Line an 8 to 9-inch square or round glass dish or bowl with ladyfingers. Douse with half of the liqueur, spray with a layer of whipped cream. Sprinkle with chocolate pieces and slivered almonds. Repeat this layering another time. After the second layering, spray a healthy shot of whipped cream on top. Dust with cocoa powder, garnish with raspberries and serve or chill until ready to serve.
