1/3 cup warm water, 110 – 115 degrees
2 1/4 tsp active dry yeast
1/3 cup + 1/4 tsp granulated sugar
1 1/3 cups whole milk, warmed to 110 – 115 degrees
3/4 cup salted butter, at room temperature, divided
1 large egg, at room temperature
1 1/2 tsp salt
4 1/2 cups all-purpose flour*
Measure out warm water into a liquid measuring cup then stir in yeast and 1/4 tsp sugar, whisk until yeast has dissolved then let rest 5 – 10 minutes until mixture is foamy. Pour yeast mixture (scrapping out excess) into the bowl of an electric stand mixer fitted with whisk attachment, add in 1/3 cup sugar, warm milk, 5 Tbsp butter, egg and salt. Blend mixture until combine. Add in 2 cups flour and mix until well combine. Switch attachment to a dough hook, with mixer on low speed, slowly add remaining 2 1/2 cups flour and mix until dough is smooth and elastic, about 4 – 5 minutes (dough should be slightly sticky when touched). Transfer dough to a greased, large mixing bowl and cover bowl with plastic wrap. Allow dough to rise in a warm place, free from draft, until double in size, about 1 1/2 hours.
Punch dough down and divide dough into two equal portions. Shape each portion into a ball. Roll each dough ball out on a lightly floured surface into a large circle about 13 inches across (try to keep dough as much of an even thickness as possible). Spread each circle of dough evenly with 2 Tbsp butter. Cut each circle into 4 equal quarters, then each quarter into 3 wedges (just imagine cutting pizza slices or pie slices). Roll each wedge up, beginning on wide (outside) edge. Transfer rolls to a buttered 10 x 15 inch cookie sheet (the tip of the rolled wedge should be tucked on the bottom. Note that you can fit 3 rows of 8 rolls). Cover rolls loosely with plastic wrap and let rise in a warm place until double in size, about 1 hour. During the last 10 minutes of rising preheat oven to 375 degrees.
Remove plastic wrap and bake rolls in preheated oven for 15 – 19 minutes until golden brown. Remove from oven and brush with remaining 3 Tbsp butter (you may not need all of it). Serve warm or allow to cool and store in an airtight container.
