Avoiding experimenting with fats
The perfect, soft cinnamon roll is heavily reliant on fat. There are many recipes that use butter as the primary fat, but there is a whole world of fats available besides this dairy-based option. If you want to make vegan cinnamon rolls, you should look for a vegan butter stick. The flavor of vegan butter is similar to that of dairy-based butter, but it is typically made from a blend of plant oils.
Coconut oil is another option for vegan cinnamon rolls. Because refined coconut oil does not have the same coconut undertone as unrefined (or "raw") coconut oil, it is preferable for a non-tropical flavor. If you want to use coconut oil instead of butter in cinnamon rolls, keep the coconut oil solid or melt it depending on the recipe. In both solid and liquid applications, a 1-to-1 ratio of coconut oil to butter can be used.
