First, place the potatoes, chicken broth, 1 tablespoon salt/pepper, garlic powder, and butter in the slow cooker. Cover and cook on low for 4 hours and 30 minutes.
Next, drain extra liquid, add sour cream, and chives. Mash lightly until the potatoes are a chunky mash.
Now, mix buffalo sauce ingredients and add to potatoes. Also, add blue cheese and scallions.
