Preheat the oven to 180 °C. Grease and flour a 9 × 5-inch (23 × 13 cm) loaf pan or line it with parchment paper.
Sift 500 g plain 00 flour, 1 tablespoon granulated sugar, 1 tablespoon baking powder, and ½ teaspoon salt into a large bowl. Stir until evenly combined.
Add 450 ml milk and 2 tablespoons sunflower oil to a separate container. Mix until well blended.
Pour the wet ingredients into the dry ingredients. Stir just until combined; the batter should remain slightly lumpy.
Pour the batter into the prepared pan. Bake the no yeast bread for 45–50 minutes, until a toothpick inserted into the center comes out clean.
Cool the bread in the pan for 5–10 minutes. Remove it from the pan, then cool completely on a wire rack or serve warm.
Notes
Batter texture: Small lumps are expected; do not continue stirring simply to make the batter completely smooth.Pan size: The stated baking time is for a 9 × 5-inch (23 × 13 cm) loaf pan; do not assume another size will bake in the same time.Removing the loaf: Allow the 5–10-minute pan rest before lifting the bread out, and handle it carefully during the transfer to the rack.
