Preheat the oven to 180°C and grease and line a 20 x 30cm baking tray.
Mix together all the dry ingredients except the sugar and bicarb.
In a medium saucepan, melt the butter and add the sugar and syrup. Stir until the sugar is dissolved and the mixture starts bubbling.
Dissolve the bicarb in the milk.
Mix the butter mixture and the milk mixture into the dry ingredients.
Spoon into the prepared baking tray and flatten.
Bake for 25 to 30 minutes. If the cookies brown too quickly, turn the oven down to 160°C.
Once baked, cut the cookies into squares and let cool down before you transfer them to an airtight container.½
