These layered Rainbow Jell-O Squares are sweet, fruity, and completely show-stopping. They require a bit of patience between refrigerating the layers, but the end result is totally worth it!

Rainbow Jell-O Squares

Spray an 8x11-inch baking dish with nonstick spray; set aside. Pour each package of Jell-O into 5 separate bowls. Whisk 1 cup boiling water into each bowl.

Divide berry blue gelatin between two bowls; set one bowl aside. Whisk Greek yogurt into remaining berry blue bowl; pour into prepared baking dish. Cover and chill 30 minutes or until almost set. 

Carefully spoon reserved berry blue mixture into dish over layer. Cover and chill until almost set, about 30 minutes. Repeat steps for each remaining 4 flavors of Jell-O. 

After adding final layer, cover and refrigerate 4 hours or overnight. Cut into 48 squares and serve immediately or cover and store in the refrigerator.
