You'll need the following items to make this recipe successfully.
- 12-cup bundt pan (I think this cake is only 10 cups but I like to make them in a 12 cup pan to be sure)
- electric mixer or stand mixer, optional - this can be made by hand
🥫 Storage
Southern sweet potato pound cake with rum will be fine at room temperature a little longer than most because of the rum. Cover with plastic wrap and it will stay moist and delicious for 5 days or so - but definitely keep an eye on it!
Freeze for longer storage. To freeze it you'll wrap in plastic wrap, then in aluminum foil - or place it in an airtight freezer container and freeze it for up to 3 months.
💭 Tips
Expert Tip: Use a no-stick baking or cooking spray for the bundt pan. It's easier to make sure that all the crevices are greased and that the finished pound cake will not stick.
- This cake doesn't need a glaze but it's pretty sprinkled with a little confectioner's sugar when it's served.
- The flavor develops overnight so try to hold off until the next day.
- I suggest baking the sweet potatoes right in their skins to cook them. This gives them the most intense flavor. Poke with a fork and bake at 425F for about 40 to 50 minutes or until fork-tender, soft, and done.
- Freeze this in slices with parchment paper between the slices for easy thawing and serving.
👩🍳 FAQs
Are sweet potatoes and yams the same?
Some people may try to tell you that there is no difference between sweet potatoes and yams but that's not true. They're not even related! They are very similar but sweet potatoes almost always have a more delicate flavor. Yams have more starch and tend to be dryer. You can substitute one for the other but they are not the same.
How can I tell when the cake is done?
You can stick a toothpick halfway between the center metal part and the edge and if it comes out with just a few crumbs clinging to it it's done. Also, an instant-read thermometer will read 210F when the pound cake is done.

📞 The last word
This one is for the sweet potato lover!
Unlike most of the rum cake recipes I have found, this one is from scratch start to finish. Well, you don't have to grow your own sweet potatoes or make your own rum— unless you want to, of course.
This is the best sweet potato pound cake I've ever tasted.
Pinkie swear.

Instructions
Sweet potatoes
Pierce the sweet potato skins with a fork.
Bake at 425°F for 40 minutes or until fork tender.
Let cool and remove skin.
Mash sweet potato with fork or pulse in a food processor until smooth. Don't add anything to it - you want plain sweet potato puree!
Cake
Preheat oven to 325 degrees F. Spray a 10 cup bundt pan with no-stick baking spray, nonstick cooking spray, or lightly grease and flour it.
Mix the flour, baking powder, ground cinnamon, and salt in a medium bowl.
Whisk the eggs, melted butter, vanilla, sugar, and brown sugar together in a large bowl or bowl of a stand mixer. If using a mixer just mix on medium speed for a minute or so.
Stir in the rum and mashed sweet potatoes until smooth.
Add in the flour mixture to the wet ingredients and stir until well blended. If using an electric mixer use low speed and just until all the dry ingredients are blended in - don't overmix.
Spoon cake batter into prepared bundt pan. Give it a quick drop on the counter to get the air bubbles out.
Bake about an hour or until a toothpick (or long wooden pick) inserted in the center comes out clean or it registers 210°F on an insta-read thermometer.
Remove from the oven and place on a cooling rack for 10 minutes.
Syrup
Combine the water, butter, sugar, and salt in a deep saucepan.
Cook over medium heat until the butter melts and the sugar dissolves.
Simmer it until it reduces just a little, about 2 more minutes.
Remove from the heat add the rum carefully.
To soak
Let the cake cool in the pan for 10 minutes.
Remove it from the pan completely.
Now, put the cake right back in the pan (this will help it not to stick).
Pour the syrup slowly over the warm cake, cover, and let stand for at least 24 hours.
Invert onto a cake plate or serving plate and serve. It's pretty dusted with powdered sugar just before serving.
Notes
Expert Tip: Use a no stick baking or cooking spray for the bundt pan. It's easier to make sure that all the crevices are greased and that the finished pound cake will not stick.
- The color of the cake will depend on the color of the sweet potato mixture. If it matters to you choose an orange variety of sweet potatoes.
- This cake doesn't need a glaze but it's pretty sprinkled with a little confectioner's sugar when it's served.
- I suggest baking the sweet potatoes right in their skins to cook them. This gives them the most intense flavor.
- Freeze this in slices with parchment paper inbetween the slices for easy thawing and serving.
- The flavor develops overnight so try to hold off until the next day.

Loved this so much! Delish!
Next time, I was wondering if you thought Pumpkin would substitute well for the sweet potatoes?Reply
Marye
You could but why not try this pumpkin bundt? https://www.restlesschipotle.com/browned-butter-pumpkin-bundt-cake/

Dear Marye,
May I serve the cake after 14 hours of soaking in the syrup? I don't see any more floating syrup? The butter did harden around the cake in the bundt pan. I have not flipped it over into the glass cake server. How do you recommend storing it?

Marye
I store at room temp.

Would you consider putting a glaze or icing on this cake?Reply
Marye Audet
Sure. A rum glaze would work well, or just dust with confectioner's sugar

Will this cake have a strong rum flavor like cake dipped in alcohol? I’m only asking because my husband and I don’t drink but we know that cooking or baking alcohol gives foods it a different type of flavor? Thanks! 🙂

Marye Audet
yes. you can just leave it off the finished cake and substitute apple juice in the batter.

I made this recipe exactly as written using regular sweet potatoes. I am an experienced home-baker and this is one of the best cakes I have ever made. The cake is very moist and the flavors are on point for a fall dessert. Thank you!Reply

Joan do you cook the sweet potatoes? Bake them or boil them? Maybe it doesn't matter??

Marye Audet
I bake mine - I think it gives them better flavor.

This sounds great, and looks super moist. What is the difference between a regular sweet potato and an heirloom?
Reply
Marye Audet
Heirlooms are varieties that have bee around for a long time. The flavors are usually very unique
