Method
Make the dough
- Grease a 9x13-inch baking dish.
- In a large bowl, stir together the warm milk, yeast, 1/4 cup of the granulated sugar, and egg.
- Add the flour and salt, then mix in 1/4 cup of the softened butter; knead by hand or with a stand mixer for 8–10 minutes, until the dough is smooth and elastic.
- Place the dough in a lightly greased bowl, cover, and let rise in a warm place for 1–1 1/2 hours, until doubled in size.
Make the filling and assemble
- Stir together the remaining 3/4 cup granulated sugar, cinnamon, and cream of tartar.
- Roll the dough into a 12x18-inch rectangle.
- Spread the dough with the remaining 1/2 cup softened butter.
- Sprinkle evenly with the cinnamon-sugar mixture.
- Starting at a long edge, roll the dough into a log.
- Cut the log into 12 equal rolls and arrange them cut side up in the prepared baking dish.
- Cover the dish and let the rolls rise for 30–45 minutes, until puffy.
- Meanwhile, heat the oven to 350°F.
- Bake for 25–30 minutes, until the rolls are golden brown and the center rolls are baked through.
- Let cool in the dish for 10 minutes.
Make the icing
- Stir together the confectioners’ sugar, water, and vanilla until smooth.
- Drizzle the icing over the warm rolls.
Notes
For a soft texture, let the dough rise until doubled and the assembled rolls until puffy. Store covered in the refrigerator for up to 3 days; freeze baked rolls without icing for up to 2 months. For a dairy-free swap, use unsweetened non-dairy milk and plant-based butter.
