A rich and moist zucchini bread loaded with double chocolate chips and topped with a crunchy espresso crumble, balancing sweetness with a hint of bitterness.
Squeeze zucchini well to avoid soggy bread. Use Dutch-processed cocoa powder for smoother flavor. Fold batter gently to prevent toughness. Chill crumble mixture if kitchen is warm. Tent bread with foil if crumble browns too quickly. Use thawed and drained frozen zucchini if fresh is unavailable.
