Tips To get uniform baked layers, use a kitchen scale to weigh your batter, then divide that weight by the number of pans you are filling. Place each pan on the scale, press "tare" to reset the weight to zero and weigh the batter's correct amount. Even if your pans seem identical and are the same brand, they may be slightly different in weight.The ratio of chocolate to cream depends on the amount of cocoa butter in the chocolate. For high-quality dark chocolate, 1:1 is a good ratio, while semisweet chocolate with less cocoa butter will require a 2:1 ratio (twice as much chocolate as cream). Ganache can always be adjusted. If too thin, add more chocolate, and if it is too thick, add more cream.Use a turntable to turn the cake as you split it horizontally.For evenly baked layers, make sure there is some space between pans. If rotating the pans, wait until they are about two-thirds baked through to prevent collapsing. How Can Cake Scraps Be Used? When you trim the domed tops, don't throw those scraps away!
