My father's birthday is next weekend. His grandmother used to make a cake that he remembers and my mother's never been able to duplicate it. It's now my job and I'm hoping someone can help. (And yes, I'm sure that what he remembers may have nothing to do with it in actuality, as that happens)
It's a 2 layer sponge cake, with whipped cream in the middle. All he remembers about the frosting was that his grandmother melted baker's chocolate in the double boiler and he doesn't believe there's any milk/cream in it, as every time my mother's made it with those it comes out much lighter in color than he remembers. He also said that it's a fairly stiff frosting but by the 2nd day becomes almost chewy (for lack of a better description by him, and he concedes that the chewiness may be because of the refrigeration and not anything about the frosting per se).
Any ideas? I'm hoping it's from some standard recipe from the late 40s/early 50s and my mom's just unable to figure it out.
Thanks in advance.
