GudFud (pronounced "goood foood") is brand of stuffed marshmallow candies just introduced in the United States.
Stuffed marshmallows are not uncommon in Asia as a sweet treat (and can be found in Asian stores in the US) but have not been formally introduced here yet.
GudFud capitalized on the popularity of the candies is Japan and Malaysia and brands them for the American market. The first flavor varieties introduced here are the Chocolate Stuffed Marshmallows and the Fruit Jelly Stuff Marshmallows (grape, orange & strawberry).
The candies are currently available on the GudFud Website in sample packs and full boxes.
