Directions
-
Preheat oven according to cake mix directions and grease two 8-inch or 9-inch round cake pans.
-
Bake the white cake mix as directed on the package instructions.
-
Allow the cakes to cool in the pans for 10 minutes, then remove them from the pans and place on a wire rack to cool completely.
-
While the cakes cool, prepare the gelatin: dissolve each 3 oz package of Jello separately in 1 cup of boiling water, stirring until fully dissolved.
-
Return the cooled cake layers to their respective pans, ensuring the flat side is facing up.
-
Using a fork, prick the cake layers at 1/2-inch intervals all over the surface to allow the gelatin to soak in.
-
Immediately pour one flavor of the prepared gelatin mixture evenly over one cake layer, and the second flavor over the other cake layer.
-
Place the pans in the refrigerator and chill for at least 3 to 4 hours, or until the gelatin is set and absorbed.
-
To unmold, briefly dip the bottom of one cake pan in warm water for 10 seconds. Shake gently and invert onto a serving plate.
-
Repeat the warm water dip process for the second pan and carefully invert the second cake layer on top of the whipped topping.
-
Frost the top and sides of the cake with the remaining Cool Whip.
-
Refrigerate for at least 30 minutes before slicing and serving to allow the cake to set firmly.

Note
For best results, use two different fruit flavors for the Jello to create a "rainbow" effect. Berry and tropical flavors work particularly well.
Ensure the cakes are completely cool before pouring the gelatin to prevent melting or uneven absorption.
If using a single oblong pan, you can split the batter, bake, and then proceed with the same layering technique, or pour both flavors into separate sections of one large pan if desired.
This cake can be made up to 24 hours in advance. Store covered in the refrigerator.
For a vegan version, substitute the Cool Whip with a store-bought vegan whipped topping or whipped coconut cream, and ensure the cake mix and Jello used are certified vegan (some Jello brands contain gelatin from animal sources).
