Preheat your oven to 350°F (175°C).

Grease your 9x5 inch loaf pan with butter or cooking spray.

In a mixing bowl, whisk together the flour, baking powder, and salt.

In another bowl, beat the softened butter and sugar together until light and fluffy.

Add the eggs, vanilla extract, orange zest, and fresh orange juice to the butter mixture and mix until well combined.

Gradually add the dry ingredients to the wet mixture, stirring until just combined.

Pour the batter into the prepared loaf pan.

Bake in the preheated oven for 60 minutes or until a toothpick inserted in the center comes out clean.

Let it cool in the pan for about 10 minutes before transferring it to a cooling rack.
