Wash and cut the cauliflower into uniform florets.

Boil salted water in a large pot, add the cauliflower, and cook until tender (about 10 minutes).

In a separate pan, melt the butter over medium heat until golden brown and nutty.

Drain the cooked cauliflower and transfer it to a mixing bowl. Add browned butter, garlic, heavy cream, salt, and pepper.

Mash until smooth using a potato masher or immersion blender.

Taste and adjust seasoning as needed before serving warm.
