Bring the chicken broth to a boil in a large pot over high heat.

Meanwhile, cut the unpeeled potatoes into 1 inch cubes or chunks. Place the potatoes chunks and garlic cloves into the boiling chicken broth and boil until potatoes are tender, about 15 minutes.

Add in the butter, cream cheese, buttermilk, and salt. Use a masher to mash the potatoes and other ingredients until everything is melted, combined, and completely mashed.
