Peanut Butter-chocolate Fudge Cupcakes


These dark, rich cupcakes topped with creamy, peanut buttery frosting will wow kids and grown-ups alike. The Italian meringue-based buttercream is soft and fluffy but holds up like a dream. You’ll need a candy thermometer to gauge the temperature of the sugar syrup used for the meringue.
