The Cake Slice Bakers, Challenge #2: Sweet Potato Cake with Chocolate Cream Frosting



I was very excited for November's cake for the Cake Slice Bakers: a sweet potato spice cake with chocolate frosting. The name of the cake just oozed autumnality (if that's not a word, it should be). I've had so many other things going on, however, that I put off making this cake until almost the last minute. When I finally got around to making it, it was pretty easy and tasted delicious! It was a new combination of flavors for sure; I would have put chocolate with a spice cake, and I would have put orange with a spice cake, and I would have put chocolate with orange, but I would never have thought of putting all three flavors together. But it really worked. Very tasty, and perfect for the season! I stuck to the exact recipe we were given except I used pumpkin instead of sweet potato. Our grocery store only ever has white sweet potatoes, and I wanted that lovely orange color. To see how other bakers fared with this recipe, click here. And ignore the crazy way this post looks. I couldn't get it right!
