Sweet Potato Pound Cake with Marshmallow Frosting Recipe

Sweet Potato Pound Cake with Marshmallow Frosting Recipe

This tender spice cake has flecks of sweet potatoes and is so moist that you can dig into it without any frosting. I, however, like a little dollop of sweetness. So, I add a bit of frosting directly on each warm slice. The frosting melts into the cake and it is fabulous. —Emma Chapman, Springfield, Missouri

"This was a huge hit at my Thanksgiving gathering. Everyone really liked cake plain, but the frosting was so good! Frosting takes the cake to the next level. I will be making this again for sure. There wasn't any leftover."

"I was a bit hesitant to try a pound cake with sweet potatoes in it, but it was delicious! Very moist. The cake was still too warm when I put the frosting on so it pretty much slid off down the sides. I was serving it at a church fellowship meal, so I wanted to frost it instead of putting a dollop on the slices. Next time I'll wait until it's all cooled down to put the frosting on because the frosting is delicious."

"I had some mashed sweet potatos in the freezer that needed to be used and I chose this recipe. It was very moist indeed and not overly sweet. I used freshly grated nutmeg so the nutmeg flavor was pronounced and delicious. I elected not to use a frosting as it really doesn't need it."
