Mix and bake cake according to box directions. While cake is still hot, poke holes all over the cake with a fork. Mix jello according to package directions and very slowly pour all over the cake. Let is soak in good and cool. Mix the vanilla pudding and milk let set up a little and fold in the whipped topping. Frost cake then lay the sliced strawberries on top.
The cake is blue, the frosting is white and the strawberries are red. Everyone raves over how great this is and I've had to start making 3 or 4 for the 4th of July parties!
