Peel and wash potatoes. If using gold or red potatoes, leave skins on if desired.
Cut potatoes into 1/2 to 3/4 inch chunks.
Put cut potatoes into a stock pot and fill with water until potatoes are covered by 1/2 to 1 inch of water.
Boil potatoes on stove for about 20 minutes, or until they are fork tender and edges of potatoes start to round.
Remove from stove and drain water from stock pot leaving potatoes. Transfer potatoes into a mixing bowl or leave in stock pot.
Push butter down into potatoes to melt and let sit for 2-3 minutes.
Use hand mixer on low to medium to do a rough beat on the potatoes to incorporate the butter.

Use hand mixer on medium to medium high to thoroughly mix and whip potatoes to desired smoothness.
Taste test and adjust to your liking.
