Sweet & Sticky Cinnabon Copycat Cinnamon Rolls

I have been meaning to make cinnamon rolls from scratch for some time now and I finally got around to doing it. They may take ALL DAY LONG, and you may get a little dirty, but the outcome is SO worth it. Taking your first bite of that warm and gooey cinnamon roll that you just spent hours creating, is probably the best taste ever, no really. Give it a go yourself and see what I'm talking about!
