Belgian bun is a sweet bun containing sultanas and usually topped with fondant icing and half a glace cherry. The bun is round or square shaped, with rounded off edges, making it similar in appearance to a Chelsea bun. It is also sometimes served with cream
. No firm link has so far been established between the bun and Belgium; however, that country does produce as one of its specialties a very similar dessert (though with less icing) known as a couque suisse.
