  • 0.5 cup vegetable oil

Equipment

  • 1 loaf pan

Method
 

Preheat and prep
  1. Preheat the oven to 350F and grease a 9x5 loaf pan.
  2. Whisk all-purpose flour, baking powder, baking soda, cinnamon, nutmeg, and salt together.
Mix the batter
  1. In a second bowl, whisk sweet potato puree, granulated sugar, brown sugar, vegetable oil, eggs, sour cream, and vanilla until smooth.
  2. Fold the dry mixture into the wet mixture until just combined, avoiding overmixing.
Add swirl and topping
  1. Pour half the batter into the prepared loaf pan.
  2. Drizzle the cinnamon swirl mixture over the batter.
  3. Pour the remaining batter into the pan and swirl with a knife for a marbled center.
  4. Sprinkle the cinnamon sugar topping over the top.
Bake
  1. Bake for 60-65 minutes at 350F, until a toothpick comes out clean.

Notes

Pro tip: roast and mash the sweet potato until very smooth so the loaf bakes up tender (no lumps). Store airtight at room temperature up to 3 days or refrigerate up to 5 days. Freeze slices in a freezer bag up to 2 months. For a dairy-light swap, use plain Greek yogurt in place of sour cream and proceed the same way.
