I made the mistake of showing my daughter a picture of something like this months ago and she stored it away in the back of her brain. She's that way.
When we were planning her birthday party, a Wizard of Oz one, she decided that she must have a rainbow cake and rainbow jello.
This is the part when I kick myself for showing her in the first place.
It is time consuming to do this, but sooooooo cool that it's totally worth the effort.
HOW COOL IS THIS?!?!
- 6 oz packages (or two 3oz if you can't find the 6oz size) of 6 flavors of jello, in the colors desired
- 1 can sweetened condensed milk
- non stick cooking spray
Set aside a good two hours for this project. And clear out of shelf in your freezer that will fit a 9x9 baking dish flat. It has to be flat, like completely. You will see even the slightest angle in this.
Using a 9x9 dish that ideally has squared corners, spray it on all surfaces with nonstick spray. Set aside.
Make the purple jello with 1 cup of boiling water. (Do not follow the regular recipe or the jigglers recipe, this is different). Add an ice cube to speed the setting process up a little. Pour 2/3 of the purple jello in the baking dish and place in the freezer for about 5 minutes.
Meanwhile, add about a teaspoon of the sweetened condensed milk to remaining purple jello and stir thoroughly.
Carefully remove pan from freezer, making sure the first layer has begun to set. If it is still a liquid, put it back in for a few more minutes. If it has firmed a bit, carefully spoon the purple jello mixed with the condensed milk over the top in a thin even layer. Put back in the freezer while you start preparing the blue jello.
Repeat for all the colors.
When you have all 12 layers complete, the 9x9 dish will be full just to the top. Put it in the fridge to chill for at least 3 hours (overnight is ideal).
To cut, you are best to remove the entire thing from the pan at once. Run a sharp knife around the edge and carefully wiggle it out. If you've sufficiently coated the pan with nonstick spray, this should be fairly easy. Spray your knife with nonstick spray and cut into cubes.
Share and smile. :)
