This two-layered cake is a bit of a show stopper as it looks like it has a ridiculously thick layer of vanilla cream cheese filling. The reality is that each of the two cakes form a peak when they cook, and when you invert one cake over the other (the base of one becoming the top of the cake), there's a gap which you pack out with the cream cheese filling. The salted caramel drizzle contrasts with the rich filling and the walnuts remind me of banana cakes I made as a child sprinkled with chopped walnuts.
