This is recipe is the closest I could get to the traditional Nestle's recipe, but have it be gluten free and nut free. Unfortunately, that means I couldn't use Nestle chocolate chips anymore. The good news is that there are two awesome, high-quality brands that are nut free. They are the Ghiridelli brand and Guittard brand. The Xanthan gum helps the cookies not crumble, along with the Flaxseed meal which also adds some nice nutty flavor to an otherwise bland batter. You can add a little more Flaxseed Meal for more flavor, but you would have to add a little more moisture as well (1 tbsp water), since it soaks it up. For most of my baking recipes I've found that adding an extra teaspoon of vanilla extract helps with the flavor as well, as the first teaspoon seems to disappear in a gluten free recipe.
