Preheat your oven to 350°F (175°C). Grease the loaf pan with cooking spray or butter.
In a mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and sugar until well combined.
In a separate bowl, mix the yogurt, egg, vegetable oil, and vanilla extract until smooth.
Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Do not overmix; a few lumps are fine.
Pour the batter into the prepared loaf pan and spread it evenly.
Bake in the preheated oven for 30 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
Remove from the oven and let it cool in the pan for 10 minutes. Then transfer the bread to a cooling rack to cool completely.
