A quick and easy one-bowl chocolate zucchini bread with espresso and walnuts that is moist, rich, and perfect for last-minute baking emergencies or casual treats.
Do not overmix the batter to avoid tough bread. Grate zucchini finely for even texture. Toast walnuts for extra flavor. Tent with foil if browning too fast. Brush top with melted butter for a glossy finish. Espresso powder enhances chocolate flavor without coffee taste; substitute with instant coffee if needed (reduce oil slightly).
