I saw this made by Lance on Come Dine With Me Australia. I'm making it for a party we're hosting soon. I know it's not "authentic" but it looked good on the show. This recipe gave no serving, prep or cooking time. The cake mixes says they each serves 12, so I'm estimating you would get maybe 20 serves from the finished dish! Apart from cooking the cake, I reckon it took me around an hour to whip cream, butterfly cherries, assemble the cake and drink the leftover juice/cherry brandy!
