We celebrated Danika’s Birthday this year with an epic rainbow unicorn party and this stunning rainbow jello was the star of the show! The kids always get to pick their theme and I think it’s become a favorite thing to do. I then take it and run with it! I’ll be sharing all of my ideas from her Rainbow Unicorn themed party and I had to start with my favorite (and the most awe-inspiring thing at the party), Rainbow Jello! It looks difficult, but while it is time-consuming, it is NOT difficult!

 

This rainbow jello is stunning and while it looks difficult to make, it's easy! These are easy to follow step-by-step directions! Perfect for your next rainbow party or holiday gathering!

Rainbow Jello

This Jello turned out beautiful and was the talk of the party! If you are looking to bring a dish to your next party that will wow the crowd then this is it! If you are planning a rainbow party then this rainbow jello is the perfect rainbow food to serve to your guests! It may look incredibly difficult to make, but rest assured that this recipe is NOT difficult! It’s quite easy if you follow my simple step-by-step instructions. Keep in mind that this Jello takes an entire day to complete since you’ll be doing the layers one at a time and allowing them to set. Give yourself plenty of time to make it and don’t rush it! I would advise making this the day before your party or gathering. It will hold up just fine in the fridge!

Rainbow Jello Recipe

The trick to making the rainbow jello turn out beautiful is to create thin layers and let them set completely before pouring the next layer. It’s very important to follow the directions exactly and let each mixture cool enough so that it doesn’t end up melting the layer below it when you pour it on. If you rush it and pour the next layer on top of your jello before it is set then you’ll end up with layers that run and are mixed. It will still taste fine, but it won’t achieve the layered look you are aiming for.

Rainbow Jello Supplies

If you are planning on making this rainbow jello then make sure you have these ingredients on hand or order them now so you are ready to make this beautiful rainbow jello!

6 small packages (3 ounces) of different Jell-O (I used rainbow colors however you can use as many or as few colors as you’d like and you can change them up for holidays)
4 packages Knox unflavored gelatin (I recommend buying it in bulk in a can instead of all the little boxes-it’s cheaper that way)
1 (14 ounce) can Sweetened Condensed Milk

You’ll also need a glass 9″ x 13″ pan or casserole to make this rainbow jello in.

Rainbow Jello Instructions

First layer: Mix 1 package of any flavor jello with 1 tsp Knox gelatin and 1 cup boiling water. Cool and pour into pan; refrigerate until set. Ensure that your fridge shelf is level so your layer sets evenly and doesn’t turn out thick on one side and thin on the other. It takes about 30 minutes to set up in the fridge before you can move on to the next layer. *Important* While waiting for your Jello to set, make the next layer and leave it to cool on the countertop.

Second layer: Mix 1 envelope Knox gelatin (or 2 tsp Knox if using the bulk can) with 1/2 cup hot water until dissolved. Add 1/2 can condensed milk and an additional 1/2 cup hot water. Once cooled pour 3/4 cup (just enough to cover the Jello and make a thin layer) of the milk mixture over the set jello and refrigerate until firm. It takes 30 minutes for this layer to set up in the fridge. As soon as you put the white layer in the fridge to chill make the next color jello so that it will have 30 minutes to cool on the counter.

Repeat first and second layer directions ending with a color jello layer. Half way through the process you will need to make the other half of your white mixture. The first time I made this I made the white layer all in one batch and ended up with a bowl of jelled white mix before I was done because it takes so long for the layers to set. If you find this happens to you then set your bowl of white mixture in another bowl of hot water (underneath it so it’s not mixing with your white mixture) and it will dissolve and liquify again.

Once you run out of white mixture then Mix 1 envelope Knox gelatin (or 2 tsp Knox if using the bulk can) with 1/2 cup hot water until dissolved. Add the other 1/2 can condensed milk and an additional 1/2 cup hot water. Once cooled pour 3/4 cup (just enough to cover the Jello and make a thin layer) of the milk mixture over the set jello and refrigerate until firm. Continue repeating layers until you are done.

*NOTE: I made my white layers thinner than my colored layers. Some readers have commented that they ran out of white mixture. If you make your layers thicker then you will run out. You may want to have a second can of sweetened condensed milk and an extra box of plain gelatin on hand in case you run out!

