For the rolls:
- 3/4 cup eggnog
- 4 tablespoons unsalted butter
- 3 cups all-purpose flour
- 1 packet (2 1/4 teaspoons) active-dry yeast
- 2 tablespoons sugar
- 1 teaspoon salt
- 2 large eggs
For the filling:
- 1/2 cup (1 stick) unsalted butter, softened
- 1/2 cup light or dark brown sugar, packed
- 1 tablespoon ground cinnamon
- 1 teaspoon freshly grated nutmeg
For the icing:
- 1 cup powdered sugar, sifted
- 2-3 tablespoons eggnog
- 1 teaspoon vanilla extract
- 1/2 teaspoon freshly grated nutmeg
Step 1To make rolls, warm eggnog and butter in small saucepan over low heat until butter is melted. Remove from heat and cool 5 minutes, or until temperature reaches 120-130°F.
Step 2In bowl of stand mixer fitted with dough hook, combine 1 1/2 cups flour with yeast sugar and salt. Add warm eggnog mixture and mix until incorporated. Add eggs one a time, mixing after each addition. Add remaining flour 1/4 cup at a time until dough clears sides of bowl but is still sticky to the touch. Continue to knead dough in mixer until smooth and elastic, about 5-7 minutes.
Step 3Place dough in buttered bowl, cover with plastic wrap, and let rise in warm place until doubled, about 1 hour.
Step 4Gently punch down dough to release gases and knead a few times by hand. Reshape dough into ball, cover with plastic wrap and let sit for 10 minutes.
Step 5On lightly floured surface, roll dough out into large rectangle about 1/4-inch thick. Cover dough with 1/2 cup softened butter. For filling, combine brown sugar, cinnamon and nutmeg and sprinkle on top of butter.
Step 6Starting with one long side, gently roll up dough into one big log. Use sharp knife to cut dough into 12 equal rounds. Place in buttered 9x13-inch baking dish or 2 buttered 9-inch round pans. Cover with plastic wrap and let rise another 30 minutes. Meanwhile, preheat the oven to 350°F.
Step 7Bake rolls until golden, about 20 minutes. Let cool slightly.
Step 8To prepare icing, whisk together powdered sugar, eggnog, vanilla and nutmeg. Drizzle over warm cinnamon rolls. Let sit 5 minutes before serving.
Store leftover cinnamon rolls in an airtight container for up to 3 days.
