Whip the cream. Dip the ladyfingers or egg biscuits on both sides in Prosecco or (if children are also eating) in a mango syrup-water mixture. Tip: Pour the liquid into a soup plate, for example, and briefly turn the ladyfingers or egg cookies in it. Layer a layer of soaked biscuits or egg biscuits in a table-size dish or in portion glasses (advantageous for round glasses). Then spread about 1 cm of cream on the biscuits, cover the cream with mango puree. Repeat this process at least one more time, depending on the height of the shape. The finish should be a layer of mango puree. Cover and chill for approx. 4 hours.
Decorate as you like - for example with remaining, halved egg biscuits.
To serve, cut off the appropriate portions or serve in the small glasses - garnished a little.
