Whip Cream: In a large mixing bowl, combine cream, sugar, and vanilla. Beat with an electric hand beater or stand mixer on medium speed until soft peaks form, about 3–4 minutes.
Add Brandy (Optional): Gradually pour in brandy, one tablespoon at a time, and mix until combined. Avoid overwhipping.
Form Base: On a large round serving plate, dollop whipped cream in a circle to create the wreath base, leaving space around the edges.
Assemble Biscuits: Spread about ½ tablespoon of cream onto the flat side of a biscuit, place another on top, and stand them upright on the cream circle. Continue sandwiching biscuits with cream, forming a wreath shape.
Cover Cake: Use the remaining whipped cream to coat the entire wreath evenly. Smooth with a spatula.
Chill: Refrigerate for 6–8 hours or overnight until the biscuits soften and the texture becomes cake-like.
Decorate & Serve: Before serving, use extra whipped cream to stick on gingerbread cookies or decorate with fresh berries, chocolate shavings, peppermint crisp, or festive candies. Slice and enjoy!
