Preheat a grill to medium high. Combine the butter, hot sauce and 1/2 teaspoon salt in a small bowl; set aside.
Grill the corn, turning often, until lightly charred, about 10 minutes. Transfer to a plate. Meanwhile, rub the steak with the olive oil and season with salt and pepper. Grill 3 to 4 minutes per side for medium rare. Transfer to a cutting board and let rest 5 minutes; slice.
Spread the Buffalo butter on the corn and the steak. Top the steak with the blue cheese.
