The sizes of the cakes are: 10 x 3, 9 x 3, 8 x 3 and 7 x 3. Baked 2 of each and stacked the 10 on top of the 9 (after carving), and the 8 on top of the 7. Bottom is chocolate cake filled with vanilla b/c and the top cup cake is vanilla cake filled with vanilla b/c. Covered with Fondarific b/c Fondant. Note to everyone: this fondant does not like humidity or heat at all, it literally melted on the way there (my car was very cold, but the move from inside to out was not happy). Made me very sad. Another reason I mix it with Fondx (for stability). BTW, I still love the Butter Cream Fondarific fondant! TFL!
