Preheat the oven to 200C/180C Fan/Gas 6. Line 2/3 large baking sheets.
In a large bowl, combine the flour, baking powder, baking soda and chai spices and gently mix to combine. Add both sugars and mix again.
Make a well in the middle of the dry mix. Heat the golden syrup in the microwave for about 20 seconds - until runny. Add in the melted butter and runny golden syrup (see notes for alternatives). Stir to form a cookie dough.
Scoop heaped tablespoons of the dough and roll into about 8 balls. Place spread apart on the baking sheets - at least 2 inches of space apart.
Bake about 10-12 minutes, until golden! Let cool on a wire rack.
