Preheat your oven to 350°F (175°C) and prepare an 8x8 baking dish by buttering it or lining it with parchment paper.

Zest and juice the fresh oranges, setting aside both components in separate bowls.

In a large mixing bowl, whisk the eggs, orange zest, and fresh orange juice until well combined.

Cream the softened unsalted butter and granulated sugar together until light and fluffy.

Gradually mix in the all-purpose flour and salt, then add the egg mixture until combined.

Pour the batter into the prepared baking dish and bake for 20-25 minutes.

While the bars cool, whisk together the powdered sugar, orange zest, and fresh orange juice for the glaze.

Once the bars have cooled, pour the orange glaze evenly over the top and chill for at least 30 minutes.
