In the bowl of a stand mixer, combine yeast & sugar with warm water and then wait until yeast proofs (about 5 minutes).
Add salt, oil & 2 cups of the flour. Mix on low with the paddle attachment to combine.
On low, slowly add the remaining flour until the dough is smooth.
Switch to the dough hook & knead the dough for 10 minutes.
Place the dough into a large, greased bowl. Cover & set in a warm place to rise for 1 hour.
Punch dough down & place on a lightly floured surface. Roll dough into one big log.
Divide that log into the number of breadsticks you want. (This will make approx 24 breadsticks)
Roll out each piece into a long, thin stick. Place on a parchment-lined baking sheet about 1-inch apart.
Cover the breadsticks with a towel (or lightly greased plastic wrap), & let rise until double in size; approx 30 to 60 minutes.
Lightly spray the tops of the breadsticks with cooking spray before baking.
Bake at 425 degrees for 12-14 minutes or until golden brown.
Melt the remaining butter in the microwave.
In a small bowl, combine the salt & granulated garlic - mix.
Remove breadsticks from oven & immediately brush the tops with the melted butter & sprinkle with salt/garlic mixture.
Enjoy warm. Store leftovers in an airtight container.
