For the blueberry amarettini dessert, whip the whipped cream with the sugar until stiff. Mix the curd and vanilla yogurt in a separate bowl until smooth, then fold in the whipped cream. Place the amarettini in a bag, seal it tightly, then break the amarettini into coarse pieces with a rolling pin.
Defrost the blueberries if necessary and mash them. To layer, put some of the amarettini in a glass and cover with the cream, then spread some of the pureed blueberries on top. Repeat the process until the glass is full. Serve the blueberry amarettini dessert.
