For the dough, pour the water into a stand mixer with the sugar and yeast, let that sit and froth for about 10 minutes.
Add salt, butter, and 2 cups of flour. Mix the dough on low. Add the rest of the flour a half cup at a time, until dough scrapes the sides of the bowl clean. Mix the dough about 5 minutes on medium speed, until its soft and easy to work with.
Roll the dough out into a long log, spray a knife with cooking spray and cut the dough into 12-14 pieces. Roll those pieces into about 6 inch long snakes. Spray 2 large cookie sheets with cooking spray, and lay the breadsticks out leaving about 2 inches between each one.
Place them in the oven with the temperature turned to 170 degrees. Let them rise for about 15 minutes, or until doubled in size.
( I have also let them sit at room temp until they are doubled in size and then bake them in the oven) Once risen, brush them with the 1 1/2 T of melted butter and sprinkle them with salt. Now preheat the oven to 400 degrees and bake them for 12-15 minutes or until golden brown.
While they are baking combine the rest of the melted butter with 1/4 t garlic powder.
When the breadsticks are golden brown, remove them from the oven and brush them with the butter/garlic mixture.
