I picked one up for $10.
Even with the raised edges, there's plenty of thick, soft, chewy crumb layered in between the cheese and crispy crust. The crust was very thin over strips of cheese embedded in the pizza but remained cohesive and surprisingly crispy rather than soft and bready.
The stuffed cheese, while thoroughly melted, didn't stretch so much and, in contrast to the cheese on top, wasn't so flavorful. It was, however, fairly salty and very much like Pizza Hut's stuffed crust cheese.
Overall, Little Caesars' Stuffed Crust Deep Deep Dish Pizza was really enjoyable with a bevy of melted oozing cheese to go around. Everything turned out quite well although I might like it better with the same cheese inside that's on top, but there's still a nice contrast in both taste and texture between the two.
