Transforming our Toasted Coconut Shortbread into a gluten-free treat is not only possible but also a delightful journey! To embark on this adventure replace the all-purpose flour with your gluten-free flour blend. I suggest using a 1:1 flour that mimics the texture and baking qualities of traditional wheat flour. Keep in mind that each gluten-free flour blend has its combination of rice, potato, tapioca and sometimes even nut flours so the result may vary slightly each time. Which adds to the excitement! Pay attention to the dough consistency; if it feels too dry add a bit of butter. This straightforward adjustment guarantees that everyone can savor the buttery joy of our Toasted Coconut Shortbread nonetheless of their conditions.
