A fudge cake is a small chocolate pastry that contains fudge. They are shaped as small round cakes, hence the name. "This recipe is also known as "Death By Chocolate, if topped with chocolate ice cream and lashings of whipped cream."  In addition to Death By Chocolate, there are many variations to it. One variation is the pudding fudge cake. To make the pudding variation, you mix these ingredients: chocolate cake mix,

chocolate pudding, chocolate chips.

Similarities
One could say that fudge cake is very similar to red velvet cake. Obviously, a fudge cake is not the size of a full-sized chocolate cake, it's more like a pastry. Fudge cake is also similar to almost every chocolate cake, just miniature. Mostly, a fudge cake is similar to a brownie. The only difference is that fudge cake is fudgier, and chocolatier.

Creation of fudge
About 100 years ago, fudge was founded by a woman named Emelyn Battersby Hartridge, a student at Vassar College in Poughkeepsie, New York. She wrote that her schoolmate's cousin made fudge in Baltimore, Maryland in 1886 and sold it for 40 cents a pound. Miss Hartridge got hold of the fudge recipe, and in 1888, made 30 pounds (14 kg) of fudge for the Vassar Senior Auction. Word spread of this confection to other women's colleges. (Wellesley and Smith have their own versions of this fudge recipe.)
