Both are tasty morning treats, but there are a few key differences. Sticky buns are baked upside down in a salty-sweet caramel sauce that turns all gooey and delicious in the oven. Plus, they're often rocking some crunchy nuts, like pecans, in the mix. Then, when you turn them out of the pan, the nutty caramel mixture cascades down the sides, much like a pineapple upside down cake.  Cinnamon rolls, on the other hand, are all about that cozy cinnamon and sugar swirl. You might find some basic icing or cream cheese frosting on top, but they're not nearly as sticky as their sticky bun brethren.