Once finished, cover with plastic wrap and refrigerate overnight to set until firm. Then slice into rectangles or squares and serve! Not only is it beautiful, but it tastes great too!

This rainbow jello is stunning and while it looks difficult to make, it's easy! These are easy to follow step-by-step directions! Perfect for your next rainbow party or holiday gathering!

I began my layers with purple then blue, green, yellow, orange, and red so they would be in correct rainbow order. Remember Roy G. Biv! Red, Orange, Yellow, Green, Blue, Indigo, Violet. We skipped indigo 🙂 In order for them to be red on top, purple on bottom, we started with purple and worked backwards. Of course you’ll also have a layer of white in between each.

Ingredients
  

  • 6 small packages 3 ounces of different jello colors
  • 5 packages Knox unflavored gelatin or buy a bulk can to save money
  • 2 14 ounce can sweetened condensed milk
  • Water

Instructions
 

  • You will make this in a glass 9x13 pan.
  • First layer: Mix 1 package of any flavor jello with 1 tsp Knox gelatin and 1 cup boiling water. Cool and pour into pan; refrigerate until set. Make sure your pan is on an even surface so your layer is level. It takes about 30 minutes to set up in the fridge before you can move on to the next layer. Important While waiting for your Jello to set, make the next layer and leave it to cool on the countertop.
  • Second layer: Mix 1 envelope Knox gelatin (or 2 tsp bulk powder) with 1/2 cup hot water until dissolved. Add 1/2 can condensed milk and an additional 1/2 cup hot water. Once cooled pour 3/4 cup (just enough to cover the Jello and make a thin layer) of the milk mixture over the set jello and refrigerate until firm. It takes 30 minutes for this layer to set up in the fridge. As soon as you put the white layer in the fridge to chill make the next color jello so that it will have 30 minutes to cool on the counter.
  • Repeat first and second layer directions ending with a color jello layer. Half way through the process you will need to make the other half of your white mixture. The first time I made this I made the white layer all in one batch and ended up with a bowl of jelled white mix before I was done because it takes so long for the layers to set. If this happens to you just immerse the bottom of your white mixture bowl in hot water until it liquifies again.
  • Once you run out of white mixture then Mix 1 envelope Knox gelatin (or 2 tsp bulk powder) with 1/2 cup hot water until dissolved. Add the other 1/2 can condensed milk and an additional 1/2 cup hot water. Once cooled pour 3/4 cup (just enough to cover the Jello and make a thin layer) of the milk mixture over the set jello and refrigerate until firm. Continue repeating layers until you are done. Recipe note: Some readers ran out of white mixture. If you make your white layers too thick you will run out. They should be a thin layer. You may want to have an extra can of sweetened condensed milk on hand just in case you run out!
  • Once finished, cover with plastic wrap and refrigerate overnight to set. Then just slice into rectangles and serve!

Notes

I have included an extra plain gelatin and sweetened condensed milk in case you run out as some readers have.

    Great recipe- the only glitch was there was not enough of the condensed milk mixture to do one in between each of the six colors. I had to go back to the store to buy another can of the condensed milk- that or decide to skip the orange. After several hours of this, I was not going to settle for anything less than the picture.

    This is really neat looking, but I wonder at my ability to pull it off! I’m going to try, but it seems like one of those things where you end up with the “this is how it’s supposed to look” pictures next to the “my result” picture that looks like someone stepped on it… (I’m not crafty in the kitchen… )

      Once it has set it holds the consistency like Jell-O jigglers would. Not sure if you have an issue with those or not but I would just keep it on a tray of ice (ice underneath the tray).

    Can we make this in a jello mold?

    Reply
    • Windward Wahine says

      March 9, 2014 at 9:53 pm

      You can make it in any mold. However, I suggest you use clear molds so you can see the layers as you pour since some of the readers run out of the milk layer. Depending on your mold, your milk layers will not equate to the same measurements as the colors. My mom made this when I was growing up and then I took over as a mom myself. What is not explained are some errors, that if you wait too long to pour layers, the layers will not stick to one another then when you slice the layers split when eating pieces. I made this mistake among pouring too quickly and the layers below melted too. It is 5 hours or more depending on your fridge…but it’s constant and you should not be interrupted. also to cool jello faster don’t leave in same pan to cool, I suggest pour off into glass measuring (some plastic stains) cup to cool. If you just happen to pour too hot and it melts, don’t fret, it will taste the SAME, just adds character. no need to toss out and start over, just keep pouring till you are finished. this happened to both my mom and myself and we just let it go and it turned out pretty good because it created unique designs in the Jell-O. Once again, it tasted ALL the same…just yummy

