Preheat your oven to 350 degrees Fahrenheit.
Grease your cake pan with butter nicely.
Line the bottom with parchment paper carefully.
This prevents sticking when cake is done.
Set the pan aside for now.
Take a bowl and add flour first.
Add baking powder and baking soda next.
Put in the salt as well.
Whisk everything together until well combined.
Set this bowl aside for later use.
Grab another large mixing bowl now.
Crack eggs into it and beat well.
Add sugar and mix until fluffy.
Pour in the oil and yogurt next.
Add vanilla extract for extra flavor.
Zest both oranges into the mixture.
Squeeze the juice from oranges and add.
Mix everything until smooth and creamy.
Add dry ingredients to wet ingredients slowly.
Mix gently until just combined properly.
Do not overmix the batter at all.
Overmixing makes the cake tough and dense.
The batter should look smooth now.
Pour batter into your prepared pan carefully.
Smooth the top with a spatula gently.
Place pan in the preheated oven immediately.
Bake for 40 to 45 minutes total.
Check with a toothpick in the center.
It should come out clean when done.
Remove cake from oven when ready.
Let it cool for 10 minutes first.
Then remove from pan to cooling rack.
Let it cool completely before cutting.
Dust with powdered sugar if you like.
