Aircraft
Shortly after rotation; we noticed a smell that seemed to be electrical in nature. Shortly after the smell [was noticed] and a turn to assigned heading; we noticed a light colored smoke filling the cockpit. Before the turn that allowed sunlight into the cockpit; the smoke was not noticeable. We completed memory items and notified Tower that we would need to land. We were handed off to Departure who started to vector us toward [Runway] XXR for an immediate landing. Once leveling off we noticed that the smoke seemed to dissipate. After speaking with the Flight Attendant; we learned that there was smoke in the cabin as well. After learning this the Captain and I both agreed that we would land overweight. After landing and clearing the runway; Fire and Rescue advised that there was no visible smoke or fire coming from the aircraft. The Flight Attendant said that the passengers were not in need of assistance either. We elected to taxi back to the terminal.
EMB-145 First Officer reported smoke detected in cockpit and passenger cabin shortly after takeoff resulting in an uneventful return to departure airport.