        Thanks for the additional tips! And as for some running out of the milk layer, I made mine thinner than the colored layers so that could explain why 🙂

    A tip: make sure your pan is on a perfectly level surface while setting. Apparently the shelf in my fridge is off kilter, which I didn’t realize til I poured my first white later and discovered it to be thin on one side and thick on the other, oops! So I put a kitchen magnet under one side to raise it up to even out a bit. Not perfect but tastes the same anyway haha.

    Wow! These are totally amazing! (Already pinned on two boards) They look like impossibly difficult to make for anyone who isn’t at least a professional dessert-maker. Never the less ~ I am going to take it on and master it for a very specially member (the patriarch really) of our extended family – whose lovely house we traditionally all have Thanksgiving dinner at.

    Each of use is responsible for bringing certain dishes for the big dinner I always make several of my specialties (sides appeitizers and one of the dessert pies)… But I want do do something special for our special host who is turning 95 this month and who absolutely LOVE JELLO / Jello Molds (he’s a retired OB-GYN – who love jello) and this is about the most impressive Jello masterpiece I’ve ever seen!

    If I can pull it off ~ and everyone else at the table will be DAZZLED! Thanks!

    • Sarah Must Have Mom says

      August 27, 2015 at 9:19 pm

      Sorry for the confusion. You use 1/2 of the can with water and gelatin to start. Then once this is used up you will use the other 1/2 of the can. If you use the while can at once and mix it all up, it will set before your layers have time to fully set up. Hope that helps!

    I am surprised no one has commented about the incorrect instruction of the white layer. This set of instructions is either incorrect or misleading:

    Second layer: Mix 1 envelope Knox gelatin with 1/2 cup hot water until dissolved. Add 1/2 can condensed milk and an additional 1/2 cup hot water.

    This is way too much water and the white layer will not set. I tried to make this for my daughters birthday party and the whole thing was ruined.

      I’m so sorry this didn’t turn out for you. But I did use one cup total of hot water for this step. The instructions are correct. Did you make sure the gelatin was dissolved well? That could lead it to not set up.

      It sounds like it is the gelatin setting up too fast. Only make half the white mixture at once and work as fast as you can.

      I haven’t tried it. As long as the boiling water is enough to dissolve the gelatin and you make sure to give it time to cool completely, it may work.

        I a tually make one comor in advance to help shorten the set time. So, when I do the purple later for instance, I also prepare the white AND the blue color. They will cool some but do not set. If they so start to set, you can always put in the microwave for 10-15 seconds to warm it up just keep an eye on it! This helps dramatically with the setting time!

    Can these beautiful layers be done in a large glass truffle dish? I would have to transport to the event in a ready to serve fashion, and was thinking a triffle bowl would transport easily while still being able to see the beautiful colorful layers.

      I don’t see why not. I would just make sure if your trifle dish is larger than a 9×13 pan that you increase amounts to account for the extra volume.

    Hello! I am curious, in the recipe it says to add 1 tsp of the Knox gelatin to the Jello, but the gelatin comes in 0.25 ounce packets. Should we be pouring out a few packets into a bowl then measure 1 tsp from there?

    • Sarah Must Have Mom says

      March 2, 2017 at 11:03 pm

      Yes, I measure 1 tsp from the packets as needed. For every other layer you will use a whole packet of the gelatin.

    I love this idea! Got to keep this in mind for my Grand Son’s next birthday! It reminds me of the X-Mas Ribbon candy during holidays!

    I just made my white layer, but it’s not white! I used Eagle Brand sweetened condensed milk, and its a light caramel color. What’s the deal?

      I just dipped the bottom of the pan into warm water to help release it and then I sliced it and used a silicone spatula to scoop it out.

    Hi! My daughters party is on a Saturday and I work full tone. Do you think it would be feasible to make this on the Thursday evening before and keep it in the fridge? Also – you mentioned you dipped the bottom of the 9×13 pan in hot water to get jello to release. What did you dip it in that was large enough for the 9×13 pan to fit in and how long did you dip it for it to release? Thank you!!!

