Swedish cinnamon buns

It's Waffle day tomorrow, not cinnamon bun day, but I was in the mood to make them anyway. Eating them when they're fresh out of the oven with a glass of milk is a flashback to my childhood. I used to stay with my grandma when she had 'bake days', and the entire kitchen would fill up with delicious cake and bread scents. Everyone makes different buns, but I like these swirl types. And it's important to add plenty of crystallised sugar!
