Step 1

Grease a 20cm (base measurement) round cake pan and line the base with baking paper. Use an electric mixer to beat the butter, sugar, lemon rind and cardamom until pale and creamy. Add eggs, 1 at a time, beating well after each addition. Stir in flour and yoghurt. Spoon into prepared pan. Smooth the surface.

Step 2

Preheat air fryer to 180°C. Place the pan in the basket of the air fryer. Bake for 35 mins or until a skewer inserted in the centre comes out clean. Set aside in pan for 5 mins before transferring to a wire rack to cool completely.

Step 3

To make the lemon icing, place the butter and icing sugar in a bowl. Stir in enough lemon juice to make a smooth paste.

Step 4

Place cake on a serving platter. Drizzle with the lemon icing and sprinkle with lemon zest to serve.
