The correct wording is "One and one is two."
( If you use the unambiguous word "plus", the answer is clear: One plus one is two.) One infers that this is a form of "The sum of one plus one is two." The singular verb form is also used in "One plus one equals two."
In this question, the word "and" is not functioning as a conjunction. You can tell the difference by applying a simple test. If it were a conjunction, you would be able to create a compound sentence that means the same thing. In this case, "One is two and one is two." Since that no longer has the same meaning, the word "and" is not a conjunction.
There is a case where you would correctly use the plural verb. If you were talking about multiple nouns rather than a numerical problem, then you would have a valid compound subject. For example:
"One spoon and one fork are two utensils."
This passes the deconstruction test:
"One spoon (is) (a) utensil and one fork (is) (a) utensil."
