Whoops, didn't realize I got this a week ago.
I admittedly haven't been getting cake for my birthday as of the last few years, I just go to a nice bakery and get myself a bunch of pastries I like and call that my 'cake'. What I get varies depending on my current fancy or what's in stock.

But for the sake of curiosity if I were to choose a cake I really like those ones with the multi layers and gently sweet frosting with fruit slices in between the layers. Or I like a good cheesecake, caramel or some fruit I like. Or Tiramisu.
