Gansito ( Spanish "little goose"), is a Mexican snack cake, which some people think taste similar to Twinkies, with the exception of strawberry jelly along with the creamy filling and that it is covered in chocolate with chocolate sprinkle topping. It was created in 1957 by Marinela (the pastries division of the breadmaking Bimbo brand). Gansito is one of the first three products to emerge from this brand. This specific snack cake is heavily marketed, possibly more than any other of Bimbo's products which include white and wheat bread, cereal bars, pound cakes and several other cakes, various pastries, cookies, and wafers.
The 1.8 oz packs 200 calories, 8 grams of fat of which 8 grams are saturated fat, and less than 9 percent of any vitamin, though it is marketed as being vitamin enriched.
The Gansitos are sold all over Mexico.
