Preheat your oven to 350°F (175°C). Grease a loaf pan.
In a large mixing bowl, combine flour, sugar, baking powder, and salt.
Add cranberries and orange zest to the dry ingredients and mix well.
In another bowl, combine orange juice, milk, beaten egg, and melted butter.
Pour the wet ingredients into the dry ingredients and stir until just combined.
Pour the batter into the prepared loaf pan and bake for 60 minutes or until a toothpick inserted into the center comes out clean.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
For the glaze, mix powdered sugar and orange juice until smooth. Drizzle over the cooled bread.
