🛒 Ingredients

35 servings

35
  • 3 large eggs
  • 1½ cups (300 g) granulated sugar
  • 2 cups (250 g) all-purpose flour
  • 1½ cups (150 g) unsweetened cocoa powder
  • ½ cup (120 ml) vegetable oil
  • 1 tablespoon baking powder
  • ½ cup (120 ml) hot water
  • 1 can (14 oz / 395 g) sweetened condensed milk
  • 3 tablespoons chocolate drink powder
  • ½ cup (100 ml) heavy cream
  • Shredded coconut or chocolate sprinkles (optional)

Directions

  1. 1

    Preheat the oven to 350 °F (180 °C). Grease and flour a large baking pan.

  2. 2

    Add eggs, sugar, and oil to a blender. Blend on medium speed until the mixture turns pale and creamy, about 2 minutes.

  3. 3

    With the blender running, gradually pour in the hot water and blend until fully combined.

  4. 4

    In a separate bowl, whisk together the flour and cocoa powder. Add the dry mixture to the blender in three additions, blending briefly between each.

  5. 5

    Add the baking powder and pulse on the lowest setting just until incorporated — do not over-blend.

  6. 6

    Pour the batter into the prepared pan and bake for 40 minutes, or until a toothpick inserted in the center comes out clean.

  7. 7

    While the cake cools, make the topping: combine condensed milk and chocolate powder in a saucepan over low heat, stirring constantly until thickened to a fudgy consistency.

  8. 8

    Remove from heat, stir in the heavy cream, and mix until smooth and glossy.

  9. 9

    Pour the warm ganache over the cake and finish with shredded coconut or chocolate sprinkles if desired.

💡 Chef's Tip

Let the cake cool for 10 minutes before pouring the ganache so it sets beautifully on top. Leftovers keep well covered at room temperature for up to 3 days.
