Bring a large pot of water to a boil.

Chop the carrots into even sizes, about 1" pieces. Boil in the water for about 15-20 minutes, or until a knife can easily be inserted and removed from the carrots.

Drain the water and add the carrots back to the pot.

Add in the butter, chicken stock, salt, pepper, and garlic powder.

Mash the carrots using a hand masher until evenly mixed.

To get the carrots extra smooth, puree the carrots using an immersion blender or food processor.

Taste to see if they need more butter or salt. Serve warm.
