1.Don't you just dare...
2.Don't you even dare...
In the variant of English I am familiar with as a native speaker, (1) is incorrect and is a confusion with a different idiom. To give all the rules would take up a lot of space so I'll give some examples and offer a way to research this more.
I am used to hearing:
Just don't [you] dare.
Don't [you] even dare.
Don't you just love that?
