Step 1

In the bowl of an electric mixer, add the milk and sprinkle on the yeast. Let sit until the yeast starts to foam, 1-2 minutes. Stir in the sugar, egg, egg yolk, and melted butter then stir in the flour and salt with a wooden spoon until everything comes together into a ball of dough.

Step 2

Knead with the dough hook on medium for 8 minutes. Alternately, knead by hand for 8-10 minutes on a floured surface. Lightly oil and large bowl and place the dough inside.

Step 3

Cover with plastic wrap and a kitchen towel and let rise for 1 to 1 and a half hours or until doubled in size.

Step 4

On a lightly floured surface, tip out the dough and roll out to a large, long rectangle, about 14 x 20 inches. Spread the butter evenly, all the way to the edges. Whisk together the cinnamon and sugar in small bowl then spread evenly onto the dough.

Step 5

Roll into a tight roll, and cut into 9 even pieces for an 8 x 8 or 9 x 9 inch pan. If using a 11 x 7 inch pan, cut into 6 pieces for giant rolls or 12 for smaller rolls. Place the rolls into the pan.

Step 6

Cover loosely with plastic and let rise in the fridge overnight. Or, if you’re wanting to bake right away, cover and let rise at room temperature for 30 minutes to 1 hour, or until doubled.

Step 7

When ready to bake, remove the rolls from the fridge and heat the oven to to let come to room temperature as the oven is heating up, about 30-45 minutes. Heat the oven to 350°F. Bake for 25-30 minutes, or until slightly golden and just cooked through or the internal temp comes to 190°F.

Step 8

While the rolls are baking, make the frosting by beating together the cream cheese, butter, powdered sugar, and vanilla (if using) until light and fluffy. Let the rolls cool for 5 minutes, then frost. Enjoy!
