You can bake this cake in quarter sheet pans for a rectangular cake or keep round layers whole for a traditional cake presentation. Do try the cake; it is spectacular. While it pairs beautifully with the eggnog frosting, feel free to use your favorite carrot cake frosting recipe. The flavor of this cake is fantastic. Perfumed with warm spices and nutty brown butter with just enough salt to make it all shine. So moist and delicious. See the notes at the end of the recipe for ideas for more inclusions.
