4 large eggs
1 cup sour cream
¾ cup vegetable oil
1 teaspoon vanilla extract

For the Cinnamon Swirl

½ teaspoon vanilla extract (optional)

How to Make Sweet Potato Honey Bun Cake

Step 1: Prepare the Oven

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.

Step 2: Make the Cake Batter

In a large bowl, combine:

Yellow cake mix
Eggs
Sour cream
Vegetable oil
Vanilla extract

Mix until smooth, then fold in the mashed sweet potatoes until fully incorporated.

Step 3: Prepare the Cinnamon Filling

In a separate bowl, mix together:

Brown sugar
Cinnamon
Nutmeg
Chopped pecans

This mixture creates the signature honey bun swirl.

Step 4: Layer the Cake

Spread half of the batter into the prepared baking dish.

Sprinkle the cinnamon mixture evenly over the batter.

Top with the remaining batter.

Using a butter knife, gently swirl through the layers to create beautiful ribbons of cinnamon throughout the cake.

Step 5: Bake

Bake for 40–45 minutes, or until a toothpick inserted into the center comes out clean.

Allow the cake to cool for about 10 minutes.

Step 6: Add the Glaze

Whisk together powdered sugar, milk, and vanilla until smooth.

Drizzle generously over the warm cake so the glaze melts slightly into the top.

Serve warm or at room temperature.
