Narrative:

We were filed and assigned FL350; we were experiencing light turbulence with occasional moderate; we called ATC to try and get a better ride at FL370 but the ride was worse so we requested a return to FL350; the ride had not changed from when we were there earlier. We were not painting anything significant on the radar and thought we would pass the weather with nothing more than we had already had. Approximately 5-10 min after we returned to FL350; we experienced a violent right bank to approximately 40-45 degrees (felt like a lot more) and altitude increased by approximately 1500 feet and a momentary shaker. The lowest airspeed I observed was around 210 KIAS and about mach .70; we were assigned FL370 so we climbed up and leveled off there; we still had some turbulence after that but not anything like we had in the moments prior. We continued to the destination. There were no injuries of flight attendants or passengers. ATC had advised us that the route at all altitudes was light to moderate at all altitudes. The dispatcher planned the route more east away from the worst of the line of thunder storms.
