This is going to be my first ever wedding cake. Usually I would make one cake for each tier, then slice each cake in three and fill with buttercream then restack. The tiers in this cake look a lot taller though so I'm not sure I would get enough height my way.
Any advice would be appreciated!!
A standard serving is 4" high. If you are going to do any taller than that, make sure you use supports at every 4" of cake.
I generally make 2 layers for each tier, and separate them with a layer of filling or frosting. But you could make 2 layers, split each one, then put in 3 layers of filling/frosting.
The standard is a 4" high cake. For most people that involves two layers for each tier. That said, the more you torte it, the more wonderful fillings and flavors you can get in the cake! Also, many people think, and I agree, that for a wedding, all of those layers of filling and cake look nice.The extra filling can also boost you solidly above the 4" mark, giving the cake a nice height for presentation.
Also, two layers bake faster than one really thick layer. So unless you have a design reason or a special request, shoot for a 4" high tier, torted as many times as practical.
