Step 1

Preheat oven to 180°C. Line 3 baking trays with baking paper.

Step 2

Using an electric mixer, beat butter, sugars and vanilla together until light and fluffy. Add eggs, 1 at a time, beating well after each addition.

Step 3

Sift flour and baking powder over butter mixture. Add nuts and chocolate. Stir with a large metal spoon until well combined.

Step 4

Drop heaped tablespoonfuls of mixture onto baking trays. Bake, 1 tray at a time, for 12 to 15 minutes or until light golden and firm to the touch (not crisp). Repeat with remaining trays. Stand on trays for 5 minutes. Transfer to a wire rack to cool.
