Jimbalian fudge cake

A Jimbalian fudge cake

Jimbalian fudge was a type of fudge originating in the Delta Quadrant that could be used to make cake.

Neelix prepared a seven-layer Jimbalian fudge cake with icing made of puréed l'maki nuts for Kes' second birthday in 2371. (VOY: "Twisted")

In 2376, after losing his memory, Tuvok prepared many desserts, including a Jimbalian fudge cake with peppermint coulis, while he was being reeducated by Neelix. Tuvok drew a Ba'Neth frequency pattern on the cake's icing while trying to recover his memory. (VOY: "Riddles")

Kathryn Janeway appeared to have replicated a small cake like this for Tuvok after discovering his birthdate. (VOY: "Fury")

It may not have been an actual Jimbalian fudge, but it did seem to have pureed l'maki nut frosting.

In an alternate 2379, Neelix prepared a Jimbalian fudge for Kes on her ninth birthday. (VOY: "Before and After")

A recipe for Jimbalian fudge cake, adapted for terrestrial kitchens, can be found in the Star Trek Cookbook.
This dessert was spelled "Jiballian fudge cake with peppermint coulie" in the Star Trek Encyclopedia (4th ed., vol. 1, p. 390).
