Start by mixing together some ground cinnamon, sugar, and softened butter. You can adjust the amount of cinnamon and sugar to suit your taste preferences.
Make sure the butter is at room temperature so that it’s easy to mix with the cinnamon and sugar. You want the mixture to be smooth and creamy, without any lumps.
Once you have the cinnamon filling mixture ready, you can start spreading it on the rolled-out dough. Be sure to spread it evenly, leaving a small border around the edges.
If you want to add some extra texture and flavor to your cinnamon buns, you can also sprinkle some chopped nuts or raisins on top of the cinnamon filling before rolling up the dough.
After you’ve rolled up the dough and cut it into individual buns, you can sprinkle some more cinnamon and sugar on top before baking. This will create a delicious caramelized crust on the buns.
Lightly flour your work surface and roll out the dough into a 16×21 inch rectangle, making sure the dough is even in thickness.
Spread the cinnamon filling evenly over the dough, leaving a 1/2 inch border around the edges.
Starting from the long side, roll the dough tightly into a log, pinching the edges to seal.
Cut the log into 12 equal pieces using a sharp serrated knife or dental floss. To use dental floss, slide it under the log where you want to slice and cross the ends over each other, then pull tight to cut through the dough.
Place the buns in a greased baking pan, leaving a little space between them to allow for rising.
Cover the pan with a clean kitchen towel and let the buns rise in a warm, draft-free place for about 45 minutes to an hour or until doubled in size.
Preheat your oven to 350°F (175°C) and bake the buns for 20-25 minutes or until golden brown on top.
Remove the buns from the oven and let them cool in the pan for a few minutes before transferring them to a wire rack to cool completely.
