Banana (Banana, Ascorbic Acid added to promote color retention)
Dark Chocolate ( Chocolate liquor (processed with alkali), sugar, cocoa butter, soy lecithin (emulsifier), and vanilla extract)
That's their ingredient list. I'd be willing to bet yours is shorter. And missing soy lecithin and a whole lot of sugar.
ETA: On the page where I found that info, all of the comments were about how you should make them yourself because you shouldn't be eating all of that... wait for it...
