Correct spelling

hopefully

Correct spelling, explanation: to create an adverb we have to add suffix -ly to an adjective. In this case the base adjective is hopeful, so it ends with a consonant l. Thus, after adding the suffix we receive double l: hopefully. One l form, hopefuly, is therefore incorrect, and hopefully is the correct one.

Definition of hopefully:
adverb, in a hopeful manner; if everything goes well
Hopefully Jenny is on time today!
We worked hopefully, thinking that we could win.


Incorrect spelling

hopefuly

Incorrect spelling, explanation: hopefuly is incorrect, because after adding adverbial suffix -ly to the adjective hopeful, we receive hopefully. There is no reason why l wouldn’t double, so hopefully is the correct spelling of this adverb.
