• Preheat your oven to 350 degrees F
• Spray a 9 x 5" loaf with non-stick cooking spray and line two sides of the pan with Parchment paper. Leave some sticking out over the top to help lift the bread out later.
  
• Zest the orange using a fine grater or microplane. Gently grate around the orange, removing all of the dark part of the skin. Be careful not to grate the white part as it can be bitter. One large orange should yield about 3 teaspoons of zest. Set aside.
• Squeeze all of the juice from the orange into a bowl and set aside. I do this over a small mesh strainer to easily remove the seeds.
• In a medium size bowl, add the flour, sugar, baking powder, salt and two teaspoons of the zest. Stir to combine.
• 
• In a large bowl, combine the eggs, yogurt and vanilla and whisk until smooth.
• With the mixer on low speed, drizzle all of the melted coconut oil into the egg mixture. Beat until it's a pale yellow color, about one minute.
• Add the dry ingredients to the wet and mix until just combined, being careful not to overmix.
• 
• Pour the batter into your prepared pan and bake for 45 - 50 minutes or until a toothpick inserted in the center comes out clean (mine was perfect at 45). Do not overbake or you'll wind up with a dry bread.
• 
• Check the bread after about 35 minutes to see if it's getting too dark. If it is, lay a piece of foil over the top.
• At the 40-minute mark, check the bread to make sure it is completely cooked. An inserted knife will come out clean when it is done. If no, continue to bake, checking every 5 minutes, until done. Remove from the oven.
• Let the bread cool in the loaf pan for about 15 minutes before removing. Using the Parchment paper as "handles", lift the bread out of the pan and allow it to cool completely at room temperature.
• Serve with the glaze drizzled over the top or for dipping, if desired.

To make the glaze:

• Add the powdered sugar, four tablespoons of the orange juice and orange zest to a small bowl and whisk to combine. If the mixture is too thick, add the remaining orange juice, as needed.
• Microwave for 10 seconds, whisk and repeat two more times. This helps the sugars completely break down and the flavors to blend. Do not boil it. You’re just warming the glaze through. Put into a serving dish to serve with the bread.
