Preheat Oven: Begin by preheating your oven to 350°F (175°C) and greasing a 9-inch round cake pan or lining it with parchment paper for easy removal.
Mix the Dry Ingredients: In a large bowl, whisk together the flour, baking powder, and salt. Set this mixture aside.
Combine Wet Ingredients: In another bowl, beat the eggs until frothy. Then add the granulated sugar, vegetable oil, yogurt, orange juice, and orange zest. Mix until everything is well combined.
Combine Mixtures: Gradually fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix—there's no need for toughness here!
Bake: Pour the batter into the prepared cake pan and smooth the top with a spatula. Bake for about 35-40 minutes, or until a toothpick inserted in the center comes out clean.
Cool: Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Serve: Once cooled, slice and serve with a dusting of powdered sugar or a dollop of Greek yogurt for an extra special touch!
