In a large bowl with an electric mixer on medium-high speed, beat butter until creamy, about 2 minutes. Add half of the icing sugar gradually, beating until light and fluffy, about 3 minutes, scraping down the bowl once or twice. Add remaining sugar, milk and vanilla and beat on high speed until silky smooth. If it is too thin, add a little more icing sugar. If it is too thick add a little but more milk. Frosting is now ready to use and best if used immediately.
Frost cupcakes or fill and frost cake once they are completely cooled. You can use a small offset spatula to create a casual look to apply frosting or use a pastry bag and star tip to create beautiful swirls.
The secret to super-smooth frosting is to beat it A LOT. It might need many more minutes than you expect, especially if any of the ingredients were cold. Just keep beating and you will be rewarded with creamy smooth frosting.
