"Hug me as tightly as how much you love me."
"Hug me as tightly as you love me."
"Hug me as much tightly as you love me."
Which is correct? Or any other suggestions?
Sentence one is correct and describes exactly what you mean, but it is awkward because of it.
Sentence two is also correct, and flows better because the "how much" is clearly implied.
Sentence three in not correct because you're using the adverb "tightly" to modify the quantity "as much", which is not a verb.
