I know these are pretty late, but if you can still find them out in the wild - spoiler alert - definitely get them. So yes, technically these were an Easter promotional KitKat in Japan (hence the bunnies) but I don't really get what pancakes have to do with Easter, or really, any season at all. The only holiday that I can vaguely connect to pancakes is Mother's Day, just because of all the mothers in advertising who love brunch.
It's the same format as Japanese KitKats usually are, small two finger bars in a sharing bag. These are special as the two fingers are fused together to create the ears of a bunny face. Pretty cute, but forget about splitting them in two. Frankly these are so teensy I don't think anyone would be sharing a single bar, anyway!
The flavor is intensely maple and therefore incredibly sweet. The crispiness of the wafers really does bring to mind the edges of a stack of diner pancakes with tons of syrup & melty butter.
I think these would make a really good permanent edition to some KitKat line, somewhere. They're very sweet so I don't think it's something you'd necessarily binge on, but a mug of coffee or tea coupled with one or two of these would make a very tasty treat, no matter what time of the year.
