To prepare gluten-free Nutella Scones, substitute the all-purpose flour with a high-quality 1:1 gluten-free flour blend that includes xanthan gum for structure. Ensure all other ingredients, particularly the Nutella and baking powder, are certified gluten-free. Handle the dough gently, as gluten-free doughs can be slightly more delicate. Resting the dough briefly before baking may improve texture and consistency.
