🛒 Ingredients

16 servings

16
  • 1 cup warm milk
  • 3 eggs
  • 4 tbsp melted margarine
  • 2 cups sugar
  • 1 cup unsweetened cocoa powder
  • 2 cups all-purpose flour
  • 1 tbsp baking powder
  • 1 cup sugar (frosting)
  • 3 tbsp cornstarch
  • 5 tbsp unsweetened cocoa powder (frosting)
  • 1 cup water
  • 3 tbsp margarine or butter (frosting)
  • 1 tsp vanilla extract

Directions

  1. 1

    Preheat oven to 350°F (180°C). Grease and flour a 9-inch round cake pan.

  2. 2

    Add warm milk, eggs, melted margarine, sugar, and cocoa powder to the blender. Blend for 2–3 minutes until completely smooth.

  3. 3

    Gradually add flour on low speed, then add baking powder and blend for an additional 15 seconds.

  4. 4

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

  5. 5

    For the frosting, combine sugar, cornstarch, cocoa, water, margarine, and vanilla in a saucepan over medium heat, stirring constantly until thickened to a glossy, spreadable consistency.

  6. 6

    Pour warm frosting over the cake and allow it to set for 10 minutes before slicing.

💡 Chef's Tip

Swap margarine for real butter for a richer flavor. Stir a handful of chocolate chips into the batter before baking for an extra indulgent treat.
