A creamy and smooth vanilla buttercream frosting perfect for cakes and cupcakes.
In a large mixing bowl, beat the unsalted butter until creamy and smooth.
Ensure the butter is at room temperature for easier mixing and a smoother texture.
Gradually add the powdered sugar, one cup at a time, beating well after each addition.
Sift the powdered sugar beforehand to avoid lumps in the frosting.
Mix in the vanilla extract and milk, and continue beating until the frosting reaches a smooth and spreadable consistency.
If the frosting is too thick, add a teaspoon of milk at a time until the desired consistency is achieved.
Use the frosting immediately or store it for later use.
For piping, chill the frosting slightly to help it hold its shape better.
