Mix the eggs, melted butter, vanilla, and orange juice.

Gradually add the sifted dry ingredients (flours and baking powder) while incorporating with the sugar.

Slowly add the milk in a thin stream, incorporating everything at the end.

Preheat the oven to 350°F (180°C), grease and flour a pan to pour in the mixture, bake for about 50 minutes, and check with a toothpick to ensure it's not undercooked or overcooked.

For the glaze, pour the orange juice into a small bowl or plate, then gradually add the powdered sugar until a soft paste forms. Adjust the consistency as desired to cover the bread.

You can garnish with orange slices or zest.
