My inspiration was the fresh figs in the grocery store. I used them to make a fig jam, to which I added ground hazelnuts.
Here are the layers out of the oven. I used the Classic Yellow Cake recipe from King Arthur Flour's Baking Companion.
I then spread the fig and hazelnut jam over each layer.
I then iced the cake with a chocolate ganache and sprinkled some more coarsely chopped hazelnuts on top.
Wow, this was a great cake. All the flavors came through clearly and well-balanced. I haven't seen pieces of cake disappear so quickly.
