I've only ever bought the chunks of frozen cassava as my local tesco sell it and I was curious, but it is very potato like.
Not sure the flour would work in western style cakes, but it is also known as manioc, tapioca starch and fufu if you are looking for recipes.
This is a link to a YouTube channel I watch which uses it. I found it when looking for what to do with the frozen cassava
