Beat the butter – In a large bowl, whip the butter on medium speed until it’s soft, smooth, and a little glossy. Think creamy clouds, not liquid butter.

Add powdered sugar – Slowly incorporate the sugar, one cup at a time. Beat well after each addition. Your arm won’t hurt—your mixer does the work .

Flavor it – Add vanilla extract (and salt if using). Mix until combined. Take a tiny taste—yes, it’s allowed.

Adjust consistency – Add milk, one tablespoon at a time. Want frosting for spreading? Add more. For piping? Keep it thicker. Simple.

Color & decorate – Drop in food coloring if you like rainbow vibes, then mix until fully blended.
