• 125g butter, softened
  • 3/4 cup caster sugar
  • 1 teaspoon vanilla extract
  • 2 eggs
  • 1 1/2 cups plain flour
  • 1/3 cup Nestle baking cocoa
  • 1 teaspoon bicarbonate of soda
  • 1/4 teaspoon baking powder
  • 1/2 cup buttermilk

Vanilla frosting

  • 300g butter, softened
  • 2 1/4 cups icing sugar mixture, sifted
  • 2 teaspoons vanilla extract
  • Pink, green and blue food colouring


  • Step 1

Preheat oven to 180°C/160°C fan-forced. Line 4 large baking trays with baking paper. Using an electric mixer, beat butter, sugar and vanilla until light and fluffy. Add eggs, 1 at a time, beating well after each addition. Meanwhile, sift flour, cocoa, bicarbonate of soda and baking powder into a large bowl.

  • Step 2

Add half the flour mixture to butter mixture. Stir to combine. Add half the buttermilk. Stir to combine. Repeat with remaining flour mixture and buttermilk until just combined.

  • Step 3

Drop level tablespoons of mixture onto prepared trays, 5cm apart, allowing room for spreading. Bake, 1 tray at a time, for 8 to 10 minutes or until puffed and cooked through. Stand on trays for 2 minutes. Transfer to a wire rack to cool. Repeat with remaining trays.

  • Step 4

Make vanilla frosting: Using an electric mixer, beat butter, icing sugar and vanilla together until pale and fluffy. Divide frosting between 3 bowls. Using food colourings, tint 1 portion of frosting pink, 1 portion green and 1 portion blue. Sandwich level tablespoons of frosting between cakes to make 22 whoopie pies. Serve dusted with extra cocoa powder.
