  • Total Time: 4 hours
  • Yield: 9x13 pan- 24 squares 1x


  • 3 oz box of jello in the following flavors: lemon, lime, orange, cherry or raspberry, blueberry, and grape.
  • 1 cup boiling water for each flavor
  • 2 cups sour cream or greek yogurt
  • 12 Tbsp cold water
  • whipped cream or cool whip topping


  1. Spray 9x13 pan (*aff. link)   and set aside.
  2. The key is to make one layer at a time.
  3. Start with red. Boil 1 cup water and add it to the cherry jello powder. Stir will. Then, divide that in half into 2 bowls.
  4. To one half, add 2 Tbsp. cold water.
  5. To the other half, add 1/3 cup sour cream and mix until incorporated.
  6. Pour the cherry gelatin with cold water into the pan.
  7. Refrigerate for at least 20 minutes.
  8. Then pour the red jello with sour cream onto the first red layer.
  9. *Then, you will just repeat for all the layers. You can do them in any order, but I prefer red, orange, yellow, green, blue, violet.

To recap: 1st layer: red jello with water; refrigerate 20 minutes; 2nd layer: red jello with sour cream; refrigerate 20 minutes; 3rd layer: orange jello with water; refrigerate 20 minutes; 4th layer: orange jello with sour cream; refrigerate 20 minutes.

  1. Repeat for all layers. Right before serving, top with cool whip or whipped cream.
  2. *Make sure the jello you are adding is cool so that it won't melt the previous layer. To speed up the process, you can make two flavors at a time and let the other one cool while the first one is setting up.
