In the bowl of a stand mixer, combine the yeast, 1 tablespoon of granulated sugar, and warm water. The water temperature needs to be 105 -115 F. Let the yeast proof for 5-10 minutes until foamy on top.
1 tbsp Active dry yeast, 1/4 cup Warm water
In a medium-sized bowl whisk the all-purpose flour, remaining tablespoon of sugar, and kosher salt together to combine.
2 tbsp Granulated sugar, 3 1/2 cups All-purpose flour, 1 1/2 tsp Kosher salt
In a large glass measuring cup add the whole milk and unsalted butter. Microwave in 30-second intervals until the milk is warm 105-115 degrees F(not hot) and the butter is almost melted.
1 cup Whole milk, 1/4 cup Unsalted butter
Add the milk mixture to the bowl of the stand mixer. Add the egg and whisk well.
1 large Egg
Using the dough hook, add the flour 1 cup at a time, and mix well. Then knead for 2 minutes. Remove the dough hook, cover the bowl with plastic wrap, and let rise for one hour.
Line two baking sheets with parchment paper.
Punch down the dough. Scrape the dough out onto a lightly floured work surface. Use a sharp knife to divide the dough in half. Place one half on the work surface, and cover the other piece while you are working with the first piece so it doesn’t dry out.
Roll the dough into a 12-inch circle. Melt 1/4 cup of butter in a small bowl. Brush a layer of melted butter over the surface of the dough circle. Using a pastry cutter or pizza cutter, cut the dough (like a pizza) into 8 equal triangles.
1/4 cup Unsalted butter
Starting with the wide end of each triangle (butter side up), roll the triangle. Roll them somewhat tightly. Place them point down on the prepared baking pan about 2 inches.
Continue with the remaining dough. Cover and let rise in a warm place until doubled in size, about 1 hour.
Preheat the oven to 375 degrees F while the crescent rolls are rising.
Bake for 10-12 minutes, until the tops are golden brown. Brush with melted butter, if desired.
