I need to make a birthday cake, this afternoon, not super sweet, special birthday. Ideas?

Japanese cheesecake, always light and not as sweet as American dessert https://www.youtube.com/watch?v=2xxM3xWp-uQ , http://www.justonecookbook.com/souffle-japanese-cheesecake/, great with strawberries.

I have made this olive oil cake: https://food52.com/recipes/26709-maialino-s-olive-oil-cake several times, and it is quick easy and good. I used a whipped ricotta icing as suggested by some one else and decorated it with slices of pink cara cara and orange naval oranges. It looked good and was popular.

I made this cake recently. It is very rich and I'd suggest serving it with some whipped cream. https://food52.com/recipes/40653-ooey-and-gooey-double-baked-chocolate-cake
