Sweet Potato Pineapple Pound Cake

I *very excitedly* told my children that this Sweet Potato Pineapple Pound Cake was coming to the blog this week while we drove to school one morning.

Daughter: Is this a late April Fool’s Day joke?

Son: Why would you do that?

Well, Friends, THE JOKE IS ON THEM because this is, quite literally, one of my favorite pound cakes of all time. I ate this and slow danced by myself in the kitchen. This cake was hugging me from the insides and, as my father-in-law likes to say, tasted like more.

Great Scott I loved this cake! And yes, Friends, I can confirm that sweet potato and pineapple definitely go together. Even my son liked it, admitting that “it was good”.

About this Sweet Potato Pineapple Pound Cake

This cake uses crushed pineapple and sweet potato puree. The two together create an unbelievable texture for this particular cake, one that is dense and moist and…utterly perfect.

It’s sweet and subtly tangy from the pineapple, and also subtly sweet from the sweet potato. The pineapple glaze? Forget about it. It’s over-the-top incredible, and the perfect sweet addition at the end of the prep time.

The hardest part about making this cake is waiting until it’s completely cooled to consume it. But you can do this!

Ingredients in this Sweet Potato Pineapple Pound Cake

Stick with me here, Friends. The ingredients list looks much more daunting than it truly is!

All-Purpose Flour: All-purpose flour helps create the specific, special texture to this cake. The higher protein content helps to create the thick, dense-but-moist deliciousness that is key for this cake.

Kosher Salt: Salt helps to balance the sweet in baked goods. The tiny amount of salt in this recipe perfectly counterbalances the granulated sugar, as well as the sweetness in the pineapple and the sweet potato.

Cinnamon: The tiny kiss of cinnamon in this cake gives it just a hint of spice. It’s enough to make you feel warm and giddy, but not enough to overpower the wonderful flavors from the pineapple and sweet potato.

Ginger: Ginger adds a beautiful, warm element to this special cake. It’s the perfect compliment to the pineapple and sweet potato, and it helps bring the two special ingredients to their full potential. The ginger might *seem* like it’s a lot, but it’s truly the perfect amount!

Baking Soda: Pineapple is an acidic ingredient, making baking soda the appropriate leavening for this cake. Please don’t substitute baking powder!

Unsalted Butter: Butter is a star in this cake! It adds special flavor, and also the creaming process creates air pockets that allow this cake to rise into the special Sweet Potato Pineapple Pound Cake of your dreams! Use good butter for this cake, and make sure that it’s room temperature before you begin.

Eggs: The fatty yolks add flavor to this amazing to this cake, while the protein-rich egg whites assist with the texture and rise.

Granulated Sugar: Granulated sugar adds sweetness to this cake, but it also helps with caramelization! That gorgeous crust on the outside of your cake is largely due to the sugar in this recipe!

Vanilla Bean Pod: The mighty vanilla bean pod does so much in this cake. It truly plays above its weight and adds beautiful warmth and vanilla flavor. If you’re substituting vanilla extract, use a teaspoon. You won’t get the full vanilla flavor that I intended with this recipe, it it will still be over-the-top amazing.

Sweet Potato Puree: The sweet potato adds just a bit of sweetness to this cake, but, even more notably, it helps create the absolutely unctuous, delicious texture of this cake. I prefer to use homemade sweet potato puree (think: mashed sweet potatoes), but you can absolutely use canned sweet potato puree. Just don’t use sweet potato pie filling!

Crushed Pineapple: Use the juice and the pineapple for this cake! The sweet-tart flavor is truly an excellent addition. Once you have what you need for the cake, reserve some of the juice for the pineapple glaze as well.

Frequently Asked Questions About the Sweet Potato Pineapple Pound Cake

Why does the butter have to be room temperature before I start?

It’s exceptionally important for all of your cold ingredients to be room temperature before you begin. Room temperature ingredients create a smooth, cohesive batter that bakes evenly and creates the optimal texture in the finished cake. Cold ingredients (especially cold butter) can lead to chunky batter that’s…unpleasant.

