Old Fashioned Sweet Potato Loaf

You will want to try this recipe if you love the taste of sweet potatoes and chocolate! But be careful, because the recipe does call for walnuts, so if there is anyone you will serve it to who has nut allergy, either keep it aside or make this sweet potato loaf without adding nuts. And I also want to let you know that it is delicious served warm with some french vanilla ice cream – but I am sure that is not a surprise! 🙂


  • 2 cups of granulated sugar
  • 1/4 cup of coca powder
  • 1/4 cup of chopped walnuts
  • 1/2 cup of vegetable oil
  • 1 egg, beaten
  • 2 egg whites, beaten
  • 2 cups of mashed sweet potatoes
  • 2-1/2 cups of flour
  • 1 teaspoon of baking powder
  • 1 teaspoon of baking soda
  • 1/2 teaspoon of nutmeg
  • 1/2 teaspoon of cinnamon
  • 1/2 teaspoon of salt


  1. Preheat oven to 350F
  2. Combine 1/4 cup of sugar, cocoa and walnuts – set aside
  3. Beat together remaining sugar, oil, egg and egg whites until pale yellow
  4. Sift together flour, baking powder, baking soda, nutmeg, cinnamon and salt in a separate bowl
  5. Stir flour mixture into egg mixture just until combined
  6. Spoon half the batter into greased 9×5 inch loaf pan
  7. Sprinkle with half the cocoa mixture and swirl with a butter knife.
  8. Repeat layers, swirl again
  9. Finish with the remaining batter, swirl once more and smooth the top
  10. Bake for 1-1/2 hours or until toothpick inserted into the centre comes out clean
