Natalie Zarrelli wrote about grooms that get their own cake:

• Until the 1940s it was tradition for a wedding to have two cakes – one for the bride and one for the groom.
• While the tradition has faded in parts of America it’s still strong in the south.
• The bride’s cake is the main one. It is larger and fancier and embodies the colours and the theme of the wedding.
• The groom’s cake is usually more representative of the groom’s personality and a way for them to leave their own mark on the wedding.
• Thus the groom’s cake might have R2-D2 on it, the logo of a favourite sports team, or be in the shape of an Xbox.
