Mix the flour, baking powder, and salt together and set aside.
Pour and mix the melted butter, warm milk, granulated sugar, and yeast in a bowl.
Let it sit for 1 full minute to activate the yeast.
Pour in 4 cups of the flour mixture and mix until just combined.
Cover with plastic wrap or a towel and set in a draft-free, warm area and allow it to rise for 1 hour. (It should double in size)
Remove the cover and place the dough and the last cup of flour, down on a surface to knead the dough.
Only knead in as much as is needed to take away most of the doughs stickiness. Don't know force in all of the flour if not necessary. You will end up with a dry, stiff dough that will not rise.
Roll the dough out into a large rectangular shape about 1/4 - 1/2" thick trying to make the corners as neat and even as possible.
Place the stick of butter on the dough and spread it out evenly all over the top.
Next sprinkle both the cinnamon and the brown sugar over the entire surface and pat into the dough.
Starting on one of the long-sides, roll up the dough forming one long log.
Use a sharp knife and trim up the ends and then cut the log in half and then cut each log into individual rolls. You can get 5-7 from each log.
Place them down in your prepared pans and cover with plastic wrap or a towel and again set in a warm area to rise another 30 minutes. The rolls should look fluffy.
Then place the rolls in the oven at 350°F for 25-30 minutes until golden brown.
Cover them in cream cheese frosting when you get them out of the oven and they are still warm.
Enjoy and share if you'd like :-D
