Instructions

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C).
Grease and flour a 9×13-inch baking pan or line it with parchment paper.

Step 2: Make the Cake Batter

In a large mixing bowl, whisk together the mashed sweet potatoes, sugar, oil, milk, eggs, and vanilla until smooth.
In another bowl, sift together the flour, baking powder, baking soda, salt, and cinnamon.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.

Step 3: Create the Cinnamon Swirl

In a small bowl, mix the brown sugar, cinnamon, and melted butter until combined.
Pour the cake batter into the prepared pan and smooth the top.
Drizzle the cinnamon swirl mixture over the batter. Use a toothpick or skewer to gently swirl it into the batter for a marbled effect.

Step 4: Bake the Cake

Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10 minutes, then transfer it to a cooling rack.

Step 5: Add the Glaze

In a small bowl, whisk together the powdered sugar, milk, and vanilla until smooth.
Drizzle the glaze over the cooled cake for a sweet finish.

Notes

Choose the Right Sweet Potatoes: Use orange-fleshed sweet potatoes for their natural sweetness and vibrant color.
Make Ahead: Bake the cake a day ahead and glaze it just before serving for a perfectly moist texture.
Customize the Swirl: Add a pinch of nutmeg or cardamom to the cinnamon mixture for extra depth of flavor.
