Chocolate Cake with Chocolate Mascarpone Frosting

 Simple baking is something that I like, no need for special equipment or technique, all you need is your time and a bit of attention ^^.

 As I always have Mascarpone in my fridge (don't ask me why, I have a habit of buying without thinking, haha), sometime I don't know what to do with it, and yes we can't eat Tiramisu everyday.
So I decided to use it as a frosting, but simple one is not good for me, I think about chocolate. Because the mascarpone has rich and creamy taste it goes well with something bitter or tangy ex: chocolate. So this time you don't need sugar thermometer to crate delicious buttercream, this one is very good both in texture and taste. I don't make mush icing sugar buttercream because I don't like the texture of it, but for this frosting, it's so smooth and creamy that you won't believe it made from icing sugar.
Forget about separating, you can beat this frosting (with mascarpone in it) without fear, the icing sugar and cocoa powder act like a glue so this time gentleness is not important ^^.
Serve this cake with a cup of hot coffee is the best as the taste of them come together so perfectly.
