• Preheat oven to 350 F. Grease 1 regular/large loaf pan, or line with parchment paper.
• In a large bowl, whisk together flours, baking powder, xanthan gum, baking soda, and salt. Set aside.
• In a separate bowl - a small or medium bowl - whisk together sugar, yogurt, orange juice, vegetable oil, eggs, vanilla, and orange zest until smooth and well combined.
• Add the wet ingredients mixture to the mixing bowl of dry ingredients, along with the cranberries and nuts, if using. Use a wooden spoon or rubber spatula to stir just until combined.
• Pour batter into prepared pan.
• Bake for about 1 hour, or until crust is a rich golden brown, and knife inserted into middle of loaf comes out clean.
• Once fully cooked, remove from oven, and let the bread cool on a cooling rack while you make the glaze:

Orange Glaze

• Whisk together the orange juice and salt.
• Add about the powdered sugar, a little at a time, whisking until smooth. You want it VERY thick, but you can add extra orange juice if you need.
• Drizzle glaze over the warm loaf, allow to cool for at least 15-20 minutes before cutting - if you’ve got that kind of patience!
• You can use a wire rack to help it cool faster, if you like.
