This was design by the bride-when first approached,the cake in the sketch looked like two 4" cakes and a larger(in diameter) tier on the bottom. What eventually transpired was this. The cakes from top to bottom are: 6" double barrel,8" double barrel,single layer 12" diameter,18" double barrel cake dummy.All except the 2" layer are done in buttercream! The flavor from top to bottom was vanilla caramel(My new fave:LorAnn caramel)4 dozen cuppies with fondant roses accompanied the cake around the base. The venue is an art gallery.TFL!!
