Dark Chocolate Cupcakes with Creamy Peanut Butter Frosting
Rich, moist chocolate cupcakes topped with a silky peanut butter frosting create the perfect balance of deep cocoa flavor and nutty sweetness. The tender crumb comes from buttermilk and oil, while unsweetened cocoa powder delivers an intense chocolate taste that pairs beautifully with the creamy frosting. These cupcakes are ideal for birthday parties, school events, or whenever you crave a classic flavor combination that never goes out of style.

Don't overmix the batter once flour is added to prevent tough, dense cupcakes.
Test doneness with a toothpick in the center - it should come out with just a few moist crumbs.
