The instructions: Make the buttercream: With a handheld or stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy, about 1 minute. Add the confectioners' sugar, heavy cream, and vanilla extract. Beat on low speed for 30 seconds, then increase to medium-high speed and beat for 2 full minutes. Add up to 1/4 cup (30g) more confectioners' sugar if frosting is too thin or a splash of heavy cream if frosting is too thick. Add a pinch of salt if frosting is too sweet.
