is a twinkie anything like a snicker?
I'm not sure what a snicker is.
A Twinkie is basically yellow sponge cake with a sweet creamy filling, kind of like whipped cream but very sweet. When they first were invented, they had a banana cream filling. The price of bananas rose so the switched over to just plain whipped cream.
In the US, we have a candy bar called Snickers which is chocolate covered nougat, caramel and peanuts. They are delicious.
