In a mixing bowl, whip the cream with icing sugar and vanilla until soft peaks form.
Gather a nice serving dish and spread some whipped cream on the bottom. This will help the biscuits to stand on their edge.
Set up two shallow bowls — one with L&P and one with sherry.
Dip each biscuit briefly (1–2 seconds only) into the liquid.
Arrange dipped biscuits in a vertical line on your serving board or plate. The biscuits will stand up in a line on its edge. (best to watch how on the video). Spread whipped cream between each biscuit to help them stick together.
Once assembled, cover the entire log with the remaining cream. Use a spatula to smooth the outside.
Press halved strawberries around the base for decoration.
Sprinkle generously with crumbled chocolate flake over the top.
Refrigerate for 4-8 hours, but best overnight— this allows the biscuits to soften into a cake-like texture.
Slice and serve chilled.
