Step 1

Preheat oven to 180°C. Grease and line 2 baking trays with baking paper. Using an electric hand mixer, beat butter, vanilla, brown sugar, caster sugar and egg in a bowl until mixture is smooth and well combined.

Step 2

Sift flour over butter mixture and use a large metal spoon to stir in until just combined. Add cornflakes and choc bits. Mix well.

Step 3

Using 1/4 cup mixture per cookie, roll mixture into balls and place on prepared baking trays, making sure they are at least 6cm apart.

Step 4

Using damp fingertips, flatten cookies slightly. Bake for 8 minutes. Swap trays over in the oven and bake for a further 7 to 8 minutes or until light golden. Stand cookies on trays for 3 minutes. Transfer to a wire rack to cool completely. Serve.
