- 1 teaspoon vanilla extract
- 3 cups all-purpose flour
- 1 teaspoon baking powder

How to Make Sweet Potato Pound Cake
1. Prepare the Sweet Potatoes
Cook the sweet potatoes until completely tender. Allow them to cool, remove the skins, and mash until smooth.
For the best texture, avoid leaving large chunks in the sweet potato mixture.
2. Prepare the Oven and Pan
Preheat your oven to 350°F (175°C).
Grease and flour a 10-inch Bundt pan thoroughly, making sure to coat all the grooves.
3. Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter and sugar together until light and fluffy.
This step helps incorporate air into the batter and contributes to a lighter pound cake.
4. Add the Eggs
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract.
5. Add the Sweet Potato
Mix the mashed sweet potatoes into the butter mixture until evenly incorporated.
The batter will become beautifully creamy and orange-golden.
6. Combine the Dry Ingredients
In another bowl, whisk together:
- Flour
- Baking powder
- Baking soda
- Salt
- Cinnamon
- Nutmeg
7. Finish the Batter
Add the dry ingredients to the sweet potato mixture gradually, alternating with the milk.
Begin and end with the dry ingredients. Mix only until everything is combined. Avoid overmixing.
8. Bake
Pour the batter into the prepared Bundt pan and smooth the top.
Bake for approximately 60–70 minutes, or until a toothpick inserted into the center comes out clean or with only a few moist crumbs.
Allow the cake to cool in the pan for about 10–15 minutes before carefully turning it onto a wire rack.
Make the Glaze
Whisk the powdered sugar, milk, and vanilla together until smooth.
If the glaze is too thick, add a little more milk. If it’s too thin, add a little more powdered sugar.
Drizzle over the completely cooled cake.
Tips for the Best Sweet Potato Pound Cake
Use room-temperature ingredients: Butter and eggs blend more easily and create a smoother batter.
Don’t overmix: Once the flour is incorporated, stop mixing. Overmixing can make the cake dense or tough.
Use smooth sweet potato: A smooth puree gives the cake a better texture.
Let it cool: Allow the cake to cool before glazing so the glaze doesn’t simply melt away.
Add extra warmth: For a richer fall flavor, you can add a pinch of ground cloves or allspice.
How to Store It
Keep the cake covered at room temperature for about 2–3 days. For longer storage, refrigerate it in an airtight container.
You can also freeze individual slices and thaw them when you’re ready for a homemade treat.
