Chocolate Muffins

Don't these muffins look lovely? The recipe by Gluten Free Goddess can be found here. I made these changes:Used brown rice flour instead of quinoa flour, tapioca starch instead of potato starch, and guar gum instead of xanthan gum. I also decreased the nutmeg to 1/4 tsp., replaced the olive oil with canola oil, used 3/4 cup rice milk, replaced the Ener-G egg replacer and water with 3 tbsp.
