Sweetened condensed milk.  It’s kind of magical isn’t it?  So sweet and ooey gooey and it just makes everything taste sooo good!  I totally stocked up for the holidays.  I guess I thought I would be making about 47 pounds of fudge or something.  I like to be prepared.

I remember my Dad telling me how my Aunt would eat the sweetened condensed milk by the spoonful out of the can.  Smart lady.  There are so many delicious recipes to make with sweetened condensed milk {most notably Magic Bars} but this particular recipe just happens to work for St. Patrick’s Day!  It’s so fun to make and easy too!  The boys love picking out their favorite flavors of JELL-O and then I put it all together.  I say JELL-O “flavors” but really they go by color.  You know…”the red JELL-O” or “the green JELL-O”.  Whatever works :)


Not only is this dessert beautiful and super-impressive {it looks like it’s really hard to make} but it’s easy on the wallet as well.  You only need some JELL-O, a can of sweetened condensed milk, and some unflavored gelatin.  Easy peasy!  You can choose whatever colors you like which makes this a very versatile dessert.  Layer in the colors of your next party and you’re going to have a yummy treat that’s sure to be a hit!


There’s just something about rainbows that bring a smile to my face every time.  My boys are also thrilled when I “make rainbows” in the kitchen – they are also HUGE JELL-O fans so this treat is a win-win for everyone.  You can really cut down the calories and sugar in this dessert by using sugar-free JELL-O and low-fat or fat-free sweetened condensed milk.   Oh and did I mention this recipe makes TONS of cubes??  Like literally, tons.  Depending on how precise I am with my cutting, I usually end up with between 60-80 cubes so there’s plenty for a crowd OR class!

Rainbow JELL-O Cubes
  • 4 packages (3 ounces each) assorted flavored gelatin
  • 6 envelopes unflavored gelatin, divided
  • 5-3/4 cups boiling water, divided
  • 1 can (14 ounces) sweetened condensed milk
  • ¼ cup cold water
  1. In a small bowl, combine one package flavored gelatin and one envelope unflavored gelatin. Stir in 1 cup boiling water until dissolved. Let mixture cool slightly for 3-5 minutes.
  2. Pour mixture into a 13-in. x 9-in. dish coated with cooking spray.
  3. Refrigerate until set but not firm, about 20 minutes.
  4. In small bowl, combine the condensed milk and 1 cup boiling water.
  5. In another bowl, sprinkle two envelopes unflavored gelatin over cold water; let stand for 1 minute. Stir in ¾ cup boiling water. Add to sweetened condensed milk mixture.
  6. Spoon 1 cup of the creamy gelatin mixture over the first flavored gelatin layer. Refrigerate until set but not firm, about 25 minutes.
  7. Repeat from beginning of recipe twice alternating flavored gelatin with creamy gelatin layers.
  8. Make sure to let the dissolved gelatin sit for a few minutes before spooning over previous layer. This will keep the layers "pure".
  9. Chill each layer until set but not firm before spooning next layer on top.
  10. Make final flavored gelatin and spoon over top.
  11. Refrigerate for 2 hours after finishing last layer before cutting into 1-in. squares.
  12. Serve and enjoy!

  19. Visiting from Monday FunDay’s link up and having had done a Rainbow birthday party for my daughter last summer and having gone through making rainbow striped cookies, I just wanted to tell you how much I REALLY appreciate your effort in making these. They look great and bring back fond memories of layering colours! Great job!

    Popping over from the Monday Funday party to say hello! Just love how these jello cubes look! So eye-catching colorful and just beautiful! These would be so fun to serve at a summer party. Thanks for sharing and am pinning! Have a great week!

  21. Those look so bright and cheery! I was wondering what the white layers were. The condensed milk that I am used to is more of an ivory color. I hope the cubes look as pretty when I make them!

  22. Stopping over from Savvy Southern Style. I had to come by and tell you how much I love these. They’re so cute! They totally do look complicated, but it sounds easy. Thanks for sharing!

  23. These are so fun! They would be great for a birthday party! I would love for you to share them this week on Thrifty Thursdays link party @ http://fromnature-tonurture.blogspot.com Hope to see you there! Bonnie

  32. Spot on with this write-up, I really believe this website wants a lot more consideration. I’ll probably be once more to read far more, thanks for that info.

  33. What do I do with the creamy mix while I’m waiting for the other layers to set?

  34. Hi, I’m making these in the uk and jello and gelatine come packaged a bit differently. Could you please let me know how many grams are in your packets (envelopes)? Thanks so much!

  35. I do these with sour cream and 3/4 cup of the jello so the layers are not as distinct as yours are but it works nicely too.My layers are probably a little bit thinner.My grown nephews love these at our Birthday parties. I like your version too and will be trying it as well! Always looking for ideas that are different and delicious too.

  36. Very cute. My kids would have love these when they were little. Well maybe they would like them even now.


  37. Wow that was unusual. I jusst wrote an extremely long comment but after I clicked submit my
    comment didn’t appear. Grrrr… well I’m not writing all that over again.

    Anyways, just wanted to say excellent blog!

  38. Carol Cannon says:

    Way too much work for me….. But I’d be happy to pay someone else to make them for me.

  39. I’m a bit confused. Directions say mix 2 unflavored mixed with water to the scm mixture. What do you do with the other 4 pkgs of unflavored gelatin – you only use 1 can of sweetened condensed milk so how do you make 3 batches? Am I missing something?

  40. Momma Bear says:

    Thank you for.helping me rediscover these amazing and beautiful treats! I have been promising my hubby for 6 years that I will make them for him. Neither my mom nor I could could find the recipe.
    My question to you is what do you do with the condensed milk and gelatin mixture while the jello layers are setting? I hate leaving it at room temperature and have never known what to do with it besides leave it out.

  41. sherry lisenby says:

    I learned how to make this over 36 years ago but without the unflavored gelatin. You needed 2 boxes of each jello flavor and a couple more of the canned milk. You made one layer normal them in the second layer made with the boiling water but instead of the cold water you use the condensed milk. Following the same way with the 3 other flavors.

  42. I totally failed while attempting this. Not sure if there is a certain way to use gelatin to get it not to be lumpy but it totally failed for me. Not too sure if I was using the wrong stuff here in Australia? Help!

  43. These cubes look so happy they worth making just to look at them :D My husband wont have them since he knows that gelatine is made of bones….

  44. hi, how much water do you sprinkle the two packages of gelatin over in step 2? Thanks

  45. ooooooh, these are brilliant! I love food that looks pretty! My daughter has a thing with rainbows at the moment, so I think these will be perfect for her upcoming birthday party!!!
