This Sweet Potato Pound Cake Recipe, made with silky smooth sweet potatoes, is perfect moist and tender with a spiced brown butter glaze.
Sweet potatoes were an extremely important food throughout my childhood. My mom made sweet potato pie for every Thanksgiving, and now that I’m an adult, I have fallen in love with the super tasty spud.
I eat a baked sweet potato for dessert on a regular, especially during the fall months. So, I’m no stranger to sweet potato dessert. This Sweet Potato Pound Cake recipe comes from my love of eating sweet potatoes as a dessert.
I didn’t grow up with this recipe, but this recipe is inspired by all the Southern desserts I was raised on (Caramel Cake, 7 Up Pound Cake, Cream Cheese Pound Cake). I developed this sweet potato pound cake recipe using the pound cake recipes I grew up on as an inspiration while creating something new: one of the best Southern desserts I’ve ever made!
Because pound cake was the first recipe I ever learned to bake, this sweet potato pound cake recipe is quite a special one for me. It brings together my fondness of pound cake and also my love and history with sweet potatoes, which were such a big part of my upbringing.
This Sweet Potato Cake Recipe has some incredible ingredients which give it such a fantastic taste:
- Both Granulated Sugar AND Brown Sugar
- Roasted Sweet Potato
- Cake Flour
I mostly use granulated sugar for baking cakes but for this cake, I wanted to add brown sugar too because it adds such a nice depth of flavor with the addition of molasses.
How to Roast A Sweet Potato
I personally love to prick, lightly oil then wrap a large sweet potato in foil and bake for about an hour at 400 degrees. You will want to test to make sure that the sweet potato is perfectly tender and soft before removing. If it is ready, then you are good to go!
How to Make Sweet Potato Pound Cake
- Preheat and Prep: Set your oven to 350 degrees and ready your loaf pan with non-stick spray.

- Vanilla and Mix: Pour in vanilla extract, beat until smooth.
