Combine yeast with water and 1 tsp sugar, set aside for 5-10 minutes or until frothy (if yeast doesn't froth, then it is dead- either you need fresh yeast or your water was too hot and killed the yeast).
Add warm milk (again- warm, but not too hot or yeast will die), melted cooled butter,remaining 1/3 cup sugar, eggs, and just 3 cups of the flour.
Beat mixture until smooth- either with a dough hook in an electric mixer or using a spoon.
Next, this time using a spoon even if you have a mixer, stir in enough flour to form a soft dough ball (depending upon the hunidity of the day, you will need more or less flour).
Turn dough onto a floured board and knead until smooth and elastic, about 10 minutes, additional additional flour if needed to keep from sticking.
Place ina a lightly greased large bowl and then flip the dough over to coat top; cover with plastic wrap that has been greased (I use nonstick spray) and let rise in a warm place until doubled- about 1 hour.
Punch dough down, then place ona lightly floured board and divide inhalf.
Now divide each half into 12 pieces, shaping each piece into a ball.
Place 12 dough balls each into two 9x13 greased baking pans.
Cover as before and let rise until doubled, 30 minutes to an hour.
Bake in a preheated 375°F oven for 20-25 minutes or untilgolden brown.
