A gas turbine engine ceramic matrix composite (CMC) component includes first and second outer layers of plies, and an intermediate layer of plies between the first and second outer layers of plies. The intermediate layer of plies is offset relative to the first and second outer layers of plies. The offset forms a protrusion on one side of the CMC component and a recess in an opposite side of the CMC component such that when two CMC components are assembled together, the protrusion of the one CMC component engages the recess of the other CMC component to form an edge seal between the CMC components.
