Preheat oven to 170°C.
Place the butter and golden syrup into a small saucepan over low heat, stirring ocassionally until butter is melted. Set aside to cool slightly.
While the butter is melting; place the flour, cornflakes (slightly crush with hands), quinoa flakes and sugars into a bowl and mix well.
Combine 1 & 1/2 tbsp boiling water with the bicarb soda in a small bowl or measuring cup. Add to the dry mixture along with the butter mixture. Stir until well combined.
Roll small balls of the mixture and place onto lined baking trays, allow space for spreading.
Bake for 15 minutes. Separate biscuits if necessary before leaving them to cool. Biscuits will harden as they cool.
