Total Time: 55-60 minutes
Servings: 12 generous slices

Ingredients You’ll Need

2 cups all-purpose flour
1.5 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1.5 teaspoons ground cinnamon
1.5 cups mashed sweet potatoes (cooked and cooled)
1 cup granulated sugar
1/2 cup brown sugar
1/2 cup vegetable oil
3 large eggs
1 teaspoon vanilla extract
1/2 cup buttermilk
1/4 cup brown sugar (for the cinnamon swirl)
1 teaspoon ground cinnamon (for the cinnamon swirl)
1 cup powdered sugar (for the glaze)
2-3 tablespoons milk (for the glaze)
1/2 teaspoon vanilla extract (for the glaze)

Step-by-Step Instructions

Preheat the oven: Set your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan to prevent sticking and ensure an easy release.
Mix dry ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and the 1.5 teaspoons of ground cinnamon until evenly combined.
Combine wet ingredients: In a large mixing bowl, blend the mashed sweet potatoes, granulated sugar, brown sugar, and vegetable oil until smooth and uniform in texture.
Add eggs and liquids: Add eggs one at a time into the wet mixture, mixing just until incorporated after each addition. Stir in the vanilla extract and buttermilk gently but thoroughly.
Combine mixtures: Gradually add the dry ingredients into the wet ingredients. Stir carefully just until everything is combined to avoid overmixing, which can make the cake dense.
Layer the batter and cinnamon swirl: Pour half the batter evenly into the prepared baking pan. In a small bowl, mix the 1/4 cup brown sugar and 1 teaspoon cinnamon for the swirl. Sprinkle this evenly over the batter. Pour the remaining batter on top and spread it gently to cover the swirl layer.
Create the swirl effect: Use a knife or skewer to lightly swirl the cinnamon mixture into the top layer of batter, creating beautiful marbling without blending it completely.
Bake: Place the pan in the oven and bake for 35 to 40 minutes. Test doneness by inserting a toothpick in the center; it should come out clean or with just a few moist crumbs.
Prepare the glaze: While the cake cools for 10-15 minutes, whisk together powdered sugar, milk, and vanilla extract for the glaze until smooth and slightly pourable.
Glaze and serve: Pour the glaze evenly over the slightly warm cake and spread gently. Allow the glaze to set for a few minutes before slicing and serving.

Pro Tips for Perfect Sweet Potato Honeybun Cake

Use properly cooked and cooled sweet potatoes: Boil or bake sweet potatoes until very tender, then let them cool completely before mashing for best texture and flavor integration.
Measure flour correctly: Spoon flour into your measuring cup and level with a knife to avoid dense cake due to too much flour.
Don’t overmix the batter: Combine ingredients until just incorporated to keep your cake light and moist.
Customize the cinnamon swirl intensity: Adjust the swirl ratio or cinnamon quantity to suit your taste preferences without overwhelming the sweet potato flavor.
Let the cake cool slightly before glazing: Pouring glaze over a warm but not hot cake allows it to soak in without melting away.

Variations and Substitutions

Healthier swaps: Substitute half of the all-purpose flour with whole wheat flour for added fiber and nutrients. Use applesauce instead of oil for a lower-fat version.
Dairy-free option: Replace buttermilk with a mix of almond milk and a teaspoon of lemon juice to create a similar tangy effect.
Nutty addition: Add 1/2 cup chopped walnuts or pecans to the batter or sprinkle on top before baking for texture and flavor.
Spice it up: Add 1/2 teaspoon ground nutmeg or ginger along with the cinnamon for a more complex spice profile.

Storage and Reheating Tips

Store your Sweet Potato Honeybun Cake in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to a week, ensuring it is well wrapped to maintain moisture.

To reheat, warm slices individually in the microwave for 15-20 seconds or until just warm. Avoid overheating to preserve texture and moisture. You can also warm slices in a low oven (about 300°F) covered with foil for 10 minutes.

If frozen, wrap the cake securely with plastic wrap and foil; thaw overnight in the refrigerator and warm gently before serving.

Frequently Asked Questions (FAQ)

Can I use canned sweet potatoes instead of fresh? Yes, but choose unsweetened canned sweet potatoes to control sweetness and texture. Drain any excess liquid before measuring.
What if I don’t have buttermilk? You can make a quick buttermilk substitute by adding 1/2 tablespoon lemon juice or white vinegar to 1/2 cup milk. Let it sit for 5 minutes before using.
Is this cake suitable for freezing? Absolutely! Wrap tightly and freeze up to 3 months. Thaw in the fridge overnight before reheating.
Can I make this cake vegan? To veganize, replace eggs with flax eggs (1 tablespoon flaxseed meal + 3 tablespoons water per egg) and use a plant-based milk and egg replacer instead of buttermilk and eggs.
How do I know when the cake is fully baked? Insert a toothpick into the center — it should come out clean or with a few moist crumbs, but no wet batter.
Can I add frosting instead of glaze? Yes! Cream cheese frosting pairs wonderfully with this cake for a richer finish.
