280g (2 cups) plain flour
1/2 teaspoon baking powder
40g (1/3 cup) cocoa
250g unsalted butter, softened at room temperature, diced
185g (3/4 cup) caster sugar
150g brown sugar
2 large free range eggs, beaten
200g dark chocolate chips
Preheat the oven to 180C (Fan forced 160C). Line two baking trays with baking paper. Sift the flour, baking powder, cocoa and a pinch of salt into a bowl.
Beat the butter and sugars with hand-held electric beaters until pale and fluffy. Beat in the eggs, a little at a time, alternating with a little of the flour mixture until combined. Fold in the remaining flour mixture, then stir in the chocolate chips.
Place tablespoons of the mixture onto the trays, leaving room for spreading (about 12 per tray). Bake for 8 minutes then remove and leave to cool on the tray for 2 minutes. You may need to bake a third tray if any mixture remains. Transfer to wire racks to cool completely. Store in an airtight container for up to 5 days. Makes about 30
