Layer the cake with even buttercream layers and trim the top with a serrated knife to make it flat.
Before adding frosting, make sure the cake layers are set in the fridge for a few minutes to keep the shape when decorating.
Before adding the frosting, apply a thin crumb coat to seal the layers so the frosting can be spread evenly.
Make sure the buttercream you're using for frosting is not too thick and evenly spread out, revealing the inner layers.
Decorate with simple embellishments like rustic flowers and herbs to enhance the naked feel.
