Prepare a cookie sheet by lining with parchment paper and set aside.
Set the yeast mixture aside in a warm place (100-105 degrees, ideally) to activate while preparing the other ingredients.
Add the arrowroot powder the yeast and water mixture and whisk together.
Reduce speed to low and add in the frozen butter shreds.
Using a piping bag, pipe out breadstick shapes onto your prepared pan.
Dust with garlic salt and sprinkle with parmesan cheese.
Allow the breadsticks to proof in a warm spot (ideally 100-105 degrees) for 1 hour.
After the 1 hour proofing time, bake the breadsticks in the preheated oven for 12-18 minutes until the bottoms are browned to your liking
Remove from the oven and allow to cool on the pan for about 5 minutes.
These are best served warm. Enjoy!
