In a large mixing bowl, whisk together 2 cups flour, sugar, yeast, and salt.

In a heat-safe bowl, combine the water and butter (cut into tablespoons). Heat in the microwave for 30 sec – 45 sec, until warm to the touch but not hot. The butter will not melt completely.

Pour into the dry ingredients with the egg and mix with a wooden spoon.

Add in 2 more cups of flour and mix. It should turn pretty thick and sticky at this point.

Add in 1/2 cup of flour and mix again. It should now turn shaggy and become difficult to stir. Once it reaches that point, set the spoon to the side and use your hands to mix and knead the dough.

It will be sticky, so add another 1/4 cup of flour and continue to mix and knead by hand. It should turn into a smooth mass that’s soft and tacky.

With a clean finger, press it into the dough. If your finger is sticking, add another 1/4 cup of flour and knead. If it’s not, then shape it into a ball and let it rest uncovered for 10 minutes.

When the 10 minutes is up, the dough should have puffed up quite a bit but not quite doubled in size.

Place the dough on a lightly floured surface and pat it into a rough rectangle shape. Roll it into a 10×15 inch rectangle using a rolling pin.

Spread the room temperature butter into a thin and even layer, leaving about 1/2 inch border all around the outside of the dough.

Sprinkle with the brown sugar and spread it even with your hand. Then top it with the cinnamon.

Working from the 15 inch end of the dough, roll it up into a log. Place your hands at each end of the log and give it a gentle squeeze in to compact the log of dough. It may have stretched out a bit during the rolling process so this brings it back together.

If using a sharp knife, gently saw back and forth and try not to press straight down into the rolls. This will squish them into an odd shape.

Cut the entire log in half, then cut those two halves in half to create 4 segments. Cut each of those 4 segments into 3 rolls to get a total of 12.

Place the rolls in a buttered or greased 9×13 dish (you could also use two 9″ round pans, placing 6 rolls in each). It’s OK if all of the rolls are touching.

Place in a warm spot and cover with a towel to rise for 1 hour. If you live in a colder climate, preheat the oven to the lowest temperature. Once it’s ready, turn the oven off and place the rolls inside. This creates a warm environment for the rolls to proof.

Preheat the oven to 350F (first remove the rolls if you proofed them inside) and check on the rolls. They should have doubled in size and now take up the entire dish.

Bake for 25-30 minutes or until the tops are a light golden brown. While they cool, make the icing.

Combine powdered sugar, melted butter, vanilla and milk in a large mixing bowl until smooth.

Pour over warm rolls and spread.
