Homemade Vanilla Buttercream Frosting

This classic vanilla buttercream frosting recipe is smooth, fluffy, and not too sweet — just the way homemade vanilla frosting should be. It comes together quickly with a handful of ingredients and is easy to adjust to your preferred texture or sweetness.

This is my favorite buttercream frosting recipe for pretty much anything, but I especially love it as a treat between two chocolate chip cookies.

The key to this fluffy vanilla buttercream frosting is whipping it long enough to get that light, airy finish. It’s sturdy enough for piping but soft enough to spread on cakes and cupcakes without any fuss. Simple, reliable, and full of real vanilla flavor—this is the go-to frosting you’ll keep coming back to.
