An Australian representative at U20 and U23 level, Danning's youth and speed make him an ideal addition to Head Coach Ange Postecoglou's championship-winning squad.
"Kofi is someone we highlighted at the end of last year and I think he'll fit into our system well so it's pleasing that he's finally signed for us for a couple of years," Postecoglou said.
"We've got a lot of work to do with him but he fits into our style of game really well and I think he'll develop into a real attacking weapon for us over the next twelve months.
"We're quite confident in the style of player he is and the type of person he is so I'm sure he'll do really well for us."
The former Sydney FC player was ecstatic to be in the Queensland capital, delighted to have the opportunity to learn and develop as a footballer under the guidance of Postecoglou and his coaching staff.
"I'm so excited to be here and to start a new season and a whole new experience," Danning said.
"I've spoken to Ange and he sees me developing here and sees me improving my game and sees me getting opportunities, which is good for me because that's all I want.
"I want to prove myself to everyone, that's why I've come to Brisbane - to do the best I can and to make people proud."
