Whip the heavy cream with the sugar and vanilla until stiff.
Set aside 1 cup of mixture.
Spread wafers with remaining cream and arrange in stacks of five.
Chill for 15 minutes.
Lay stacks on edge to make one long roll.
Spread remaining 1 cup of cream on outside of roll.
Cover and chill for at least four hours or overnight.
Garnish with chocolate curls or shavings before serving.
To serve, cut DIAGONALLY.
Note- To make chocolate curls you can slightly warm a large candy bar of good quality chocolate in the microwave (only a few seconds should do) Slowly scrape back of bar with a vegetable peeler and transfer curls using a toothpick, to a baking sheet or large plate/ Refrigerate until firm/ For shavings, I like to thinly slice miniature Dove Dark Chocolate candies (about eight or so) and sprinkle on your dessert.
