If you're a fan of the classic combination of peanut butter and chocolate, then you'll love this peanut butter chocolate lava cake. The cake is filled with a molten peanut butter center that oozes out when you cut into it. The peanut butter adds a rich, nutty flavor that perfectly complements the chocolate. Serve it with a dollop of whipped cream and a sprinkle of chopped peanuts for a dessert that is sure to impress.
