Cake Slice Bakers: Sweet Potato Cake with Chocolate Cream Cheese Frosting and Orange Filling


I joined another baking group call the Cake Slice Bakers. Each month we bake a cake chosen from the book Sky High: Irresistible Triple Layer Cakes by Alisa Huntsman & Peter Wynne.

The cake that was chosen for November is a sweet potato cake made with cinnamon, nutmeg, and cloves, filled with orange cream cheese frosting, and topped with chocolate cream cheese frosting.

I was a little nervous how those three flavors would blend together. I considered only making the cake with chocolate or orange, not both. Alas, my husband and muse, convinced me to give it a try. And of course, he is always right about these things (not everything…) and the cake was very good. The cake itself is moist and the spices aren’t overpowering.

The best part, though, is the cream cheese frosting. I’m surprised there was anything left to put on the cake after all the dipping in the bowl that went on. If anything, I have found my new favorite recipe for cream cheese icing.
