How to Make Sweet Potato Honeybun Cake
1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan to prevent sticking.
2: Combine Wet Ingredients
In a large mixing bowl, combine the mashed sweet potatoes, granulated sugar, brown sugar, vegetable oil, eggs, buttermilk, and vanilla extract. Stir until smooth and well-blended.
3: Mix Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger. Sifting helps aerate the flour, ensuring a light and fluffy cake.
4: Create the Batter
Gradually add the dry ingredients to the wet ingredients, mixing gently until combined. Avoid overmixing to keep the cake soft and moist.
5: Add the Cinnamon Swirl
In a small bowl, mix the granulated sugar and cinnamon for the swirl.
- Pour half of the cake batter into the prepared baking pan.
- Sprinkle half of the cinnamon swirl mixture evenly over the batter.
- Add the remaining batter, then use a knife to swirl the layers gently to create a marbled effect.
- Top with the remaining cinnamon sugar mixture.
6: Bake to Perfection
Bake the cake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely in the pan on a wire rack.
7: Prepare the Glaze
In a small bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth. Drizzle the glaze over the cooled cake for a sweet, glossy finish.
Serving and Storage Tips
- Serving: This dessert cake is best served at room temperature or slightly warmed. Pair it with a cup of coffee or tea for a cozy treat.
- Storage: Store the cake in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days.
- Freezing: Wrap individual slices in plastic wrap, place them in a freezer-safe bag, and freeze for up to 3 months. Thaw at room temperature before serving.
Variations and Substitutions
- Add Honey: For extra moisture and sweetness, mix 1 tablespoon of honey into the batter.
- More Cinnamon: If you love a bold cinnamon flavor, increase the cinnamon in the swirl to 1 1/2 tablespoons.
- Gluten-Free Option: Substitute the all-purpose flour with a gluten-free flour blend.
Expert Tips for the Best Sweet Potato Honeybun Cake
