Roll half the dough mixture into a large rectangle, approximately 9" x 13". hot tip: if you don't have a rolling pin, it's perfectly acceptable to use any other cylindrically shaped item (wine bottle, water bottle, etc)
Spread half the mixture evenly onto the rolled dough.
Roll the longest end of the dough forward, creating a long log.
Cut your log into 12 cinnamon rolls and place in a 9" x 13" pan or put 6 in a 9" x 5". Leave some space as they will rise again.
Repeat with the other half of the dough to create 12 more rolls. hot tip: freeze one pan of cinnamon rolls for another day
Allow the cinnamon rolls to rise covered in a warm place.
Bake at 400°F for 15-20 minutes, until cinnamon rolls are fluffy and lightly browned.
