Vanilla can get a bad reputation for being bland. However, because of its easygoing flavor, it pairs so well with many flavors. You could always try something different, like a Biscoff buttercream or Oreo-flavored black frosting. Adding a filling like what you see here is another way to take a standard vanilla layer cake up a notch. Or decorate the top of it with whatever fruits are freshest and in season for you.
