A kid pleaser, this rainbow jello is a classic dessert recipe for Saint Patrick's Day, Easter, or for a rainbow themed party. Made with alternating layers of plain and sour cream layers, the result is a beautiful layered jello for a crowd.

Step 1: For 1st layer
Empty 1 small box of Jello into a small glass bowl. Add 1 cup boiled water to jello. Stir until well dissolved.
Add 2/3 cup sour cream and whisk until well blended.
Pour mixture into both glass pans, place in the fridge making sure they are level, and chill until set, about 30-45 minutes.
Step 2: For next layer
Repeat with the same flavor, adding 1 cup boiled water and 1/3 cup cold water to jello.
Let stand for 10 minutes. Pour onto the chilled 1st layer, tilting the pan if necessary to spread, and refrigerate until set.
Continue repeating layers following steps 1 and 2, alternating one with sour cream then one without until each flavor is used.
Once the jello is completely set, slice into 1-inch squares using a paring knife and serve. Using a small spatula will help you get the jello cubes out of the pan. If desired top with Cool Whip.
Keep in mind the rainbow colors, ROYGBIV! Recommended flavors to use: watermelon, strawberry or cherry, orange, pineapple or lemon, lime, berry blue, and grapeThe key thing to have these turn out well is to leave enough time for each layer to completely set up before adding the next one. Trying to rush the process will get you into lots of trouble.The other key to getting nice even layers is to make sure that the dish is placed level in the refrigerator while it sets. If it's not level you'll get wonky layers that won't look nice when cut into.Can I freeze this?NEVER freeze jello! It can be tempting to make this ahead and try to freeze it but when you freeze jello the chemical structure breaks down and the whole thing will begin to melt.This is best made no more than a day ahead as I have found the jello starts to weep liquid after that.
