Maybe it is because of the slew of graduation cakes I made last month but book cakes are one of my favorite cakes to make these days. Check out some examples of graduation and baby shower book cakes I have made then, scroll down for a tutorial on how make and stack these cakes.
To make 1 book you will need...
1 covered cake board
fondant (1 batch)
buttercream icing (2 batches)
tip # 3
cardboard cake divider (optional)
fondant ribbon cutter (optional)
To stack the books you will also need thin foam board and wooden dowels.
Level, tort and stack your cakes. Then, trim the edges to get the desired size of your book. The graduation books are the size of a 2 stacked 1/4 sheet cakes while the baby shower books are made from a 1/2 sheet cake cut into 3rds. Two of the thirds were stacked to make 1 book.
Ice your cake and let set in the fridge for 30-45 minutes. Of course chilling your cake is completely optional but I have found it is much easier to fondant a cake when the icing has been given time to crust.
The best way to lay the fondant on your cake is to let the fondant stiffen up a bit. Then, lay the fondant on a cardboard cake divider and ease it onto the cake as pictured. To make the back cover, cut 1/2 inch strips and lay around the edges of the cake. A fondant ribbon cutter (see supply list) makes this job even easier.
Use your buttercream icing to make the pages by piping lines across the remaining sides of the cake. In this picture I used tip #104 but for and even more realistic look use tip #3. You can see the difference in detail if you look at the books in the very first picture.
Use a gumpaste tool or the back of a small decorating brush to make the details on the binding. Finally, customize your cake with the decorating details of your choosing.
If you are making a stack of books, make sure you dowel your cake. You should also use thin foam board as opposed to card board cake dividers so the book can be supported and won't bend. Notice in the picture below that the board my cake is sitting on is a 1/2 inch larger on 3 of the sides. This was done to give the appearance of a back cover. Later, the edges will be covered in fondant.
