1 package Orange Supreme Cake Mix
12 oz. prepared Whipped Topping
16 oz. Sour Cream
1/2 cup Confectioners' Sugar
1 small package Orange Jello
Prepare the orange cake according to directions on package, and bake in two 9" round pans. When it's done, cool the cake for 10 to 15 minutes in the pans, then remove and allow to cool completely on wax paper. When the cakes are cooled, slice each in half to produce four round layers.
Meanwhile, blend together the prepared whipped topping, sour cream, and confectioners' sugar in a large mixing bowl with a hand-held mixer.
Place the first layer of the orange cake on a serving dish. Cover generously with the whipped frosting.
Repeat the process with the other layers, making sure to use the white frosting between all layers except the top one.
Mix at least half of the Orange Jello powder into the remaining while frosting. Cover the top layer and the sides of the cake with it. Chill to store, slice to serve. Make sure to keep any leftovers refrigerated.
