Step 1

Preheat the oven to 160c (320f) and prep a 9-inch baking pan with parchment paper.

Step 2

Carefully separate the egg whites from the egg yolks and pour the egg whites to a stand mixer with a balloon attachment and gradually add the sugar over medium speed.

Step 3

Whip the mixture on high speed until the mixture is light and fluffy. You want stiff peaks in this mixture. Add the orange juice, egg yolks, orange zest, vanilla extract, kosher salt, vegetable oil, and mix over low speed until combined.

Step 4

Add the flour and baking powder and mix until there are no flour lumps visible.

Step 5

Pour the batter into a parchment paper lined 9 inch round baking pan and smooth it out using a spatula.

Step 6

Bake in a 160c (320f) preheated oven for about 40-45 minutes or until a toothpick inserted into the cake comes out clean.

Step 7

Top the cake with as much powder sugar as you would like, we like to top it with thin slices of orange and mint leaves.
