Making these delicious Chocolate Chip Cookie Dough Brownies gluten-free is surprisingly easy. It doesn't compromise their flavor. To start on your journey simply replace the all-purpose flour, in both the brownie and cookie dough layers with a high-quality gluten-free flour blend. Look for a blend that includes xanthan gum, an ingredient that mimics the binding properties of gluten ensuring that your brownies hold together with the tender texture as their gluten-containing counterparts. Additionally make sure to check the labels of your chocolate chips and other ingredients to ensure they are gluten-free as some chocolates may contain additives with gluten.
