The first thing I made in advance was Thor's hammer and I forgot to take a picture of it before I covered it in fondant. It was made of rice krispy treats with candy melts holding it all together and smoothing everything out. I used pre-made treats again. It worked out perfectly and is way easier than slaving over a big batch of RK treats just to make a 4 inch by 4 inch square.
I always have a great time making cakes for my niece and nephew. Its a labor of love.
My biggest concern was doing the Hulk's face, but I have to say that I did an OK job. This is the picture I followed to get the details right.
Happy Birthday Rydie! I love you!
