"This cake is called "Tuxedo" because it is black and white as a "Tuxedo" . I buy it from a store here called Costco where you can find lots of delicious cakes, it is chocolaty (see ingredients), very decadent and just divine. I am warning you, however, that has a lot of chocolate and, for those patients with heart problems, is not recommended :-). I want to say two words about the cake (sponge) recipe, I found it on food-network posted by Betty Croker who is known for her recipes in the United States and Canada. To me, it is the best cake, extremely easy to make and very good, moist, moderately sweet (I might even say perfect), soft, it doesn't need any syrup and it has a gorgeous color ... and you'll love it so much that you will use it, certainly, for other cakes. It can be consumed as it is. And ... with this cake, we celebrated my husband birthday who really wanted me to reproduce the delicious cake Tuxedo that we usually by it and... I have to say that I really made it :-)..."
