2 cups all-purpose flour
1 ½ teaspoons baking powder
1 teaspoon baking soda
½ teaspoon salt
1 ½ teaspoons ground cinnamon
½ teaspoon ground nutmeg
1 cup granulated sugar
½ cup packed brown sugar
½ cup unsalted butter, softened
2 large eggs
1 teaspoon vanilla extract
1 cup buttermilk

For the Vanilla Glaze (Optional):

2–3 tablespoons milk or cream
½ teaspoon vanilla extract

👩‍🍳 Instructions and Preparation Method

Step 1: Prepare the Sweet Potatoes

Cook sweet potatoes until soft. Allow them to cool completely, then mash until smooth. The smoother the sweet potatoes, the softer and more delicate your cake texture will be.

Step 2: Prepare the Baking Pan

Preheat your oven to:

350°F (175°C)

Grease and lightly flour a 9×13-inch baking pan to prevent sticking.

Step 3: Make the Cinnamon Swirl

In a small bowl, combine:

Brown sugar
Ground cinnamon
Melted butter

Mix until it becomes a thick, sweet cinnamon paste. Set aside.

Step 4: Combine the Dry Ingredients

In a medium bowl, whisk together:

Flour
Baking powder
Baking soda
Salt
Cinnamon
Nutmeg

Mix well so the spices are evenly distributed throughout the cake.

Step 5: Cream the Butter and Sugars

In a large mixing bowl, beat:

Softened butter
Granulated sugar
Brown sugar

until light, fluffy, and creamy.

This step helps create a soft and airy cake texture.

Step 6: Add Eggs and Vanilla

Add eggs one at a time, mixing well after each addition.

Stir in vanilla extract until combined.

Step 7: Add the Sweet Potatoes

Mix the mashed sweet potatoes into the butter mixture until smooth.

The sweet potatoes add moisture, natural sweetness, and a beautiful golden color.

Step 8: Combine Batter

Add the dry ingredients and buttermilk alternately:

Add half of the flour mixture.
Add half of the buttermilk.
Mix gently.
Add remaining flour mixture.
Add remaining buttermilk.

Mix only until combined. Avoid overmixing, which can make the cake dense.

🍰 Cake Assembly Method

Pour half of the batter into the prepared pan.
Spread half of the cinnamon swirl mixture over the batter.
Add the remaining cake batter.
Spoon the remaining cinnamon mixture on top.
Use a knife or skewer to gently create beautiful cinnamon ribbons throughout the cake.

Do not over-swirl; you want pockets of cinnamon flavor throughout each slice.

🔥 Baking Method

Bake for:

40–45 minutes

The cake is ready when:

A toothpick inserted into the center comes out clean.
The top is golden.
The cake springs back lightly when touched.

Allow the cake to cool in the pan for about 15 minutes before transferring to a wire rack.

🍯 Making the Vanilla Glaze

In a bowl, whisk together:

Powdered sugar
Milk or cream
Vanilla extract

until smooth and creamy.

Drizzle over the cooled cake for an extra sweet finish.
