Back in the day, Karson's was one of Baltimore's best-known restaurants. As former Baltimore Sun restaurant critic Elizabeth Large said, "Customers lined up around the block for executive chef George Karson's Maryland seafood and steaks." But after Karson's father, a co-owner, died in the mid-1980s, the restaurant's popularity began to fade. Although Karson tried to revive the place in the late 1990s, it did not survive. Unfortunately, I was unable to locate anyone who had the recipe for the exact peanut butter cake that Karwacki was in search of.
