Actually, they are both acceptable -- but under much different circumstances. When you mean "can't" use "cannot" -- that is a rule of American English. Don't let anyone tell you different.
However, there are RARE times when you want the "not" to modify a verb following it. In those cases, you can use "can not" but the meaning will be ambiguous. For example, if you're a vegetarian who has just been served meat you might think:
I can eat this, or I can not eat this and pretend that I did.
But, 99.99% of the time, the word you want is "cannot"

I was always taught "cannot" is the correct form and "can not" would be a spelling mistake.
The trouble is many people don't know this because of the widespread and constant use of the contracted form "can't".

Actually, both words are acceptable according to Merriam-Webster Online Dictionary. But personally, I use cannot.

The negative form of CAN is CANNOT. But, if you wish to express emphasis for a particular reason, people do often say "you can NOT!"
Also, as in saying, "well, you can not go, but say that you went".
It sounds very messy, though it is used.

It can depend upon the context.

Both are perfectly acceptable. However, it has become more common in recent years--thanks in part to the internet and instant messaging--to use the "cannot" version.

Cannot or can't, but I teach my children to say "I can try" instead!

It's still 'cannot'. I've never seen 'can not' used before.
