Notes
Use high-quality bittersweet chocolate (60% cacao or more) for best flavor.Make sure butter is cold for the streusel to stay crumbly.Add 1 tsp instant espresso powder to the batter for deeper chocolate flavor.Yogurt can be used in place of sour cream with no loss in texture.Let cake cool completely before storing to preserve streusel texture.
