Donegal had gone into the interval four points adrift of their opponents Warwickshire trailing by 0-12 to 0-08.
But they pulled back the deficit in the second period taking the coveted title 2-19 to 0-18.
It is a great prelude for Donegal as they also take on Fermanagh in the Ulster Senior Final tomorrow in Clones.
