Yes! You can easily make this cake as written and divide the batter into two 6 inch (15 centimeter) pans for baking. This will make a narrower, somewhat taller cake that doesn't require torting (cutting the cake in half horizontally). The bake temperature should remain the same. Start checking for to see if it's done 5-10 minutes earlier. Use the ganache recipes as written. You can either apply a thicker center layer of whipped ganache, or divide it and put some on each cake layer. If using it on the top layer of cake, carefully level the whipped ganache to provide a smooth surface for the ganache glaze.
