TIP: Try adding lemon curd to the frosting for an added zesty flavour.
Ingredients
Method
Grease a 20cm round cake pan. Line base and side with baking paper, extending paper 2cm above pan edge.
Beat butter, sugar, and vanilla in a small bowl of an electric mixer until light and fluffy. Beat in eggs, one at a time, until combined. Transfer to a large bowl.
Add the sifted self-raising flour, milk, and passionfruit in two batches. Stir until smooth. Spoon into the prepared pan. Smooth over top.
Cook in a moderately slow oven (160C) for about 50 minutes, or until a skewer inserted into the centre comes out clean. Remove from oven. Stand the cake in the pan for 15 minutes. Turn onto a wire rack to cool completely.
To make the frosting, combine icing sugar, butter, and milk in a small bowl. Beat with a wooden spoon until smooth.
Spread frosting over the top of the cake. Spoon over extra passionfruit before serving.
