Pre-heat the oven to 180°C/160°C Fan/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.
Press each ball flat and add either 5 mini marshmallows or 1 large marshmallow into the centre of the dough.
Pinch the dough upwards over the marshmallow/s to cover completely and roll back into a ball shape.
Place 5 balls on each of the lined baking trays and bake for 10 minutes until golden.
Remove the cookies from the oven and leave on a wire rack to cool completely.
