Step 1

With a handheld or stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy, about 2 minutes. Add 4 and 1/2 cups confectioners’ sugar, the heavy cream, and vanilla extract. Beat on low speed for 30 seconds, then increase to medium-high speed and beat for 2 full minutes. Taste. Add a pinch of salt if frosting is too sweet. I always add 1/8 teaspoon.

Step 2

You can control the consistency at this point– add up to 1/2 cup more confectioners’ sugar if frosting is too thin or more heavy cream if frosting is too thick (add only 1 Tablespoon at a time, beat together, then taste and add more if desired).

Step 3

Use immediately or cover tightly and store for up to 1 week in the refrigerator or up to 3 months in the freezer. After freezing, thaw in the refrigerator then beat the frosting on medium speed for a few seconds so it’s creamy again. After thawing or refrigerating, beating in a splash of heavy cream or milk will help thin the frosting out again, if needed.
