Years back, I attended a baking retreat hosted by Martha White with my buddy Brandie from The Country Cook. While there, we were tasked with creating a recipe using Martha White’s sweet potato muffin mix. We created this amazing Sweet Potato Cake with Marshmallow Buttercream Frosting. Sadly, though, it’s become increasingly difficult to find that muffin mix and I think it might actually be discontinued.

So when I was thinking about fall recipes and things I might be able to do with sweet potatoes, I thought I might give that old recipe a bit of a makeover and make it a bit more timeless. This new version of Sweet Potato Cake with Marshmallow Buttercream was born and, boy, is it an improvement.

In thinking about this, I decided that something akin to a carrot cake would make a great vehicle for some sweet potatoes. So I took Heather’s Great Aunt Frankie’s ridiculously amazing recipe for carrot cake and I gave it a sweet potato twist.

This perfectly dense, amazingly moist cake isn’t crazy sweet, so the marshmallow buttercream is the perfect sweet topping. I mean, sweet potatoes and marshmallows go together perfectly, right?

It has the perfect amount of sweet potato flavor without being overwhelming.

A few things to keep in mind:

You’ll need about 3 cups of shredded (or grated) sweet potatoes for this recipe. I just used a box grater to shred mine, but you can use a food processor as well. It took about 1 1/2 medium sweet potatoes to yield 3 cups. I like to bake this cake in a light-colored metal pan, but a ceramic or glass baking dish will work as well. Just keep in mind that using a different type of baking vessel may change the cook time. Dark-colored metal baking pans can often burn the outside of baked goods like this that require a lengthy time in the oven, so I might reduce the heat about 25 degrees to help prevent that from happening.

Yes, pecans can be a little pricey, but they’re worth it. Be sure to buy chopped pecans for this recipe. They’re cheaper to buy in pieces and it saves you the step of having to chop them. You can also use walnuts, if you wish.

I suppose that one really large potato might give you enough also.

If you love sweet potatoes and the dense texture and warm spice flavor of carrot cake, you’re going to love this. It might just be my new favorite dessert. Pumpkin spice ain’t got nothing on this one. Y’all enjoy.
