Rainbow Jello
March 18, 2008 at 8:20 pm | In Dessert | 125 CommentsTags: class party, jello, rainbow, spring
I was one of the last parents to arrive at school the day the sign-up sheet went up for the Easter Party. Never be the last mom to sign up..the only thing left…jello.
I brought jello last time and really wanted to do cupcakes or cookies or something fun. Reluctantly I signed up for jello, again.
But I didn’t make just jello. Oh no, not me. I made JELLO!
I picked up a 6oz box of blue, yellow and red jello plus a box of knox gelatin. To get these fabulous layers, mix the blue jello with an envelope of the knox gelatin. Pour in two cups of boiling water. Dissolve the gelatin. Add 1/2 cup of ice. Stir until thick. Remove any remaining ice cubes and any bubbles that may have formed. Pour into a 9×13 inch pan. Let set in the refrigerator.
Repeat with the yellow jello and pour it over the set blue. Repeat with the red jello and pour it over the yellow. And there you have it, Rainbow Jello.
I won’t go into the whole primary and secondary color thing, but these colors, when stacked upon each other, create other colors. There is not an orange or green layer. It just looks like it when the red and yellow layers touch and then yellow and blue layers touch. Pretty cool.
Oh, and these can be made and cut a day ahead.

Lovely rainbow Jello squares! What a fun project to take. Good for you for making it funner than cupcakes.

Yes, so pretty, and yes that is not jello, that is JELLO!
Love your photos! This is something my son would love! You make it sound so easy, so I’ll try

I can’t wait for my little guy to start school so I can make these for his class! I want to make them right now but I don’t think we’d eat them. They look so fun!

LOL, I’m bringing napkins. I have had your jello before, and it’s great…even though it’s just jello, LOL!

WOW!!!!!!!!!!! I like it!

Only you could make Jello so fun. Just be thankful you get to bring homemade goodies. Public schools make you BUY everything!

I would have been bummed to get Jello, but you really made it the best of it!
Comment by Allison — March 19, 2008 #
I’m not a jello fan at all. However… that just looks like soo much fun! How could you not be happy to eat that?
Comment by Stef — March 19, 2008 #
Hmm… How can I adapt this for Jello shots?
I agree with a pp. Public schools have really taken the fun out of everything. You can’t bring baked goods but you can bring prepackaged BAKED potato chips – Like those are so much better for you. Weird huh? LOL

Comment by Julz — March 20, 2008 #
those are so cute! I love jello. thats cool that the color just blend like that.
Comment by freepersonaltrainer — March 20, 2008 #
My grandma used to make this, but it was with firmer stripes. I like your way.
You can add cream cheese and condensed milk to make a “creamy” color that mixes well into your stripes, too.
Comment by Amanda — March 20, 2008 #
I love, love, LOVE those photos! That jello is the coolest food ever! Did I mention I love it?
Comment by Madeline — March 20, 2008 #
This is…I mean…that’s just…I’m speechless! I’ve been made speechless by Jell-o! I have seen all sorts of jell-o silliness: jell-o aquariums filled with gummi fish, jell-o flags of many nations, and I even love toying with jell-o myself, although I never got farther than jell-o jelly beans for Easter.
Rainbow knox blox? Genius. Simple. Edible. Pretty. Bouncy. Jell-o.
I can’t WAIT to make this!

The many uses and creative ways of Jell-O are truly amazing. This is so 60’s and 70’s looking … would be great for a retro party!
Comment by Cait Lynn — March 28, 2008 #
I was just wondering… why do u put the knox gelitan in as well… can u get the same effect without using it.. and just use the jello boxes?
Comment by Menaka — April 9, 2008 #
Menaka- the knox really helps the jello squares stay firm. Much more so than a jello jiggler. I haven’t tried this w/o the knox.

Comment by Isabel Kallman — April 13, 2008 #
Found your blog through Design Mom and I LOVE the rainbow jello idea. It’s very similar to knoxblox
but with a few more steps. I think you might love double decker knox blox too. I’ve made them for my kids for years and jello you can hold is always a big hit!! Hope it’s okay to put the link here for recipe & pictures and it works–I’m a still-learning newbie!:)
Comment by Sherra — April 13, 2008 #
This is FREAKING AWESOME.
Comment by maya — April 15, 2008 #
i used to make something similar – but it had three colors, plus alternating layers of a jello-yogurt combination that made them opaque. very yummy and pretty.
Comment by brooke — April 15, 2008 #
Funny, I did the same exact thing and took it to my in-laws for Easter and NO ONE touched it. Doesn’t matter what I bring, no one even humors me with a single bite.

How long did you let the jell-o layer sit before adding the next one?? I would hate to screw something up if i might bring it somewhere!!!
Comment by 422 — April 21, 2008 #
422- it will take about 45 minutes for each layer to set up. Once a layer is firm, you can pour the next layer directly over the top. It will take about 3 hours in total to complete, so plan accordingly. I hope this helps!
Comment by Karen — April 21, 2008 #
If you’ve got 8 hours, and are feeling even more ambitious, try this! Four colours of jello alternated with layers of jelled sweet cream… Yum!

You add an envelope of knox gelatin to each layer, right? Not just the blue (first) one? Maybe a box of knox comes with 3 envelopes but I wasn’t sure by the directions. LOL, it’s been a VERY long time since I made jello. Thanks for the fun recipe!
Comment by Clueless — April 23, 2008 #
Clueless- yep, you add one envelope of knox gelatin to each layer/box of jello. A box of knox comes with 4 envelopes. I hope this helps! Enjoy your jello!

I make 7 layer jello sometimes, and i like to do it in rainbow order. but, the colors sometimes blend together too much. I love this recipe because it creates the illusion that there is a rainbow. plus, it will take much less time than 7 layers! I’ll try this one next time.

My name is Ana Carola Cardenas and I work for the Mexican magazine “Le Fourquet: Gourmet Lifestyle”, one of the publications of the Grupo Multimedios ( http://www.multimedios.com.mx ) in Monterrey, Mexico.
I take the liberty of writing to you to request some high-resolution photographs of JELLO’S Rainbow picture to include them in our magazine. We would love to mention it in our next issue, which will be focused on Colors.

Comment by rafael — May 19, 2008 #
Rafael,
Knox is unflavored gelatin (like Jello, but with no flavor.) It is used to harden the Jello so you can cut it into pieces and pick it up with your fingers.
Comment by Stephanie — May 22, 2008 #
So can you just use any unflavored gelatin then?:) Am not sure I will find Knox in the Philippines.:D
Thanks!

So cool! I made it for my friend, for his birthday party (as addition to my present).
He’s gay and just come out this year…that had good and bad sides, so he was bit under the weather lately…this jello cheer him so much he couldn’t stop smiling.

Do you think it would work if I did Yellow, Blue, and Red, so I get green and purple instead of orange??
Comment by Kaylee — July 14, 2008 #
Kaylee- absolutely! The possibilities are endless.
Comment by Karen — July 15, 2008 #
Thank you Karen! It did work, but with the yellow in the middle it makes it look better, more definite colors. If that makes sense!

wow thats a gr8 way to make jello become JELLO did u think of the idea thow or did u get it of a website. anyway that doesnt matter i decided to try it for myself and it works but i found if you let the colours on ly half set the run into each other more and you can see orange and green way easier and if u put red at the bottom you get purple then when set simply cut the red of from the bottom leaving purple. but to make it even easier for u buy red orange yellow green blue and purple coloured jello cause i know they sell that in australia
