(I did one put the other on top of it and did it.)
Bake a lemon cake as directed on box
Let cool for 10 minutes and then remove from pans to cool completely
After they are cool make jello: 2 small boxes of lemon jello with 1 1/2 cups of milk mix thoroughly and poor onto the top of each cake. Do not let it set before putting it on the cake!
Then you spread cool whip all over as the icing!
Anna added the sprinkles so she could have her flair on it!
