    Sweet Potato Cake

    Jump to Recipe - Print Recipe

    Sweet Potato Cake is dense and heavy but full of flavor for an extremely moist layer cake that's topped with luscious buttercream and candied pecans this decadent dessert is perfect for fall.

    I love this time of year and all the fruits and vegetables that are available. Now if only the weather would cool down to acceptable fall temperatures this year, all would be great! A girl can dream! I know you can get sweet potatoes all year long, but something just seems right about a sweet potato cake close to Thanksgiving.

    This cake is dense and heavy but full of flavor and extremely moist. I made my own sweet potato puree. It's super easy and worth the time. All I did was bake a few sweet potatoes, skin on. Then once they are cool from the oven, remove the skins, and put them in the food processor and puree the potato until it is smooth. You probably only need two medium sized potatoes for this recipe. I had no idea when I started and cooked six. You guessed it, there is more sweet potato recipes coming down the pipeline. We were eating sweet potato puree for days. It was a nice treat!

    You may be tempted to go to the store and buy a can of sweet potatoes. You could do this, but make sure it isn't the stuff with syrup. Sweet potatoes are already sweet, you don't need syrup. I ended up making the puree because I couldn't find a can of sweet potato puree, and all the cans of sweet potatoes had the syrup.

    How to Make Sweet Potato Layer Cake

    1. Prepare the cake batter and divide between three round cake pans.
    2. Bake until a toothpick inserted in the center comes out clean.
    3. Cool completely, then trim the tops until they are even.
    4. Make the buttercream and frost the cake layers.
    5. Sprinkle with candied pecans before cutting and serving.

    The buttercream is a light and fluffy one. The addition of the marshmallow creme made it a tiny bit sweet. I know you are thinking, how could you tell after 4 cups of powdered sugar... But you can. You could easily decorate this with regular buttercream and use no marshmallow creme if you would prefer. There was enough frosting to decorate the cake traditionally, but I'm still going with the naked cakes. I just like the look, and isn't this recipe really about the cake. So I try to give the cake its moment in the spotlight!

    The candied pecans are a great addition for texture. They are easy to make; just be careful with the boiling sugar. If you don't want to candy the pecans, you could just cut them up and sprinkle chopped pecans on top for decoration.

    The recipe makes three layers of cake, which is a perfect amount. We thought about turning this into a bundt cake and a few cupcakes but just liked the bites of frosting in the sweet potato layer cake.

    Give the recipe a try. I hope you like it as much as we do. If you are looking for other sweet potato cake recipes we whipped up a great bundt cake also for the holidays. Happy Holidays!

        I grew up with pumpkin and only in the last few years have I learned that there is more to a sweet potato than sugary syrup and marshmallows at thanksgiving. I'm loving them now.

      I like how you mention getting canned but without the syrup. That's my biggest frustration with buying canned goods, is all the extra sugar and it's also why I usually end up making it myself. This cake sounds amazing, I have never had sweet potato baked into a bakery item before.

        I know, it makes me crazy. So much processed stuff in food now a days. Something as simple as a sweet potato should not be packaged in a can with syrup. I will say, it's a pretty delicious cake if you like sweet potato. Definitely worth a try.

      A sweet potato cake is such a neat idea. I love sweet potatoes. And I agree that the fresh sweet potatoes are so much better than the canned ones. I loved canned sweet potatoes as a little kid, but can't stand them now.
