Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan or line with parchment paper.

In a large mixing bowl, cream the softened butter, granulated sugar, and brown sugar on medium speed for 2-3 minutes until light and fluffy.

Add the eggs one at a time, mixing well after each. Stir in orange juice, orange zest, and vanilla extract.

Whisk together flour, baking powder, and salt in a separate bowl. Gradually mix this into the wet ingredients until no dry pockets remain.

Pour the batter into the prepared pan and bake for 30-35 minutes until a toothpick comes out clean. Cool in the pan for 10 minutes before transferring to a wire rack.

For the glaze, mix powdered sugar and orange juice until smooth, adjusting as necessary.

Drizzle the glaze over the cooled cake and garnish with extra orange zest. Serve and enjoy!
