Preheat the oven to 350°F (175°C) and grease two loaf pans lined with parchment paper.

In a mixing bowl, cream together the softened butter and 2 cups of granulated sugar until light and fluffy.

Beat in the eggs one at a time, then add the orange zest and juice.

In another bowl, whisk together flour, baking powder, baking soda, and salt.

Gradually add the dry ingredients to the wet mixture, alternating with the yogurt and remaining orange juice until fully combined.

Pour batter evenly into prepared pans and bake for 45-55 minutes or until a toothpick comes out clean.

While baking, prepare glaze by combining powdered sugar with remaining orange juice; drizzle over cooled loaves.
