Ingredients

1 cup unsalted butter softened
3 1/2 - 4 cups powdered sugar
2-3 tbsp milk or cream
2 tsp vanilla extract
pinch of salt

Instructions

Beat butter for 2–3 minutes until smooth and pale.
Add powdered sugar gradually, mixing between additions.
Add vanilla, salt, and 2 tbsp milk.
Beat on medium-high for 2–3 minutes until fluffy.

Notes

Adjust texture:

too thick = add milk 1 tsp at a time

too soft = add powdered sugar

If you want a bakery-style finish, beat it longer than you think you need — extra air makes a big difference.
