Begin by microwaving the milk and butter in a small bowl. The butter should be melted but the temperature should not exceed 110℉. If it is above 110℉, allow to cool for a few minutes.
Pour the milk and melted butter into a stand mixer and add the instant yeast.
Add the brown sugar, eggs, and pumpkin puree and mix until combined.
Add the bread flour, cinnamon, and salt.
Using the dough hook, knead dough for about 8 minutes, or until a soft dough is formed. This dough will be slightly sticky.
Cover the bowl and allow to rise in a warm place for 1 hour.
Step 2
Remove the dough onto a floured surface and roll the dough into a 12x18 rectangle.
Soften butter in the microwave for about 30 seconds. It should be soft enough to spread on the dough but not melted completely.
In a small bowl, combine the brown sugar and pumpkin pie spice.
Using a pastry brush, spread the butter over entire dough rectangle.
Sprinkle the sugar and spice mix over the buttered dough rectangle.
Starting with the short end of the rectangle, roll the dough into an 18-inch log. Pinch the ends of the dough to remove creases.
Using a very sharp knife, cut 12 equal pieces from the log. They should be about 1½ inches each. I find it easiest to cut the log in half, then half again, then in 3rds.
Place the rolls into the baking pan 3 wide by 4 long. Cover with plastic wrap and refrigerate overnight.
Step 3
Preheat the oven to 350 degrees.
Remove the rolls from the refrigerator and allow to sit at room temperature while oven is preheating.
Remove the plastic wrap and bake for 20 minutes.
After removing from the oven, allow the cinnamon rolls to cool while mixing the frosting.
Step 4
Using the stand mixer, beat the cream cheese, powdered sugar, salt, and vanilla on high speed. The frosting should be completely combined, smooth and slightly fluffy.
Add the cold heavy cream and mix on medium speed until cream is whipped into the frosting. It will be light and fluffy like whipped cream, just slightly thicker.
Frost the cinnamon rolls before serving. Because the frosting has cream and cream cheese in it, if entire pan is frosted, store leftover cinnamon rolls in the refrigerator. I store leftover rolls tightly wrapped in plastic, at room temperature so that they can be warmed in the microwave before frosting.
