In a sauce pan, gently heat the milk over low heat until it reaches about 100℉ to 110℉. If it's particularly cold in your house, lightly warm your stand mixer's bowl by running hot water through it, then dry it out. Add the milk to the mixer bowl.
1½ Cups Milk
Add the sugar and yeast to the milk and give it a stir. Let this sit for around 10 minutes, until it starts to foam up.
¼ Cup Sugar, 2¼ Tsp Active Dry Yeast
Add the eggs, butter, and salt to the yeast mixture and beat it until it combines. Add the flour (gradually if necessary) and continue beating until the dough comes together.
3 Eggs, 4 Tbsp Unsalted Butter, 4 Tsp Kosher Salt, 6¾ Cups Flour
Turn the dough out onto a floured surface and finish kneading it, which will take about five minutes. You want it to be nice and smooth.
Lightly grease your mixing bowl with oil. Add the dough to the oiled bowl, turning to coat, and cover it with a tea towel or plastic wrap.
Let the dough rise for 1-1½ hours, until it has doubled in size.
Turn the dough back out onto the floured surface. Roll it out until it's a rectangle about an inch thick. Using a pastry cutter, pizza cutter, or knife, cut the dough into rectangles or squares; you want 24 pieces, however that works out with your shape.
Line your baking sheets with parchment paper (or silicone baking mats). Arrange the dough squares about half an inch or so apart on the sheets. Cover again with your towel and let rise again, for at least 45 minutes, until they have doubled in size again.
Preheat your oven to 375℉. Melt the ¼ Cup of butter and brush it on the rolls, then bake them for 15 minutes. You want them to start turning golden. Optionally, brush with butter again when they're done, and sprinkle with a bit of sea salt.
¼ Cup Unsalted Butter
Make the butter by mixing the ½ cup of room temperature (softened) butter, sugar, honey, salt, and cinnamon together. I found it easiest to do this with a rubber spatula for a thorough mix.
½ Cup Unsalted Butter, 1 Tbsp Powdered Sugar, 1 Tsp Honey, 1 Tsp Kosher Salt, ¾ Tsp Cinnamon
