Luton striker Carlton Morris rued their slow start after defeat at home to Manchester United.
Hojlund struck twice for the visitors, with Morris pulling a goal back in the first-half.
He later said: "It's hard not to be disappointed but we're in a business where you can't get too down or two up. We'll look at what we've done for us to be goals down.
"I have so much faith in the boys that I never think we're out of the game. We've shown we're capable this season but it wasn't to be.
"All the stuff we've worked on in the week was working. We had the majority of the ball against Man United. It shows how far we've come from the start of the season.
"You can say we're performing well but it's a results business. We need to perform better in both boxes and that's something we're working hard on."
