1. I am not able to make coffee > 2. I seem not to be able to make coffee > 3. I can't seem to be able to make coffee = 4. I am unable to seem to be able to make coffee = 5. I can't fake coffee-making or 6. I can't resemble someone who is making coffee.
"can" means "be able" so this sentence says the same thing twice, although it's grammatical. (Recall that grammatical doesn't necessarily mean sensible. "I can't let you have to be able to have to be able to see yourself when I might have to be able to have seen you" is perfectly grammatical from a purely syntactical point of view.)
