Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish.

In a large mixing bowl, cream together the unsalted butter and granulated sugar until light and fluffy.

Add the eggs, one at a time, mixing well after each addition until smooth.

Fold in the orange zest and orange juice until just combined.

Mix in the flour and salt gently until just combined.

Spread the batter evenly in the prepared baking dish and bake for 25-30 minutes.

In a separate bowl, beat the cream cheese and butter until smooth. Gradually mix in the powdered sugar and a splash of orange juice.

Let the brownies cool, then frost them generously with the cream cheese frosting.

Refrigerate the frosted brownies for at least 30 minutes before serving.
