Preheat the oven to 350°F (175°C). Grease your baking pan of choice and optionally line with parchment paper.
In a medium sized bowl, whisk together the flour, salt, and baking power.
In a large bowl, whisk together the yogurt, eggs, sugar, vanilla, and lemon zest.
Slowly whisk the dry ingredients into the wet ones. Stop when everything is fully combined and the batter is smooth.
Slowly stir in the oil, stopping as soon as everything is mixed together.
Pour the batter into the prepared pan, and place in the oven on the center rack for 30-45 minutes. Make sure to check with a toothpick starting at 30 minutes and remove from the oven as soon as the toothpick comes out clean.
Allow the cake to cool for 10 minutes, and then remove it from the pan. Enjoy!
