Ingredients

Brownie ingredients

  • 250 g butter or margarine
  • ½ cup cocoa powder
  • 2 cups sugar
  • 4 large eggs, lightly beaten
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1½ cups flour, sifted
  • 2 teaspoons vanilla essence
  • 20–24 white marshmallows, each cut into quarters

Chocolate topping

  • 2½ tablespoons butter
  • 2 tablespoons cocoa powder
  • 3 tablespoons milk
  • 2 cups icing sugar, sifted

 


Instructions

  1. Place the butter in a large microwave-safe mixing bowl. Microwave on high for 1–2 minutes, or until melted.
  2. Stir in the cocoa powder and sugar. Add the lightly beaten eggs and mix until well combined.
  3. Sift together the flour, baking powder and salt, then gently fold into the chocolate mixture. Stir in the vanilla essence.
  4. Pour the batter into a lightly greased 20 × 29 cm microwave-safe dish. Microwave on medium-high for approximately 10–12 minutes, or until the brownie begins to pull away from the sides.
  5. While still warm, arrange the quartered marshmallows evenly over the top. Cover with cling wrap and leave for about 20 minutes, allowing the marshmallows to soften and melt. Remove the cling wrap and leave to cool.
  6. For the topping, place the butter, cocoa powder and milk in a microwave-safe bowl. Microwave on high for approximately 30 seconds, then stir until smooth.
  7. Add the sifted icing sugar and beat until smooth and spreadable.
  8. Spread over the marshmallow layer. Allow the brownie and icing to cool and set completely before cutting into squares.
