Sweet Potato Pound Cake with Brown Sugar Glaze

Sweet potato pound cake is the kind of cake that sits under a glass dome all week in a Southern kitchen and somehow disappears by Sunday. It has the dense, buttery crumb of a classic pound cake, the warm color of sweet potato pie, and a glossy brown sugar glaze that sets on top like candy.

It is my go-to when I need a holiday dessert that is easier than pie but still feels special. One pan, one bowl, and the house smells like Thanksgiving.

If you love a good pound cake, my brown sugar caramel pound cake and this old-fashioned Southern pound cake are family favorites too.

What Is Sweet Potato Pound Cake?

Sweet potato pound cake is a classic butter pound cake made with mashed sweet potato, brown sugar, and spices like cinnamon and nutmeg. The sweet potato adds moisture and a soft orange color without making the cake heavy.

Ingredient Tips

Bake or Microwave the Sweet Potatoes

Baked sweet potatoes are less watery than boiled ones.

Measure After Mashing

Pack the mash lightly into the cup for an accurate 2 cups.

Soft Butter

It should hold a fingerprint but not look greasy.

No Buttermilk?

Stir ½ tablespoon lemon juice into ½ cup milk and let it sit 5 minutes.

Fresh Spices

Old cinnamon tastes dusty; a fresh jar makes a big difference.

How to Make Sweet Potato Pound Cake

Step 1: Prep the Pan

Heat the oven to 325°F. Grease every crease of a 10 to 12-cup Bundt pan with soft butter or baking spray with flour, then dust with flour.

Step 2: Cream Butter and Sugars

Beat the butter, oil, granulated sugar, and brown sugar on medium for 4 to 5 minutes until light and fluffy.

Step 3: Add Eggs and Sweet Potato

Add the eggs one at a time, beating well after each. Beat in the mashed sweet potato and vanilla until smooth.

Step 4: Mix the Dry Ingredients

Whisk the flour, baking powder, baking soda, salt, cinnamon, nutmeg, and allspice in a separate bowl.

Step 5: Combine

On low speed, add the flour mixture in three parts, alternating with the buttermilk, beginning and ending with flour. Mix just until no streaks remain.

Step 6: Bake

Spread the batter into the pan and smooth the top. Bake 70 to 80 minutes, until a skewer in the thickest part comes out clean.

Step 7: Cool and Unmold

Cool in the pan for 15 minutes, then invert onto a rack and cool completely, about 1 hour.

Step 8: Glaze

Melt the butter and brown sugar in a saucepan, stir in the cream, and simmer 1 minute. Off the heat, whisk in the powdered sugar, vanilla, and salt. Let it thicken for 5 minutes, then spoon over the cake.

Expert Tips for Perfect Sweet Potato Pound Cake

Cream Long Enough

Five full minutes of creaming gives pound cake its fine, velvety crumb.

Do Not Open the Oven Early

Wait at least 60 minutes before checking or the cake may sink.

Tap Out Air Bubbles

Rap the filled pan on the counter twice before baking.

Glaze a Cool Cake

Warm cake absorbs the glaze instead of letting it drip.

Tent With Foil

If the top browns too fast, loosely cover it for the last 20 minutes.

Delicious Variations

Pecan Swirl

Layer half the batter, sprinkle cinnamon sugar and chopped pecans, then add the rest.

Cream Cheese Glaze

Use a simple cream cheese and powdered sugar glaze instead.

Loaf Pans

Divide between two 9×5 loaf pans and bake 55 to 65 minutes.

Maple Glaze

Swap the brown sugar in the glaze for maple syrup.

Bourbon Glaze

Add 1 tablespoon bourbon to the glaze.

What to Serve with Sweet Potato Pound Cake

Serve thick slices plain, warmed with a pat of butter, or with a scoop of vanilla or butter pecan ice cream.

For breakfast, toast a slice and pair it with coffee. It also sits nicely next to sweet potato muffins on a holiday brunch table.
