  • 4 eggs - room temperature
  • ¾ cup of caster sugar
  • 125 grams of melted butter ½ cup
  • 1 teaspoon of vanilla extract
  • ¾ cup of plain flour - sifted
  • 2 cups of milk - lukewarm 500 mls
  • ¼ cup of icing sugar to decorate


  • Preheat your oven to 170 degrees and line a 20cm square cake tin with baking paper, making sure to leave plenty of paper hanging over the sides.
  • Separate your eggs and place the egg whites into a CLEAN and DRY bowl - this is very important and beat using an electric mixer until stiff peaks form. Set the egg whites aside until needed.
  • Place the egg yolks and caster sugar together in a large bowl and use an electric mixer to beat until they have combined and are light and frothy.
  • With the electric mixer still going on a low speed, gradually add the melted butter and vanilla extract before adding the sifted flour a few spoonfuls at a time.
  • Gradually add the lukewarm milk and continue to beat on a low- medium speed to combine all of the ingredients.
  • Add the egg whites to the bowl and gently fold together the mixture.
  • Pour the batter into your prepared cake tin and place into your preheated oven and cook for 35 minutes or until a golden crust has formed on top of your cake.


  • Your baking time WILL vary depending on the temperature of your ingredients.  Some people may find they need to cook their cakes for up to an hour.
  • I cook this cake in a 20cm square baking tin, you can use a different size tin but the cooking time will vary.
  • The mixture will look lumpy and you may be convinced that it won't work out - keep going as the end result is worth it!
