Much as I like cinnamon rolls, their sweetness is sometimes a bit too much for local temperatures. So, when I saw a video of "tray rolls" on skillshare (can't locate it just now), I decided that I have to have a go at various different fillings for the rolls; also to make them stuck together as they suggested. Two reasons: one, mentioned in the video, is that you hide most of the edges of the rolls as you stick them together, so they don't dry out in the oven.
