Prepare the Yeast Mixture – In a bowl, mix warm water, yeast, and sugar. Let sit for 5–10 minutes until foamy.
Mix the Batter – In a large bowl, combine flour, salt, Greek yogurt (if using), and the yeast mixture. Stir until a smooth batter forms.
Rest & Bake – Pour the batter into a greased cake pan and let it rest for 15 minutes. Preheat the oven to 375°F (190°C).
Bake Until Golden – Bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean.
Finish with Butter – Brush with melted butter or olive oil while warm for an extra-soft texture. Let cool slightly before serving.
