- 1 cup granulated sugar
- 1/2 cup packed brown sugar
- 1/2 cup vegetable oil
- 2 large eggs
- 1 cup buttermilk
- 2 tsp vanilla extract
- 2 1/2 cups all-purpose flour
- 1 tbsp baking powder

Instructions
- Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.
- Mix mashed sweet potatoes, granulated sugar, brown sugar, vegetable oil, eggs, buttermilk, and vanilla extract until smooth.
- Whisk together all-purpose flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger in another bowl.
- Stir the dry ingredients gradually into the sweet potato mixture until just combined.
- Combine the cinnamon swirl sugar (granulated sugar and ground cinnamon) in a small bowl.
- Pour half of your batter into the baking pan, then sprinkle half of the cinnamon swirl mixture over the top.
- Add the remaining batter and gently swirl with a knife to create marbling. Sprinkle the last of the cinnamon mixture on top.
- Bake for 35-40 minutes, until a toothpick inserted into the center comes out clean.
- Let the cake cool completely in the pan on a wire rack.
- Whisk powdered sugar, milk, and vanilla extract to create a smooth glaze; drizzle over the cooled cake.
