Peel and cut 3 large potatoes and boil them in a pot of salted water.
Once the water is boiled, reduce the heat, cover and let it simmer for about 20-25 minutes.
Check if the potatoes are tender and drain them. Dry the potatoes by turning on high heat for about 30 seconds then turn the heat off.
Mash the potatoes and add 1/2 cup whole milk and 1/4 cup butter. Mash and mix well until smooth and fluffy.
Season it with salt and ground black pepper, and mix again. Serve!
