In the bowl of a stand mixer fitted with the paddle attachment, beat cream cheese at medium speed until creamy, 3 to 4 minutes. In another large bowl, whisk together confectioners’ sugar and nutmeg. Gradually add sugar mixture to cream cheese, beating until smooth. Beat in enough heavy cream to make frosting a spreadable consistency. Beat in vanilla.
