In a large bowl, mix together all the dough ingredients and knead until smooth; about 15 minutes by hand. Add more flour as needed to prevent sticking.
Form the dough into a ball and let rise in the bowl for 1 hour, covered, or until doubled in volume.
When the dough is almost done risng, make the filling (choose one or both):
-combine the cinnamon + sugar + vegan butter
-melt the chocolate chips
Once the dough has risen, transfer it to a lightly floured surface and roll it into a 12 x 15 inch rectangle. Spread on the filling mixture(s).
Roll the dough lengthwise into a tight log, then cut into 12 equal pieces. Place into a greased baking pan and let rest for 30 minutes, or until risen 1.5x in volume.
Bake the rolls in a preheated oven at 350F / 180C for 30 minutes, or until slightly browned. Let cool before enjoying.
