There are more and more styles of birthday cakes, and I think the choice can be made according to your friend's personality.

1, usually like to do what things? Then you can make a similar cake, for example: playing basketball you can make a basketball cake, playing mahjong you can also make a mahjong cake and so on.

2, the character of openness can also prepare a kind of "devil cake", such as: the shape of the poop, the shape of the picture frame, etc., I believe that this is also a big surprise to friends.
