My sister asked me to make her wedding cake and I am beginning to start my research. Although I have catered several events before I have never made a wedding cake. I have mastered Swiss buttercream frosting and the lemon curd but I am a little nervous to make a tiered cake. Sure I've made plenty of 8 or 9 inch cakes, but throw in a 12, 10, and 8 cake, I'm lost on the ingredients and the cook times! Is there a layer cake cookbook or blog that features how to make a wedding cake you would recommend?
