Provided are stiffened stringer panels with integrated plank structures. An example composite panel (100) comprises a skin member (510) having an inner surface (510-A), and a plank (400) on the inner surface. The plank comprises a set of layered laminate plies (420, 422, 424) and extends from a first side (402) to a second side (404). Each laminate ply of the set of layered laminate plies is sized to form a desired geometric profile for each of the first side and the second side. The composite panel further comprises a stringer (520) including a cap portion (521) that spans from the first side of the plank to the second side of the plank to form a first flange portion (524-A) and a second flange portion (524-B), respectively, on the inner surface of the skin member. Base segments of the cap portion conform to the desired geometric profile of respective first and second sides of the plank.
