For a smoother frosting, ensure your confectioners' sugar is freshly sifted to remove any lumps. If you prefer a richer peanut butter flavor, feel free to add an extra tablespoon or two of peanut butter. Spread the frosting while it's still warm for the best results. It sets quickly as it cools. This frosting is also delicious on brownies, cookies, or even as a filling for sandwich cookies.
