It was 3 tiered, covered with buttercream and marshmallow fondant followed. The horses I piped with color flow a few days in advance, and attached with royal icing. The other details are all fondant or royal icing. To get the pointed dome top, I used one of those giant cupcake shaped cake pans, and baked a little cone shaped cake in the top half, then placed it on top of a regular round cake.
I was pretty pleased with how this cake turned out! And most importantly, all the guests at the party remarked on how good it tasted {I do boxed cake mix & make my own buttercream using Serious Cakes recipe!} The lines weren't all perfect, but this was by far the most complicated cake I've made to date, so I'll go easy on myself.
