Make the dough. In a large mixing bowl, whisk together the water, pumpkin puree, sourdough starter, coconut oil, and honey.
Add the flour and mix/knead together with the other ingredients until the dough forms into a ball. Knead until all ingredients are well combined and dough is starting to feel a bit elastic.
Grease a mixing bowl with coconut oil, add the ball of dough to the bowl and cover with plastic wrap or beeswax wrap. Allow to ferment at room temperature for 8-12 hours or until doubled in size.
After the Fermentation Time
Add the dough to a stand mixer with a dough hook. Add egg, vanilla, pumpkin pie spice, cinnamon, baking powder, baking soda, and salt. Mix until combined. Grease a 9 x 13 baking dish and set aside.
In a separate medium bowl, mix together filling ingredients. Add softened butter, pumpkin puree, brown sugar, pumpkin pie spice, and cinnamon. Mix well and set aside.
On a lightly floured surface, roll dough out into a large rectangle, about 12" x 18".
Spoon the filling over the dough, spreading it out evenly, avoiding the very edge.
Roll the dough up tightly into a log shape and pinch to seal seam. Cut into 12 rolls with unflavored dental floss or a sharp knife. Place rolls in prepared baking dish. It’s okay if the sides are touching.
Warm heavy cream slightly, and pour cream around and in between rolls. Cover baking dish and allow rolls to rise for 30-60 minutes. When rise time is almost up, preheat oven to 350 degrees F.
Bake for 30 to 40 minutes until rolls are golden brown and centers are cooked.
Maple Cream Cheese Frosting Instructions
While the pumpkin cinnamon rolls are baking, make the frosting.
In a mixing bowl (or the bowl of a stand mixer), blend softened cream cheese and butter together. Add powdered sugar, maple syrup, cinnamon and vanilla. Beat until smooth.
Spread frosting over warm rolls and serve.
Store leftover frosted rolls in the refrigerator.
Notes
You’ll need a mature starter to make this sourdough pumpkin bread. If you don’t have a starter yet, go here to learn how to make one.
Instead of canned pumpkin purée you can make your own pumpkin puree with a fresh pumpkin following these instructions.
Instead of the pumpkin pie spice called for in the recipe, you can use a combination of equal amounts of ground cinnamon, ground cloves, ground nutmeg, and ground allspsice.
Add another 1/4 cup of powdered sugar to the frosting if it's not sweet enough.
