Step 1

For the dough, combine the sugar and butter in a stand mixer fitted with the dough hook attachment

Step 2

Mix on low speed, adding the salt when the sugar and butter start to come together

Step 3

Add the eggs and vanilla and mix on medium speed

Step 4

The mixture will look chunky

Step 5

In a medium bowl, combine the flours and yeast, then add to the sugar mixture and mix on medium to high speed

Step 6

When about half of the flour is incorporated, slowly stream in the water and continue to mix until the dough comes around the hook

Step 7

It will be sticky

Step 8

Remove the dough and knead on a floured surface

Step 9

Shape into a ball, put into a greased bowl and cover with a towel

Step 10

Place in a warm spot (such as on top of the stove) to proof until almost doubled in size, about 1 hour

Step 11

Meanwhile, prepare the sugars for the filling

Step 12

Place the brown sugar in a small bowl and set aside

Step 13

In another small bowl, stir together the granulated sugar and cinnamon and set aside

Step 14

When the dough is ready, grease a 9-inch cake pan and set aside

Step 15

On a floured surface, roll the dough into a large rectangle horizontally that is about 14 inches wide from top to bottom

Step 16

(Note: it will spring back as you roll it

Step 17

) Brush the melted butter on the entire surface, reserving just a little for the top

Step 18

Sprinkle all of the brown sugar over the surface of the dough

Step 19

Next, sprinkle the cinnamon-sugar mixture over the brown sugar, reserving just a little for the top

Step 20

Using a pizza wheel, cut the dough into horizontal strips about 2 to 3 inches wide

Step 21

Depending on how big your dough rectangle is, you will end up with 5 or 6 strips

Step 22

Take the top strip, roll it up into a circle and place it in the center of the prepared cake pan

Step 23

Working with 1 strip at a time, roll it around the center piece, building a giant cinnamon roll in the pan

Step 24

(If the strips are too long to handle, cut them in half to make it easier

Step 25

)  When you've used the last strip and the cinnamon roll is formed, brush the remaining butter on top and dust with the remaining cinnamon-sugar mixture

Step 26

Cover with a towel and place in a warm spot to proof again, this time for about 15 minutes

Step 27

The cinnamon roll should fill up the pan

Step 28

Meanwhile, preheat the oven to 300°F

Step 29

When the dough is ready, bake for 40 to 50 minutes, or until a toothpick inserted in the center comes out clean

Step 30

While the cinnamon roll bakes, make the icing

Step 31

In a large measuring cup with a spout, whisk together all of the ingredients until smooth

Step 32

When the cinnamon roll comes out of the oven, immediately pour and spread the icing over the top

Step 33

The heat will melt it into the roll's folds

Step 34

(The middle of the roll may deflate a bit as the icing melts in

Step 35

)  Cut into portions and enjoy!
