Cut and fill your cakes Ganache or buttercream your cakes trying to keep the edges as sharp as possible on one side. The other side can be rounded as this is where the spine of the book will be.
Fellow Pettinice Ambassador, Sharon Wee has created a Youtube video on how she creates sharp edged square cake foundations. You can watch it here.
At this point, it is easier to set up each individual book on it's own cake board and place it on top of baking paper to move it around the bench easier.
Measure the width and full length of the side of your book. For a seamless look, roll out a long white strip and adhere to the cake by wrapping around. There are three ways to give the fondant the look of having pages:
I usually let the icing firm up overnight at this point, but if you don’t have time just move on to the next step.
Bottom covers. Roll out a thick rectangle of fondant and cut one complete straight edge. This straight edge will sit on the inside bottom book cover (see photos that follow).
Have this fondant on baking paper for top tiers, or directly onto your final cake board. Be sure to roll your shape larger than your cake. Brush this piece with piping gel. Place your ganached cake (with the cake board) on top, remember to leave the straight edge under the cake slightly so you can tuck the cover to meet in later.
Trim back the sides of the fondant book cover, leaving about a 5mm overlap.
You can add tylose to your fondant, however I have never needed to.
Measure the total width and length of your two remaining exposed sides. This will give you an idea of how big to roll your next piece of fondant for the cover.
Trim your fondant piece, remembering to add 5mm overlap around all sides. You can leave a bit more excess and trim down later, leaning on your plastic sheet as you trim.
IMPORTANT NOTE:
At this moment, you don’t want to adhere the fondant to the top of the cake. Wait to brush a bit of piping gel over the top of your cake just before the fondant will wrap around the spine. First, wrap your fondant around your cake leaving a small peep through the spine of the book and tuck it under your cake.
Grab your clear plastic sheet and pop under your top fondant. This will ensure your fondant dries straight giving your cake a cleaner more realistic look.
Trim any parts that have stretched or if you haven’t done already trim your book cover down, using your plastic sheet to stabilize. If your fondant is sticky you will need to put baking paper between the fondant and the clear sheet or at least a bit of corn flour so you can easily slide it out later.
This is your chance to play and create your book details. Indent your cover and spine with a ruler and some cool rubber stamps if you have some. Repeat the same process with your other books ensuring they all still sit on baking paper so they can be easily moved later. Put aside and allow cakes to set.
Using hard plastic sheet is my trick for drying these fondant book covers
Let these cakes sit overnight to give them a chance to harden up to get that clean look without floppy cover edges when it is time to stack.
Now that your books have firmed up, you can add shading to the pages with a mix of black and brown petal dust and corn flour. Start off light and go darker. Paint your top cover and spine of your books with a mix of good quality vodka and petal dust or gel colours.
Melt some chocolate and adhere your first book to your base board. Add your doweling or staws to you bottom and middle book, this will support the weight of the books you are going to stack. Again add chocolate to the top of your first book and place on your second book insuring it is slightly twisted so it looks more interesting. Add your last book.

I love doing animals especially."
