I made this Batman cake for my grandson’s 5th birthday. The blue cake was lemon filled with lemon curd buttercream and the yellow one was an almond white sour cream cake. The Batmobile was made out of Rice Krispies, fondant and gumpaste! My grandson chose the design of the round cake from the internet – so even though I don’t have the name of the person who originally did this cake – I thank you because you made my grandson a very happy boy!
