An incredibly moist and fudgy chocolate cake where sweet potato replaces butter for a creamy texture without the vegetable taste. A delicious and healthier surprise.

Ingredients

Serves : 4 servings

  • 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

Step 1

Preheat the oven to 180°C (350°F). Grease a cake tin and line it with parchment paper.

Step 2

Cook the sweet potato, mash it into a puree, and let it cool.

Step 3

Melt the chocolate and let it cool slightly.

Step 4

In a large bowl, whisk the eggs with the oil, sugar, and vanilla.

Step 5

Stir in the sweet potato puree, then the melted chocolate.

Step 6

In another bowl, whisk together the flour, baking powder, baking soda, and salt.

Step 7

Add 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.)

Step 8

Pour the batter into the prepared tin and smooth the surface. Bake for approximately 30 to 35 minutes.

Step 9

Let 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

  • Butter → Sweet potato — Used as a butter substitute for a fudgy texture.
