Carrot cake is carrot cake. Some people make it too dry, some too moist, other in between. The real test is the butter-cream cheese icing. If that isn't right then no carrot cake tastes good.
Buttercup Bakery! The cake is perfectly moist, the cream cheese frosting is a a creamy and consistency, yet not too heavy.
