I have been asked to make a rather different kind of cake and I am really not very experienced at all. I am looking for any help on making a cake that looks like an opened cardboard box...with a head sticking out of the top. I have premade fondant for the box but not really sure how to make it hold up and be stiff enough for a box. Also the head (eyes/nose really), I was going to use a glass batter bowl. Any thoughts anyone could give me would really help! Thank you!

My suggestion would be to cover a real box with fondant to give it a clean look and ensure that it would hold up. You can do the head out of molding chocolate or RKT and do gumpaste features.

Thank you! I am trying to make the whole cake edible but just not sure how to pull it off. I've seen some amazing cardboard box cakes on this site under toy story 3 cakes but I don't know the method. Very beginner and don't want this to be a disaster! How to get the sides of the "box" to stand up a bit above the cake foundation...fondant? Fondant and gum paste mixture? Not sure. Thanks for the tips though!

Try messaging those people directly.... thats the only thing I can think of. Good Luck
