Step 1

Preheat oven to 180°C. Line two oven trays with baking paper.

Step 2

Use an electric mixer to beat the butter and sugar together until pale and creamy. Add the treacle, vanilla and milk and beat until well combined.

Step 3

Add the flour and bicarbonate of soda and stir with a wooden spoon until combined. Add the white choc bits and macadamias and stir to combine.

Step 4

Roll a heaped tablespoonful of mixture into a ball and place on a lined tray. Use the palm of your hand to gently press the mixture. Repeat with remaining mixture.

Step 5

Bake in preheated oven, swapping trays halfway through cooking, for 15 minutes or until golden brown and crisp. Remove from oven. Allow cookies to cool on the trays.
