Place the cloves onto a cutting board and smash them using the flat side of a large knife, rolling pin, or bottom of a measuring cup. Peel the smashed garlic and put it into the pot of potatoes.
Bring to a boil. Once boiling, cover and cook 25 minutes, until potatoes are fork tender.
Drain the potatoes. In the same pot, melt the butter over low heat. Add the hot potatoes, milk, Parmesan cheese, garlic powder and onion powder and stir to combine.