What’s your favorite pan to use for these pound cakes?

I am a huge fan of Nordic Ware pans. They bake up beautifully every time. My Nordic Ware pans are all 10-cup pans, and they always fit all of the batter I put into them. I use them interchangeably for pound cakes and have never had a problem with overspill.

Why is this recipe written in metric?

The name of the game in baking is accuracy. Accuracy leads to consistency, which elevates your baking confidence to levels you never thought you could reach. How do I know? Because that’s exactly what happened to me!

Metric measurements are the smallest units of measurement, which means that they produce the most consistent and accurate results. So, I strongly recommend putting away the measuring cups (both liquid and dry!) and using a digital kitchen scale to measure most of your ingredients. This one recommendation alone will improve your baking exponentially!

Do I need to make my own sweet potato puree?

It’s my preference to make homemade sweet potato puree, but that does increase the amount of time that it takes to make the cake. To make my sweet potato puree, I peel, rinse and dice one large (or two medium) sweet potatoes. I add them to a pot with just enough water to cover the sweet potatoes, and then I boil them until they are soft (about 12 minutes after they start boiling). Once they are soft, I use a potato ricer to mash them to the perfect consistency.

Once the potatoes are the right consistency, set them aside and wait until they are cooled to room temperature to use them. If they are too warm, you will scramble the eggs in your cake batter and that is no good! You could also make the sweet potato puree a day ahead and place it in the refrigerator once it’s room temperature. To use, you would just take it out of the refrigerator at the same time as your other cold ingredients!

If you don’t want to do this process, trust me, I understand. You can absolutely use canned sweet potato puree and still make a fabulous cake. We just always have sweet potatoes in the house, so this hasn’t been a need for me.

Why a vanilla bean and not vanilla extract?

I tested this recipe with both vanilla extract and vanilla bean, and I found that the vanilla bean really shone through. The sweet potatoes and pineapples are heavy hitters in this case (both for taste and texture), and I was determined to have a vanilla addition that truly added the je ne sais quois that I was looking for with this cake. I found that special element when I added a vanilla bean.

You can achieve an element of vanilla with vanilla extract, but it won’t be nearly as special as it is with the vanilla bean. You can find an incredible price vanilla beans on Amazon!

Enjoy this recipe, my Friends! It is one for the record books and I cannot wait for you to try it!

Sweet Potato Pineapple Pound Cake

This incredible cake is pound cake perfection.  It’s sweet, luscious, slightly spiced goodness comes from a kiss of cinnamon and ginger, as well as the deliciousness from the pineapple and sweet potato!

  • Total Time: 5-7 hours
  • Yield: 18 servings 1x

Ingredients

Units Scale

For the Cake:

  • 384 g (3 c) all-purpose flour
  • 1 tsp kosher salt
  • 1/2 tsp cinnamon
  • 1/2 tsp ginger
  • 1/4 tsp baking soda
  • 227 g (1 c) unsalted butter, room temperature
  • 500 g (2.5 c) granulated sugar
  • 5 eggs, room temperature
  • 1/2 vanilla bean pod
  • 175 g (1/2 can) sweet potato puree, fresh or canned
  • 175 g (1/2 can) crushed pineapple, with juice

For the Vanilla Simple Syrup:

  • 84 g (1/3 c) water
  • 67 g (1/3 c) granulated sugar
  • 1/8 tsp fine sea salt
  • 1 tsp pure vanilla extract

For the Pineapple Glaze:

  • 240 g (2 c) confectioner’s sugar
  • 1/4 tsp fine sea salt
  • 1 tsp pure vanilla extract
  • 34 tbsp pineapple juice (strained from remaining crushed pineapple)

