I got this recipe from my friend Catharina, because she once prepared it and the cake was extremely soft and fluffy and great. I don't know were she originally got it, though.
Anyway, it's been my go-to white cake recipe since then.
Every time I have baked it, I filled covered the cake in dark chocolate ganache.
In one of such times, I also threw in pieces of banana. I'll tell you: this cake can't fail.