      Yes it will keep just fine in the fridge until the party. I use a shallow pan with hot water to dip the bottom of the jello pan in. Just dip it for 15-20 seconds and if it doesn’t release then dip it again until it slightly melts and releases. Have a fun party!!

    My grandkids help make this for party. It is simple to do we followed your instructions to the T. We ran low of the filling part and instead of making a whole new batch we left out blue. No one noticed :>) We put My Little pony toothpicks into each for one party and left them out when we took the leftovers to another event the next day

    Yeah like others have said I’m low on the filling which is incredibly frustrating because I’ll have to make a special trip to the store tomorrow to buy more. There needs to be at *least* a cup for each layer and maybe more. In fact, I can’t even see it in my pan as the second layer and my 9×13 is just shy in dimensions of a 9×13. The first layer doesn’t show on the sides either so I’m not sure how this will look but there definitely needs to be more filling unless you mean a 6×9 dish. But there doesn’t seem to be enough jello either so far, but I’ll have to wait on that. It seemed to barely cover the bottom. I checked the recipe multiple times to be sure it’s not a user error.

      This ended up coming out mostly okay, but I definitely needed double the gelatin and sweetened condensed milk, and I even still had to kinda tilt the pan around a bit to get each layer to cover the bottom. I had the extra can of sweetened condense milk as suggested, but I bought one pack of gelatin (not the bulk) so I had to go out and buy an extra box. I used like 8 packages… so PLEASE advise people to definitely have extra of both on hand, not just extra sweetened condensed milk on hand.

      I also was able to significantly speed up the process too, but one would need a digital kitchen scale (honestly though if you bake, it’s a lifesaver and will save you a ton of measuring tools and be more precise. No more annoying flour measuring!).
      I used 3/4 cup of boiling water to completely melt the jello powder, and then the equivalent of 1/4c water in crushed ice from my fridge dispenser. (I don’t remember the amount, but I weighed 1/4 cup of water and then just did the equivalent in ice chips). This SIGNIFICANTLY hastened the process as it cooled and even thickened the jello before pouring it onto the layer, and then I popped it in the freezer for not even 10 minutes. This was the perfect ratio: enough boiling water to easily melt the powder, and enough ice to cool it completely, melt the ice chips completely, thicken it slightly, yet not completely set up. If you’re gonna make this, I really suggest this method as it will save you a ton of time (unless you plan on spending all day in your kitchen). Everyone at Easter was impressed by how it looked (even though the first few layers were uneven because of testing pour amounts). But next time I definitely know how to do this better. haha

      Hi Kat! Sorry to hear you had issues with the quantities of liquid. Each layer should be thin as you need to fit all the layers in the pan. It should just cover the previous layer and not much more. The white layer is meant to be a very thin dividing layer. I have updated the post to suggest having an extra sweetened condensed milk and gelatin on hand. I’m sorry you had to make an extra trip!

    I made this for a spring bbq, and everyone loved staring at it! And everyone of all ages insisted on trying it. One tip – pour the next layer while the prior one is still sticky, otherwise they will peel / fall apart when you lift out the slices. Thanks for the great instructions!

    Hi there. thanks for the recipe. One snag amateur-cook-me ran into is that it doesn’t work very well to add water and milk to gelatin. You have to pour the powder into the liquid. Otherwise it just all gels at the bottom of the bowl, even after stirring.

    Hi, did you purposefully only use one cup of water when making the jello? Packet instructions say 1 cup of boiling and then 1 cup of cold water. Making it this weekend so just want to make sure.
    Thanks 😊

    Hi, I want to make this in the UK- for our Jello you usually use 1
    Pint hot water. Any ideas how to adapt the quantities? Does your recipe use less water than the pack suggests and extra geletin so it’s firmer? Thank you!

    The recipe worked great, except for the white layers being so very thin you could barely see the distinct layers. Also could you edit your terminology for the Knox gelatin. In baking, the term is envelope for the individual paper packing (within the gelatin box itself). The ambiguity of the terminology made it so I bought four packages or boxes, way more than needed. I have used Knox gelatin before and knew there were four envelopes inside but packages had me confused.
