Step 1

In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on medium-high speed for 6-7 minutes.

Step 2

With the mixer on low speed, slowly add in the salt and powdered sugar, and continue beating until the sugar is fully incorporated.

Step 3

Add in vanilla and cream or milk and mix on low speed until incorporated.

Step 4

Turn the mixer back up to medium-high speed and beat the buttercream for an additional 6-7 minutes.

Step 5

If the buttercream is too thick, add in a bit of milk, one teaspoon at a time until you reach the desired consistency.
