In a large bowl using a handheld or stand mixer fitted with a paddle or whisk attachment, beat the cream cheese for 1 minute on high speed until completely smooth and creamy. Beat in the butter until combined. Add the confectioners’ sugar, cocoa powder, vanilla extract, 1 Tablespoon milk, and salt and beat on medium-high speed until combined and creamy. Add 1 more Tablespoon of milk to slightly thin out, if desired. Taste, then add another pinch of salt if desired.

Cover and store leftover frosting for up to 5 days in the refrigerator or up to 3 months in the freezer. After freezing, thaw in the refrigerator then beat the frosting for a few seconds so it’s creamy again.