Instructions

  1. Preheat oven to a true 325°F.  An oven thermometer is essential for this step.  Many ovens run quite hot or cold, and it’s impossible to know unless you have an oven thermometer to gauge the true temperature in your oven!
  2. Sift the all-purpose flour, kosher salt, cinnamon, ginger, and baking soda into a medium bowl.  Set aside.
  3. In a large mixing bowl or the bowl of a stand mixer, mix the butter only until it is very smooth.  Add the sugar and cream the butter and sugar together until they are light and fluffy.  (Not sure how to cream butter and sugar?  Check out this post!)  Scrape the sides and bottom of the bowl as necessary.  Don’t shortcut this step!  It’s essential to great baked goods!
  4. Add eggs, one at a time, mixing each egg until it is fully incorporated before adding the next egg.
  5. Carefully split the vanilla bean pod lengthwise and scrape out the vanilla seeds.  Add them to the batter and mix thoroughly.
  6. Add half of the flour mixture and mix until nearly combined.
  7. Add all of the sweet potato puree and crushed pineapple and mix until nearly combined.
  8. Add the second half of the flour mixture and mix until nearly combined.
  9. Finish the batter by giving several turns with a stiff spatula, until you have a cohesive batter.  Make sure to thoroughly scrape the sides and bottom of the bowl during this step.
  10. Prep a 10- or 12-cup bundt pan and add the batter to the pan.  Bake for 65-75 minutes, or until an instant-read thermometer reads 212°F in the center.
  11. Remove the cake from the oven and allow to remain in the pan for ten minutes.  While the cake is in the pan, make the simple syrup.
  12. To make the simple syrup: Add water, granulated sugar, and salt to a small sauce pan.  Bring to a boil.  Turn off once all of the sugar is dissolved.  Remove from the heat and add the pure vanilla extract.
  13. Invert the cake on a cooling rack and brush immediately with simple syrup.  Allow to cool completely before adding the glaze.
  14. To make the glaze: add confectioner’s sugar, fine sea salt, pure vanilla extract, and 3 tbsp of pineapple juice to a medium bowl.  Still with a whisk until all of the confectioner’s sugar is moistened.  If necessary, add the rest of the pineapple juice in 1/2 tbsp increments.  The final glaze should have the consistency of thick honey.
  15. Using a spouted measuring cup, squeeze bottle, or spoon, place glaze atop your completely cooled cake.
  16. Enjoy!

  1. I think sweet potato needs more respect, so I’m glad I stumbled upon your pound cake recipe. Not only is it tasty, the crumb was perfectly tender and the buttery flavor divine!

  2. This cake was tender, buttery, perfectly sweet and so delicious! Using a real vanilla bean pod gave it wonderful flavor. I plan on making this again in a few weeks for a family cookout!

  3. The flavor of the sweet potatoes melded with the pineapple glaze beautifully. This cake was so moist and scrumptious all of my family approved.

  4. I have to admit I did not know how the pineapple and sweet potato flavors would work together but you have never steered me wrong with a pound cake so I tried it. This just works. WOW. Every slice was devoured in just a couple days and my family is on my back about making another. Thank you!

  5. The cake taste combo was great. The texture very nice. Mine was a little softer than typical dense pound cake and better I think . But WAY TO SWEET. I kept reading the recipe over and over because it’s 3 1/2 cups sugar in the cake then 2/3 cup of sugar combined for the syrup and glaze! Over 4 cups of sugar ! Also I thought that the syrup step could have been eliminated entirely to avoid the extra work and sugar. Next time I will bake with 3 cups sugar in batter, skip the syrup, thicken the glaze and and decorate with pineapple tidbits. Funny it almost tasted like it had coconut in it. So might decorate with coconut. I do think the recipe is a keeper! Thanks you !

    • Hi there! I really appreciate your comments and love that you found the texture to be nice. To be clear, the cake calls for 500 g (2.5 c) of granulated sugar for the cake, so I can understand why it would be too sweet with 3.5 cups. I’m glad you thought it was a keeper and hope you love it for years to come!
