Grease a 9" X 13" X 2" cake pan, no parchment paper! set aside for later.
Combine all the ingredients for the sugar filling together in a small bowl, reserve for later
Combine the yeast with the warm milk & a pinch of sugar, let stand for 5 minutes
In a mixing bowl combine all the dry ingredients together & blend well
Add the milk with the yeast, the pumpkin& the softened butter to the bowl of your stand mixer & then add all the sifted dry ingredients.
Mix with the dough hook ~ you may need to help it along with a spatula until it forms a soft mass, then let it knead for 5 minutes on medium speed
Add flour to adjust the consistency as needed *see video demonstration
Turn mixer speed to low and mix for another 3 minutes
Once it is to desired consistency & properly kneaded for a total of about 8 minutes, turn out to a lightly floured surface and continue to knead until it is no longer super sticky to your hands of the table
Transfer to a lightly oiled bowl covered & let rise to double in a warm spot
Roll out onto a lightly floured surface to 12" x 18" & approx ½" thick
Brush with melted butter & then spread evenly with the sugar spice mixture
Roll up then cut into desired portions ~ cutting the log into 12 pieces for giant bakery size buns or 24 for smaller sized buns
Place them in the lightly greased 9" x 13" pan, cover loosely & let rise again covered in a warm spot. 35 - 60 minutes depending on the conditions in your area
Once they are fluffy & puffy & almost doubled in size (the buns will be almost touching each other) bake in a preheated 350°F oven for approx 35 - 45 minutes depending on the size of your buns * see video demonstration
While the buns are baking you can prepare the cream cheese icing recipe according to the recipe post on that page
Cool slightly then top generously with Cream Cheese Icing & a sprinkle of cinnamon
