Add the yeast and sugar to warm water and allow the yeast to bloom. This will take about 5 minutes. You'll know it's blooming when you see little puffs of expanded yeast float to the top and it gets nice and foamy.

Add the softened butter, salt, and 3 cups of flour to the bowl. Turn the mixer on medium speed and mix the ingredients until they are combined. Add in the remaining flour a little at a time just until the dough is only slightly sticky.

Knead the dough for 2 minutes on low speed until the dough is smooth.

Cover the bowl with plastic wrap or a tea towel. Let it rise in a warm place for 20 minutes.

Preheat the oven to 400ºF while the dough rises. Spray a 9x13 baking dish with nonstick spray.

Remove the cover on the bowl and punch down the dough. Divide the dough into 20 equal pieces.

Roll each piece of dough into a smooth ball and place them in the pan. You want to stretch the top of the ball and pinch the bottom together so that there is a smooth top.

Brush them with melted butter and let them rise an additional 15 minutes.

Place them in the oven, uncovered for 13 minutes. Turn on the broiler and broil them for 1 minute to get the golden brown tops.

Remove the rolls from the oven and brush them with butter. Sprinkle the tops with coarse salt and enjoy!
