Step 1

In the bowl of a standing mixer, combine the warm water and the yeast. Stir and then let the yeast sit for 10 minutes to proof.

Step 2

Add the sourdough starter and stir until well incorporated.

Step 3

In a separate bowl, whisk together the flour, sugar, and salt.

Step 4

Add the flour mixture to the yeast mixture and the vegetable oil to the standing mixer bowl.

Step 5

On a low setting, use the dough hook of the standing mixer to knead everything together. Continue to mix until the dough pulls away from and cleans the sides of the bowl.

Step 6

Turn out the dough onto a lightly greased surface and shape into a round.

Step 7

Place round in a lightly greased container with a lid. Let dough rest until double in size, about 45 minutes to 1 hour depending on kitchen temperature.

Step 8

In a small container, combine the cinnamon and sugar. Mix well and set aside.

Step 9

In a small container, melt the butter and set aside.

Step 10

Turn out the dough onto a lightly greased surface. Divide into four sections.

Step 11

Roll out one section into a rectangle. Brush one quarter of the butter onto the rectangle. Sprinkle one quarter of the cinnamon sugar over the dough.

Step 12

Starting at the longest edge of the dough roll toward the opposite side (so resulting dough is wider than it is long).

Step 13

Use unflavored waxed floss or kitchen scissors to cut the dough into 6 pieces. Place on a lightly greased baking sheet.

Step 14

Repeat with the remaining dough, butter, and cinnamon sugar to make a total of 24 cinnamon rolls.

Step 15

Cover the rolls and let rise for 30 minutes to 45 minutes until puffy.

Step 16

Preheat the oven to 400° Fahrenheit (204° Celsius).

Step 17

Bake the rolls for 16 to 18 minutes.

Step 18

In a mixing bowl, use an electric hand mixer to combine the cream cheese, butter, and vanilla extract.

Step 19

Mix in the powdered sugar and salt.

Step 20

A tablespoon at a time, slowly mix in the milk, until the frosting achieves your desired consistency.

Step 21

Frost the cinnamon rolls with the cream cheese frosting and enjoy!
