Navone's cake – which has been crafted in Häagen-Dazs's Paris flagship store – features 31 ice cream-filled columns of varying heights, intended to represent the 31 days from 1 December to New Year's Eve.
The designer has described the cake as "like an explosion of ice cream bricks".
"The design speaks of a refined sophistication and a playful pop," she added. "It may be split into cubes like a game for all to play and consumed day to day or within a moment."
A solid piece of white chocolate tops the dessert, which is covered in numbered milk-chocolate tablets. Christmas Eve and New Year's Eve are marked out with chocolate squares covered in edible gold or silver leaf.
The cake is available in two versions: dark chocolate and almond with a brown flocked covering, and macademia nut brittle and dulce de leche with a red coating. Both editions have crispy bases, made from puffed rice.
Last year's Häagen-Dazs Christmas cake, designed by Nendo, was topped by a miniature chocolate village created to remind people of going home for the holidays.
Other designer cakes covered by Dezeen include sweet treats created by Viktor & Rolf and Studio Job for Design Miami, and Lucy.D's updated version of "kitsch" Viennese cakes for historic Café Landtmann.
