Create your own dainty Madeleine cookies with a peanut butter flair. These small finger cookies are soft and light in both texture and flavor, which makes them easily paired with any ice cream or dipping sauce. Adding peanut butter not only gives the dough a nutty sweet taste, but also keeps the center of the baked dough smooth. Line a tray with these cute cookies for a sophisticated display of scrumptious cookies and watch them disappear.
