Want to enjoy these scrumptious Peanut Butter Cookies but need a gluten-free option? Fear not! Substitute the all-purpose flour with your favorite gluten-free flour blend – one that's designed for a 1:1 replacement works wonders. Ensure that it contains xanthan gum, a key ingredient that mimics gluten's binding properties, keeping your cookies from crumbling apart. Also, double-check that your peanut butter and vanilla extract are labeled gluten-free, as these can sometimes contain hidden gluten.
