For the blueberry whipped cream dessert, whip the whipped cream with vanilla sugar and sugar until stiff. Mix the apricot jam with the water until smooth.
Dip the biscuits in the apricot water and line a shallow baking dish with them.
Mix two thirds of the whipped cream with 100g of blueberries and spread on the sponge cake layer.
Mix the remaining whipped cream with the grated almonds and cover the biscuits with it.
Finally, spread the remaining blueberries over the dessert and drizzle with some leftover apricot water, if desired.
Leave the blueberry cream dessert to infuse for a few hours or the blueberry whipped cream dessert overnight.
