The lock made himself a Cardiff Blues hero last time out as his stunning injury-time try secured a thrilling comeback victory over Wasps in the Anglo-Welsh Cup.
However, Normandale has also impressed enough to be thrown into action in the GUINNESS PRO12 as he has featured twice off the bench.
And the 23-year-old, who is in his second season with the Blues, is eager to keep on learning his trade in the Welsh capital after agreeing a new two-year stay at BT Sport Cardiff Arms Park.
"I'm really pleased to have signed for another two years at Cardiff Blues," Normandale told the club's official website.
"I've learnt so much in my time here. Training has been intense and I feel now I've got used to that level and working with the boys has been brilliant.
"I know Hammer (Mark Hammett) likes my direct approach to the game and as long as I'm doing the hard graft I am happy.
"I feel so much more confident now and I want to put my strengths and skills into the right areas of the game."
Cardiff Blues director of rugby Mark Hammett added: "I've been impressed by Miles; his work ethic and attitude to get better and improve.
"He has all the physical attributes needed and has now got used to the environment here and what is expected from him.
"He made a big impression at Wasps and we were delighted for him. But his new contract is reward for what he has achieved all season and the very real potential we see in him.
"Miles will be Welsh qualified next year and we look forward to seeing how he develops over the rest of this season and the next two years."
