To slice cinnamon rolls with a piece of sewing thread, cut a piece of thread about a foot long, slide it underneath the log of rolled-up dough, and cross the ends of the thread over the top in a scissor-like fashion to pinch off the dough.
If using THM Baking Blend instead of my baking mix, I recommend using about a cup of THM Baking Blend since it's not as dry as my baking mix. Please note that THM Baking Blend is not nut free.
I personally have never made these in the evening and waited to bake them until morning, but I know that some people have done that and had success with it. I don't recommend making them very far ahead and waiting to bake them because I'm sure the baking powder loses some of its potency and the rolls won't rise as much.
