In a large bowl, combine the chilled yogurt, cream, sugar, and vanilla (if using). Use an electric mixer to whisk for 2-3 minutes until the sugar dissolves and the mixture becomes thick and fluffy (reaching the soft peak stage). Taste and adjust sugar if needed.
Crush the biscuits in another bowl.
Grab your chosen serving dishes – either 3 individual dessert cups or 1 small serving dish.
Start with a layer of the yogurt mixture, followed by a layer of the crushed biscuits. Repeat until you've used up all the ingredients. This recipe goes heavy on the biscuits for that delightful flavor and texture.
Refrigerate for at least 4-5 hours, preferably overnight. Just before serving, decorate with your favorite chopped fruit, and voila – indulge and savor!
