Mix in vanilla extract. Taste here; add more if you love that floral note.

What Exactly Is Buttercream Frosting?

Buttercream is an emulsion of butter, sugar, and liquid flavorings, creating a versatile frosting that’s stable yet spreadable. Unlike royal icing (egg whites for glossy shine) or cream cheese (tangy, soft), this American-style buttercream holds peaks for rosettes and borders.

I’ve used it on everything from red velvet to vanilla sponge, and it never wilts even after 4 hours at room temp. Historically, it evolved from 19th-century French techniques, simplified for home bakers. Key science: Fat from butter traps air bubbles from whipping, while sugar dissolves into syrup for smoothness.
