Peel the potatoes. Then cut them into 1-inch chunks.

Rinse the potato chunks in cold water, and place in a large microwave-safe bowl.

Cover with plastic wrap and poke a hole to allow steam to escape.

Microwave on HIGHT for 10-12 minutes or until the potatoes are fork-tender.

Remove the bowl from the microwave.

Add butter and milk into a small bowl and microwave on HIGH for 1 minute.

Then add the butter mixture to the potatoes. Season with salt and pepper.

Mash using a masher or hand mixer until smooth and creamy.
