In a small bowl, dissolve the sugar and yeast in the water and let sit for 5 minutes, until top becomes foamy.

In your stand mixer bowl {or regular large bowl}, combine 2&1/2 cups flour and the salt. Using the paddle attachment {or a good ol' fashioned mixing spoon}, mix the softened butter into the flour until well combined.

Add the yeast mixture to the flour mixture and use your dough hook and knead for about 8 minutes. Dough may be sticky, so if you need to, add a little bit more flour, until it stops sticking to the sides. Don't add more than 1/2 cup though.

Place the dough in a covered container and let sit for 1&1/2 hours, until doubled in size.

Once the dough has doubled, measure out 2 oz. portions of dough and roll each one into sticks that are about 7 inches long.

Place the dough sticks onto baking sheets and cover and let sit for 1 hour, until doubled in size again.

Preheat oven to 400ºF.

Bake the breadsticks for 10 minutes, or until just beginning to lightly brown.

Combine the melted butter and garlic salt and just after the breadsticks come out of the oven, brush them with the butter mixture, using a pastry brush.
