Eggnog Cinnamon Rolls

Step 1
Gather all ingredients.

Step 2
Combine sugar, yeast, salt, and 4 cups of the flour in the work bowl of a stand mixer fitted with the paddle attachment. Beat on low speed until just combined, about 15 seconds. With mixer running on low speed, add eggnog, sour cream, butter, and egg. Continue beating until dough forms, 1 to 2 minutes. Switch to a dough hook attachment. Beat on medium-low speed until dough is smooth and elastic, 6 to 9 minutes; gradually add remaining 1/2 cup flour, 1/2 to 1 teaspoon at a time, if necessary.

Step 3
Place dough in a large bowl greased with cooking spray and turn to coat. Cover with a clean kitchen towel and let rise in a warm draft-free place until dough has doubled in size, 2 to 3 hours.

Step 4
Spray a 13- x 9-inch pan with cooking spray. Lightly punch down dough. On a lightly floured surface, roll dough into an 18- x 10-inch rectangle.

Step 5
For the filling spread 1/2 cup of butter over the dough. In a small bowl, stir together brown sugar, cinnamon, and nutmeg. Sprinkle evenly over butter.

Step 6
Starting with one long side, roll dough into a log; pinch seam to seal.

Step 7
Slice into 12 rolls.

Step 8
Place rolls in the prepared pan. Cover, and let rise in a warm draft-free place until doubled in size, 1 hour to 1 hour and 15 minutes.

Step 9
Preheat the oven to 350 degrees F (175 degrees C).

Step 10
Bake in the preheated oven, uncovered, until golden brown, 25 to 30 minutes. Let cool in pan on a wire rack 15 minutes.

Step 11
Add cream cheese and 4 tablespoons butter to the bowl of a stand mixer fitted with the paddle attachment; beat on medium speed until smooth, 1 to 2 minutes. Add powdered sugar, eggnog, and vanilla. Beat on medium speed until smooth, about 1 minute.

Step 12
Drizzle glaze over warm rolls. Serve with freshly grated nutmeg sprinkled on top and any extra glaze, if desired.
