- cooking spray
- 1 sweet potato

- Preheat oven to 350 degrees F (175 degrees C). Spray a 9×5-inch loaf pan with cooking spray.
- Place sweet potato on a microwave-safe plate and pierce skin 5 or 6 times. Cook in the microwave, rotating halfway through, until tender, 5 to 8 minutes. Cool until easily handled, about 5 minutes. Peel and mash in a small bowl.

- Pour applesauce mixture over flour mixture; stir to combine. Fold in walnuts. Pour into the prepared loaf pan.
