About this recipe: A great alternative to spiced pumpkin cake. This cake is flavoured with sweet potato, cinnamon, allspice and ginger. It's incredibly moist and will work well with a cream cheese or buttercream icing.
I made this cake twice and each time the people I served it to said it was delicious and moist. I didn't make them in two separate pans but in a single 9" spring form pan and baked it for 40 minutes instead of 30 minutes. Another thing I did do the second time around was whisk together the mashed potato and the milk to blend it more evenly as the first time the potato was more clumpy. I also reduced the white sugar to 1/2 a cup as I found it a bit too sweet. - 13 Mar 2006 (Review from Allrecipes US | Canada)
Wow! This was a pleasant surprise. It tastes a lot like carrot cake, but different enough that you can tell it is _not_ carrot cake - prompting enquiries of, "What the heck is in here?" No one ever guesses potatoes! This takes about 2 or 1.5 regular sweet potatoes. The batter is wonderful and will make a cake with two layers nicely. Mine did sag a bit in the middle after cooling but were still great. I frosted with Caramel Frosting, which I just realised now I forgot to add the vanilla to. A chewy moist cake that keeps well. - 19 Mar 2003 (Review from Allrecipes US | Canada)
Cake turned out light, moist, and delicious. I didn't have dark brown sugar on hand so I used light brown. Couldn't find the allspice so I used nutmeg instead. I increased the amount of sweet potatoes to 1 1/2 cups and added a cup of sour cream for extra moistness. I frosted the layers with cream cheese frosting. This cake has the perfect texture with just the right level of spice. This one's a keeper. - 05 Jun 2009 (Review from Allrecipes US | Canada)
