Use a whisk to thoroughly combine.In a separate bowl whisk together coconut milk, olive oil, 2 large eggs and orange juice until well blended.Stir the liquid ingredients into the dry ingredients and mix just until blended. Use a spatula to scrape the batter into prepared pan. Let the bread set, uncovered for about 30 minutes. While bread batter is resting, preheat oven to 350° F / 176° C. Prepare the glaze by whisking the powdered sugar and orange juice in a small bowl, until smooth. Set aside.Bake in preheated oven for 60-65 minutes, or until a toothpick inserted in the middle of the loaf comes out clean. Set the loaf pan on a cooling rack and use a wooden skewer or toothpick to poke about 24 holes in the top of loaf. Spoon the glaze over the top of the loaf and allow the loaf to cool in the pan for about 30 minutes.Remove loaf from pan.
