If you are a good skier, and fit, you could do it in a day. You would have to start at Dutchman flat and follow sno mo trails up, or there is a ski trail that goes to the right of sparks lake up to the plateau below Broken top. Then the fastest way is up the west ridge. You will be making your own trail to get to that point. there is no actual trail and sno mos aren't allowed back there. I would estimate 3-4 hrs one way depending on your ski ability. Also, its a lot faster on the way back.
