While the loaf is cooling, make the orange syrup in a small saucepan over medium heat. Stir together the orange juice and sugar until the sugar is completely dissolved. Once dissolved, continue to cook for 3 more minutes. Remove from the heat; set aside.
Use a toothpick to poke holes in the tops and sides of the warm loaf. Brush the top and sides of the loaf with the orange syrup. Let the syrup soak into the cake and brush again. Let the loaf cool completely.
To make the orange glaze, in a small bowl, whisk together the confectioners’ sugar and 2-3 tablespoons of the orange juice. The mixture should be thick but pourable. Add up to another tablespoon of orange juice if the mixture is too stiff. Pour the orange glaze over the top of each loaf and let it drip down the sides. Let the orange glaze harden, about 15 minutes, before serving.
