Carefully pour the slightly cooled flavored gelatin mixture into the prepared dish.
4. Initial Chill: Refrigerate the first layer until it is set but still slightly soft (not firm), typically about 20 minutes. This ensures the next layer adheres without mixing.
5. Prepare Creamy Layer Base: In a separate small bowl, combine the entire can of sweetened condensed milk with 1 cup of boiling water, stirring until well combined.
6. Activate Unflavored Gelatin: In another small bowl, sprinkle two envelopes (approx. 0.75 oz) of unflavored gelatin over 1/4 cup of cold water. Let it stand for 1 minute to bloom. Then, stir in 3/4 cup of boiling water until the gelatin is fully dissolved.
7. Combine Creamy Layers: Add the dissolved unflavored gelatin mixture to the sweetened condensed milk mixture, stirring well to combine. This forms your creamy, opaque white layer.
8. Pour Creamy Layer: Spoon 1 cup of the creamy gelatin mixture very gently over the first flavored gelatin layer. Distribute it evenly without disturbing the set layer below.
9. Chill Creamy Layer: Refrigerate until this creamy layer is set but not firm, approximately 25 minutes.
10. Repeat for Additional Layers: Repeat steps 1 through 9, alternating between flavored gelatin layers and creamy gelatin layers, using the remaining flavored gelatin packages and portions of the creamy mixture. For each new flavored layer, remember to combine one flavored gelatin packet with one envelope of unflavored gelatin and 1 cup of boiling water, letting it cool slightly before pouring.
11. Important Tip for Pure Layers: Always ensure the dissolved gelatin (both flavored and creamy) has cooled slightly before spooning it over the previous layer. This temperature control is key to maintaining distinct, “pure” layers without any bleeding or mixing.
12. Final Chill: After the final flavored gelatin layer has been carefully poured and allowed to set, refrigerate the entire dish for at least 2 hours to ensure all layers are completely firm.
13. Cut and Serve: Once fully chilled and firm, cut the rainbow jello into 1-inch squares or desired shapes. Serve immediately and enjoy your vibrant creation!

Notes

This delightful recipe is adapted from Taste of Home. For best results, ensure your layers are adequately chilled before adding the next one. A slight jiggle is acceptable, but it should not be liquid.

Tips for Rainbow Jello Success

• Temperature Control is Key: Ensure each gelatin layer, especially the colored ones, has cooled slightly (3-5 minutes) before pouring. Pouring hot liquid onto a set layer will melt it, causing colors to bleed.
• Gentle Pouring: To prevent damage to the previous layer, gently spoon the next layer over the top, or pour it over the back of a spoon held just above the surface.
• Achieving Firmness: The “set but not firm” stage means the gelatin is solid enough to support the next layer without mixing, but still has a slight give. If it’s too firm, the layers might separate when cut.
• Sharp Knife for Clean Cuts: Use a sharp, thin knife (dipped in warm water and wiped clean between cuts) to achieve clean, crisp edges on your cubes.
• Storage: Store leftover Jello cubes in an airtight container in the refrigerator for up to 5-7 days.

Creative Variations for Your Jello Masterpiece

• Holiday Themes: Use red and green for Christmas, red, white, and blue for patriotic holidays, or black and orange for Halloween.
• Flavor Combinations: Don’t limit yourself to single flavors. Experiment with complementary flavors like strawberry-banana or lime-lemon.
• Shape It Up: Instead of cubes, use cookie cutters to create fun shapes like stars, hearts, or shamrocks (especially festive for St. Patrick’s Day!). Ensure the Jello is very firm before attempting to cut shapes.
• Fruity Fun: Add small pieces of canned fruit (like mandarin oranges or pineapple tidbits, drained well) to the flavored layers for extra texture. Avoid fresh kiwi, pineapple, or papaya, as their enzymes can prevent gelatin from setting.
• Creamy Alternatives: For a dairy-free creamy layer, you could try using full-fat coconut milk (canned) mixed with a sweetener and unflavored gelatin, though the texture and flavor will be different.
• Adult Version: For a grown-up party, replace a portion of the boiling water in the flavored layers with a clear spirit like vodka or rum (adjusting liquid amounts carefully, usually replacing cold water).
