Mine is a white chocolate custard filled cake from the local bakery. Divine, but expensive :v so there's also a roll filled with guava jam or dulce de leche (latin sauce made of caramel and milk) that is very popular in my country and very good also.
My favorite kind of cake would either be ice cream cake or Boston cream pie, which is a cake despite the name. I also quite like chocolate cake and red velvet cake.
Cheesecake is so good omg. I love when it has a brownie bottom or chocolate marbling in it. It also needs to have a crust.
One time my sister was craving cheesecake so I bought a basic one, got some soft chocolate chips (like for baking) and chocolate syrup (the kind used for chocolate milk since I already had it) and DANG was that cake so good.
It's a toss between chocolate and lemon cake, even though in reality, I like almost all of the cakes that ever exist, unless it's savoury, or if it contains pineapple, lychee, kumquat, goldenberry and/or persimmon, since I don't like those fruits.
Cheesecake is probably my favourite, but only if it's original - I'm not a fan of the chocolate flavored one. Homemade coconut cake and icecream cake are my second favorite. Tasty but unhealthy :<
