Place the potatoes in a large pot and fill the pot with water. Salt the water, then bring it to a boil, boiling until the 2 ½ lb redskin potatoes are fork tender (about 15 minutes).
Drain the potatoes, then add them back into the pot. Use a potato masher to mash the potatoes to your desired consistency.
While the potatoes are cooking, add 8 tbsp salted butter to a pan over medium heat and allow it to melt. Then add the minced 4 cloves garlic and saute until the garlic is fragrant.
Once the garlic is fragrant, add the 2 stalks green onions and saute for another minute.
Then add ¼ cup milk, stirring until it is warm.
Add the milk mixture to the mashed potatoes along with ½ tsp sea salt, ½ tsp onion powder, and 2 oz cream cheese.
Stir to combine and add more milk according to texture preference. Enjoy!
