Sift in the flour and fold into the mixture with the bicarbonate of soda and salt
Gently mix in the chocolate chunks
Bring together into a dough
Shape the dough with your hands into fat balls and place onto a parchment lined baking tray leaving a large space between each one, as they can spread quite a bit. Do not flatten these as you want them squidgy. If you flatten them you'll end up with gigantic crispy biscuits.
Bake for 8-10 minutes
Leave for 2 minutes to set a little and then carefully move the cookies onto a wire rack to cool
