Step 1

Place the cubed potatoes in a large pot and cover with cold water by 2 inches.

Step 2

Bring the water to a boil and rapidly boil the potatoes until very tender and mashable, about 12 minutes.

Step 3

Strain the potatoes through a colander.

Step 4

While the potatoes are boiling, prep your stand mixer with a flat beater. Add the butter to the mixing bowl of the stand mixer.

Step 5

Pour the hot, strained potatoes over the butter in your mixing bowl and let sit for about a minute to let the butter melt.

Step 6

Lock the stand mixer and whip the potatoes on low just enough to mash them with the butter a bit. About 10 seconds.

Step 7

Add the sour cream, heavy whipping cream, chives, salt, and pepper to the potatoes. Whip the potatoes on low at first, increasing the speed to medium and then high until they are light and fluffy. Check on these every 20 seconds to see if they are blended enough, as you don't want to over whip them.

Step 8

Taste and whip in more salt and pepper if desired.
