I agree with regretful and tori to let H come up with desert. And since you are convinced he won't follow through, I suggest you ask him in a non-confrontational manner (while there is still time for him to recover) what desert it is he decided to make/provide.

Since providing desert was his idea, asking him about it is a perfectly harmless way to help him become more accountable for his words/commitments. If he drops the ball and you pick it up without a word, expect more of the same from him. If you complain after the fact... well you know how that will turn out.
