I made this luscious looking cake a second time for a smaller group of friends. A half-recipe of the Nigella Lawson recipe I made the week before. I had some leftover frosting but not really enough to frost a cake with 2 layers, even a small one. So I made a raspberry filling, straining out the seeds from a jar of jam my friend Carol had made, adding butter and chocolate, and spread that between the 2 layers. I drizzled the fondant over the whole thing. The cake itself and the frosting (fondant) was lovely and delicious-ish, the raspberry filling just tasted like you hit a spot of sour.
I should know better than just wing it with stuff like this. I could have just asked the google.
