Friend wanted 1/2 butter cake and 1/2 strawberry and only wanted a 9x13 size. So I just went ahead and make two (2) 8x8 cakes and placed them side by side. All frosted in buttercream with fondant decorations. Was very excited since I just got the Funky Letters stencils. Those stencils are just great - only it works best with gumpaste. I used 1/2 fondant, 1/2 gumpaste and it worked very well.
