Stir together butter, brown sugar, cinnamon, and flour until it forms a paste.
Spray an approximate 9x5” loaf pan with cooking spray.
Once the dough is risen, roll it out on a lightly floured surface into a large rectangle, about 10” by 14”. Slice into 18 sections. Spread a little filling on each section, except for one (that will be your last piece, you don’t want the filling touching the end of the pan).
Stack half of the sections and place in prepared pan. Stack the second half and place them in front of the first, making sure that the ends touching the ends of the pan have no filling on them. (You need to stack them in two sections because otherwise the weight of the top of the stack with seal the bottom of the stack together and it won’t be “pull-apart” anymore.) The stack won’t totally fill the pan, but it will once it rises again.
You have two ways to continue. (1) let pan rise for 1 hour at room temperature then bake as directed or (2) cover pan with plastic wrap and refrigerate overnight.
When ready to bake, preheat oven to 350°F. Remove the rolls from the refrigerator (if you chilled them overnight) and let them warm up to room temperature while the oven is preheating. Remove the plastic wrap and bake for about 25 minutes, or until they are golden brown.
