I thought the idea was great to bake a cake filled, I bake a lot and otherwise well. A classic Rührkuchenrezept stuck despite numerous home remedies in the form. Twice baked shape, the flavor was good, but if the cake is a little higher, it is troublesome to remove the inner mold. After filling with smarties then broke up the cake. The weight of the filling was not great. So the result was quite modest, I had known, I would have saved my money and realized another idea. Maybe it really only the special recipe on the package with the original American ingredients. If so, then this should be stated.
