Cream the Butter and Cream Cheese:

In a mixing bowl, beat the softened cream cheese and butter together with a hand mixer or stand mixer until smooth and creamy.

Add the Powdered Sugar:

Gradually add the powdered sugar, one cup at a time, mixing on low speed until fully incorporated.

Add Vanilla and Salt:

Stir in the vanilla extract and a pinch of salt. Beat on medium speed until the frosting is light and fluffy, about 2–3 minutes.

Adjust Consistency (Optional):

If the frosting is too thick, add a teaspoon of milk or cream at a time until you reach your desired consistency.

Use Immediately or Store:

Use the frosting immediately to top cakes, cupcakes, or cookies, or store in an airtight container in the refrigerator for up to 5 days. Let it come to room temperature and re-whip before using.
