For your Mom, this is the ultimate treat. At her surprise party, she will be pleasantly surprised when she sees you standing there with a homemade surprise cake that is all her own. Made a surprise cake for mom she will be surprised and happy with this cake. I wanted to give my mom something so that she can always go back to her and say "I was so happy that I got this for you".
