All I do is make a normal breakbeat, like so. Make sure your samples are good, and well-mastered. The hats in particular should be snappy, and not too heavy on high frequencies.
Then, what I personally do is get a premade drum loop (the type that has loads of hats and conga fills and whatnot), EQ out a tonne of frequencies, so the loop won't clash with the breakbeat I made, turn the volume down so it's a bit more subtle, and layer it on top of the beat. Like so.
It fills up your hat line, and fills up beat in general. It simply makes it sound intricate and it takes all of a few seconds. You can even mix and match different drum loops on top of the beat you made, and add a few subtle variations to your beat (like snare fills, etc), and as long as you don't overdo it, you can vary your drum beat nicely.
I know it's really cheap to just throw premade stuff on top of your beat, but it's a lifesaver of a method for whoever's like me, i.e. s/he has a strict schedule and isn't very good at all that sound design and mixing to make a good DnB beat entirely from scratch. Give it a shot!
