Prinzregent Torte
A magnificent 8-layer Austrian cake, which always brings incredulous cries of pleasure
Delight Covill: I made this cake for my boyfriend on his birthday and he asked me to marry him (I did). I'm not saying for sure that the Prinzregent Torte is why Don wanted to marry me, but I've always worried that it might have been.
