Step 1

Grease a 20cm round cake pan. Line base with baking paper.

Step 2

Use electric beaters to beat the butter, sugar, flour, eggs, lemon rind and juice for 3-4 minutes or until pale and creamy. Spoon batter into prepared pan. Smooth surface.

Step 3

Place the pan in the basket of the air fryer. Set the air fryer to 160C. Bake for 25 mins or until a skewer inserted in the centre comes out clean (see tip). Set aside for 5 minutes before transferring to a wire rack to cool.

Step 4

Serve the cake warm or at room temperature.
