Chocolate-Sour Cream Frosting
Similar to dark chocolate frosting (page 302), this topping gets its intense color from the addition of semisweet chocolate. Sour cream and cream cheese impart tangy flavor and ultra-creamy consistency. This frosting would pair well with any chocolate cupcake, particularly devil’s food (page 34; also made with sour cream), as well as those made with banana, such as the roasted banana cupcakes on page 141.
