Pre-heat the oven to 160°C fan/180°C/Gas mark 4 and line 2 baking trays with baking parchment.
Place the Fate Low Protein All-Purpose Mix, baking powder and Vitabite chunks into a mixing bowl and stir to combine.
With your fingertips rub in the butter, until the mixture resembles fine breadcrumbs.
Add the caster sugar and dark brown sugar and mix well.
Pour in the syrup and stir to form a soft dough (add a little water if there are still crumbs in the bowl).
Divide the dough into 10 equally sized pieces and roll into balls.
Place each ball on the lined baking trays and press down lightly to flatten.
Bake for 10 minutes until golden.
Remove the cookies from the oven and leave on a wire rack to cool completely.
