To make these cookies gluten-free. Simply swap out the all-purpose. And bread flours. For a high-quality gluten-free flour blend. Look for a mix. That includes xanthan gum. Or add it yourself. To mimic the chewiness you’d expect from regular flour. Ensure that your toffee bits are gluten-free. As some brands may use wheat products. With these easy substitutions. You’ll still get the same rich, flavorful cookies. Without any gluten.
