Step 1

Preheat oven to 200°C.  Line two large baking trays with oven proof baking paper. Mix butter and sugar together in a bowl until smooth and creamy.

Step 2

Add egg to butter mixture and mix again until smooth.

Step 3

Stir flours and chocolate into the butter mixture.  If the mixture seems a little dry, gently bring it together with clean hands.  The warmth from your hands will be just enough to combine the mixture.

Step 4

Roll tablespoons of mixture into balls, flatten slightly.  Place balls onto lined trays.  Bake for 15 minutes until slightly browned.  Cool on wire racks.
