Well, I don't know, but I googled and this sounds like it might do the job - just leave out the cramberry sauce!
CRANBERRY-AND-CHOCOLATE TRIFLE
This is a stunning-looking creation of chocolate, cream and cranberries. It should be made in a deep glass bowl, to show off the layers of brown, white and ruby-red. If you don't have a suitable bowl and cannot beg, borrow or steal one, you can use a well-scrubbed goldfish bowl (just make sure you rehouse the fish first) or wide-necked flower vase. Prepare everything 48 hours in advance to allow the sugary chocolate to become gooey and sticky and begin to seep into the layers of creamy cranberry.
? 250g dark chocolate (55%-70% cocoa solids), grated
? 250g fresh wholemeal breadcrumbs
? 200g unrefined demerara sugar
? 2 tbsp cocoa, sieved
? 1 tbsp coffee granules
? 600ml double cream
? 300ml single cream
? 200ml crème fraîche
? 250g jar of luxury cranberry sauce
In a bowl, combine 200g of the grated chocolate with the breadcrumbs, sugar, cocoa and coffee. Sir well.
Whisk together the double and single cream until thick, but not stiff: this takes longer than usual because of the addition of the single cream. Fold in the crème fraîche.
In a large glass bowl, place a third of the chocolate breadcrumbs in a level layer. Top with a third of the cream and smooth it over. Carefully dot this with half of the jar of cranberry sauce, ensuring it is evenly distributed over the cream. Continue to layer in the same manner: chocolate breadcrumbs, then cream, the remaining cranberry sauce, more chocolate breadcrumbs and a final layer of cream. Cover with double foil and refrigerate for 48 hours.
Remove from the fridge and sprinkle the remaining grated chocolate over the top. Serve in small portions, since this trifle is extremely rich.
