Ingredients

  • 250 g cooked sweet potato (equivalent to one medium sweet potato, orange flesh recommended)
  • 2 eggs
  • 120 ml vegetable oil
  • 80 g sugar
  • 150 g dark chocolate
  • 90 g flour
  • 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1 pinch salt
  • 1 tsp vanilla extract

Instructions

  1. 1Preheat the oven to 180°C (350°F). Grease a cake tin and line it with parchment paper.
  2. 2Cook the sweet potato, mash it into a puree, and let it cool.
  3. 3Melt the chocolate and let it cool slightly.
  4. 4In a large bowl, whisk the eggs with the oil, sugar, and vanilla.
  5. 5Stir in the sweet potato puree, then the melted chocolate.
  6. 6In another bowl, whisk together the flour, baking powder, baking soda, and salt.
  7. 7Add the dry ingredients to the wet ingredients and mix until you have a smooth batter. (Check for doneness with a toothpick: it should come out clean.)
  8. 8Pour the batter into the prepared tin and smooth the surface. Bake for approximately 30 to 35 minutes.
  9. 9Let the cake cool completely before removing it from the tin.

Tips

  • Use orange-fleshed sweet potatoes for more natural sweetness and creaminess.
  • This dessert is even better the next day after the flavors have developed.
  • Serve it with coconut whipped cream or fresh red berries.

Substitutions
