In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until well combined.
Add the plain yogurt and warm water to the dry ingredients.
Using a wooden spoon or spatula, stir the mixture until a sticky dough forms and all the flour is incorporated.
Cover the bowl with plastic wrap or a clean kitchen towel and let the dough rest at room temperature for 1 hour.
After resting, lightly flour a clean surface and turn the dough out onto it.
Gently shape the dough into a round loaf by folding the edges toward the center without kneading.
Place the shaped dough onto a baking sheet lined with parchment paper.
Cover the dough loosely with a kitchen towel and let it rise for another 30 minutes.
Preheat the oven to 425°F (220°C).
Optionally, lightly dust the top of the dough with flour and score a shallow cross on top with a sharp knife.
Bake the bread in the preheated oven for 35 to 40 minutes, or until the crust is golden brown and the loaf sounds hollow when tapped on the bottom.
Remove the bread from the oven and transfer it to a wire rack to cool completely before slicing.
