Preheat oven to 180°C. Line a large, flat baking tray with Mackies Nonstick Bakeliner.

Using an electric mixer, cream butter, sugar and vanilla in a bowl until pale and creamy. Add flour. Mix on low speed until just combined. Add milk. Stir until dough comes together. Using a wooden spoon, stir in cornflakes and choc bits.

Roll tablespoonfuls of mixture into balls. Place on Mackies Nonstick Bakeliner, allowing enough room for spreading. Flatten balls slightly with a spatula.

Bake cookies for 10 to 12 minutes or until light golden. Stand for 5 minutes. Transfer to a wire rack to cool completely. Repeat with remaining cookie mixture.
