Preheat the oven to 180°C. Line two baking trays with non-stick baking paper. Place all dry ingredients (apart from the baking soda) into a bowl and stir to combine. Make a well in the centre.
Place butter and golden syrup in a saucepan to melt, or microwave in a bowl to melt. Dissolve baking soda in boiling water.
Add melted ingredients and dissolved baking soda to dry ingredients and mix to combine.
Roll spoonfuls into balls (if mixture too wet add an extra ¼ cup white flour) and press flat onto prepared baking trays, allowing space for biscuits to spread while cooking.
Bake for 10mins or until firm and golden brown. Remove to a wire rack to cool, and enjoy!
When cool store in an airtight container.
