180gmilk or dark chocolate chipsplus a few extra to press on top once baked
Instructions
Preheat your oven to 170°C/150°C fan.
Line your 8x8 inch baking pan with baking paper, parchment paper or foil. If using foil, spray it with some non-stick spray.Leave some overhang at the sides as this will make it easier to lift it out of the baking tray later, to cut into neat bars on a chopping board!
To a medium bowl add the plain flour, cornflour, bicarbonate of soda and salt. Whisk to combine and set aside.
To a large bowl add the light brown sugar, caster sugar and melted butter, and whisk until combined.
Next, add the egg yolks and vanilla extract to the large bowl and whisk until combined.
Add half of the dry ingredients to the large bowl and fold through until combined.
Repeat with the final half of dry ingredients.
Add the chocolate chips and fold through with a rubber spatula until evenly distributed throughout the cookie dough.
Pour the cookie dough into your lined 8x8 square baking pan. Spread the mixture into all corners and then press down with the rubber spatula to level out the top.
Bake for around 25-30 minutes. The cookie bars are done when a skewer inserted into the centre comes out clean.For slightly underbaked, soft centres as shown in my photos, my cookie bars took around 27 minutes to bake. If you'd prefer a more firm, baked centre bake for around 35-40 minutes.
Place the baking pan on a wire rack to cool. To slice into 16 bars, carefully lift out of the pan using the overhang of paper or foil and place onto a chopping board. Use a large sharp knife for neat cookie bar slices.
The cookie bars should keep well for around 3-4 days in an airtight container stored at room temperature.
