To make these Potato Chip Cookies gluten free, replace the all-purpose flour with a certified gluten-free 1:1 baking flour blend. Also confirm that the potato chips, chocolate chips, vanilla extract, and baking soda are certified gluten free or free from hidden gluten-containing additives if needed for strict dietary requirements. If the gluten-free flour blend does not already contain xanthan gum, add it according to the manufacturer’s instructions for best texture.
