I had posted this a long time ago on a message board that I no longer participate in. It is INCREDIBLY image-heavy, so I’ve put everything behind the cut. A few warnings - first of all, this “recipe” is INCREDIBLY time consuming. There are 30 minutes of “gelling” time between each of 12 layers. The recipe isn’t complicated at all - but if the jello isn’t ABSOLUTELY firm, the colors will get muddy. . I went back and edited the post for clarity And so, without further ado:
Ingredients:
3 oz boxes Jello. I used cherry, orange, island pineapple, lime, berry blue, and grape
32 oz container Vanilla Yogurt or Sour Cream 32 oz is more than you’ll need for this recipe, but IMO too much on hand is preferable to running out mid-recipe.
Boiling water I just fill my big pot, set it to boil, and measure out the water as I need it.
Basic procedure:
Dissolve 1 package Jello with 1 cup water. Mix 1/2 cup Jello mixture with 1/3 cup yogurt and set aside.
To remaining Jello, add 2 tablespoons cold water and pour into your chosen pan. I used a 9 x 13 plastic pan, but you can also use a bundt-type pan.
Chill 30 minutes.
Pour “creamy” jello mixture over clear layer, and chill for another 30 minutes.
Repeat these instructions for each color. Once you have the clear layer in the fridge and the creamy layer waiting, go ahead and dissolve the next color in 1 C boiling water. This will give it time to cool, avoiding the hole that I made in my example.
Step 1 - gather your ingredients - Vanilla yogurt, whipped topping, and jello in rainbow colors. Curse vilely when you realize that the 9×13 CLEAR pyrex pan broke and that you’ll have to use the not NEARLY as cool Tupperware 9×13 plastic box.

Bring a pot of water to a boil

Add 1 C of boiling water to jello package and stir til dissolved:

Measure out 1/3 C of yogurt

put 1/2 C jello &2 Tbs. cold water into 9×13 pan and stick it in the fridge. Curse the fact that your house (or the fridge) isn’t level and stick a hotpad under the dish in a pathetic attempt to level it.

Mix the remaining jello with the 1/3 C of yogurt and stir well. Leave on the table @ room temperature for 30 minutes (until the plain jello is done).

Realize that your hands are shaking because you forgot to eat breakfast and nuke a Tasty Packaged Meal

When the timer goes off, pour the yogurt jello over the plain jello and stick it in the fridge for another 30 minutes.

This concludes the PURPLE layer. Yes, I do intend to document the remaining 5 layers in similar style, so if this is enough, either stop reading, or scroll to the bottom to see the Finished Product.
BLUE LAYER:
When the timer goes off signifying the last purple layer has solidified, go ahead and make the blue jello. Realize that the blue jello you just made is going to be too effing HOT to pour directly onto the purple layer, and that it’ll melt. Rejoice as The Mom walks in the door, and ask her to take the oh-so-COOL shot of you cleverly pouring the hot blue jello over a spoon to help deflect the pour. Get REALLY pissy when she says “I don’t know how to work this blasted camera, and that jello looks like a big waste of time to me anyways!”. Do without the cool shot, curse under your breath as you slosh the blue jello around to keep it from melting, and stick the damn thing in the fridge without taking a pic.

Tell your youngest to stack the boxes, then realize he’s STILL in his jammies.

Get Smart this time, and make the Green Layer so it can cool off while the blue solid layer is setting up in the fridge.

Next up: The GREEN Layer
OK, here’s the first blue layer (see the hole in the middle?)

And here’s the light blue layer

Here’s the green layer going on (now you can REALLY see how lopsided it is)

And the light green layer

Up next, YELLOW!
Mmmmmkay. Here’s a bunch at once, it’s the next-to-last post
This is the light green layer, solidified, with yellow standing on deck in the background:

The yellow layer proved to be too light to photograph from the top, but here’s the light yellow layer

AND NOW for the reviews:
Iwouldn’tmakethatittakestoolong Mom - WOW!!! That’s AMAZING!
DD (13) - Mom. That. RAWKS.
DS2 - *insert vacuum sound here*
DS1 - doesn’t like jello
PS: Hi and welcome to the folks from Tipnut and StumbleUpon!






I despise jello and all the things it jiggles for.
but
I’m so totally going to the store to get stuff to make that!
OK, so how long did it take you to make this, and can you use sugar free instead of sugary jello? I totally want to make it. Oh, and what was the hole in the middle of the blue for?
nuala, the hole in the middle of the blue is accidental. The blue jello was too hot, and melted a hole almost completely through both purple layers. I haven’t tried it with sugar-free jello (I try to keep aspartame out of the kids’ diets), but I would think it works the same way. This was an all-day project (I made it Saturday with the intention of serving it for dessert after Sunday dinner), but the most time-consuming part is the waiting between layers, so I was able to do other things at the same time.

James that is one huuuuge pic. Thanks for your comment though!
