For the smoothest buttercream, use properly softened room-temperature butter and sift the confectioners' sugar before mixing.

For a firmer piping consistency, use less heavy cream or add a little extra sifted confectioners' sugar.

For a softer spreading consistency, add heavy cream or milk about 1 teaspoon at a time.

For vanilla bean buttercream, substitute vanilla bean paste for some or all of the vanilla.

For chocolate buttercream, mix unsweetened cocoa powder into the finished frosting and add extra cream as needed.

For almond buttercream, replace part of the vanilla with almond extract, adding it gradually to taste.

For lemon buttercream, add finely grated lemon zest and a small amount of fresh lemon juice, reducing the cream as needed.

For colored buttercream, add gel food coloring after the frosting is fully mixed.
