In the bowl of a standing mixer, combine 1 cup warm water, 2 tbsp warm water, 1 1/2 tsps instant yeast, 2 tbsps granulated sugar, 3 tbsps unsalted butter. Add in the 1 3/4 tsps salt. Attach the dough hook to the mixer and begin to gradually add the 16 oz bread flour on a low speed. Increase speed to medium and knead the dough for about 7 minutes, or until it is smooth and elastic.
Remove the dough to a lightly oiled bowl and cover with plastic wrap. Let rest in a warm place until doubled in size, about 1 1/2 hours.
Divide the dough into 12 (2 oz) portions. Roll each piece of dough into a 7-inch log. Place the dough logs on nonstick backing mat or parchment-lined baking sheets, cover, and let rise until double in size, about 1 hour.
Preheat the oven to 400 degrees. Bake for about 12 minutes, or until golden brown. Remove from oven and immediately brush with 2 tbsps unsalted butter. Combine the 1/2 tsp kosher salt and 1/4 tsps garlic powder and sprinkle evenly over breadsticks. Serve warm.
Notes
When it comes to bread baking, weighing your flour will always ensure the best and most consistent results. If you like to bake, consider investing in a kitchen scale if you don't already have one. It makes a big difference!
