Overmixing: Overmixing the batter can develop the gluten in the flour, leading to a tough and dry texture. Mix just until the ingredients are combined. Overbaking: Check the bread a few minutes before the recommended baking time. Once a toothpick inserted into the center comes out with a few clinging crumbs, it's done. Incorrect oven temperature: Ensure your oven is preheated to the correct temperature before baking.
