Chocolate Cupcakes with Peanut Butter Frosting

These chocolate cupcakes combine classic cocoa with a moist crumb and a rich peanut butter frosting. The use of buttermilk and a blend of melted butter and vegetable oil keeps the cupcakes tender and moist, while the peanut butter frosting offers a creamy, sweet contrast. Their texture makes them suitable for birthdays or gatherings where a balance of chocolate and peanut butter flavors is appreciated.

Description

Chocolate Cupcakes with Peanut Butter Frosting feature a batter enriched with both melted butter and vegetable oil, along with buttermilk to achieve a tender, moist texture. The cupcakes bake to a crumb that is moist yet sturdy, ideal for holding a thick peanut butter frosting. The frosting blends butter, creamy peanut butter, powdered sugar, and milk to achieve a smooth spreadable consistency. The combination balances the deep chocolate notes of the cupcakes with the savory sweetness of peanut butter, creating a classic flavor pairing.

The cupcakes are baked in standard muffin tins lined with paper liners, ensuring convenient portioning and easy removal. After baking, they cool before being generously topped with the peanut butter frosting, which can be garnished with chopped peanuts for texture. These cupcakes serve well as a dessert or for celebrations where rich chocolate treats are favored.

To prepare buttermilk, lemon juice is added to milk and allowed to thicken slightly. The recipe yields 24 cupcakes and enough frosting for about 24 servings or to cover a 9x13 inch cake. Store frosted cupcakes in an airtight container in the refrigerator. Unused frosting keeps for up to one week refrigerated. Unfrosted cupcakes freeze well for up to one month and should be thawed at room temperature prior to frosting.
