I love butter cakes. They are simple and sweet. They taste great for breakfast or an afternoon snack.  I saw a recipe for a pumpkin butter cake on Table for 2…or more. The cake looked so delicious. I knew I had to try it.

I don’t have any pumpkin so I decided to try making a version with some sweet potatoes. Specifically, I decided to use a Japanese sweet potato, called satsumaimo, which has yellow flesh and a purplish red skin. This type of sweet potato is more starchy than the common ones found in American grocery stores. They are also very sweet. I always find yams to be too runny and wet, so I prefer these Japanese ones because of the starchier texture.

The cake came out beautifully. The outside crust had an almost sugary crunch. The inside was soft, smooth, sweet and oh so delicious. This cake didn’t last long.photo of two slices of cake on a plate

I definitely will make it again and I’ll try the pumpkin version once when I get some pumpkin.
