Peanut butter cookies, into which I substituted rice milk. It was okay, but *very* crumbly. Probably needs gluten-free flour-or-something, or another binder like xanthan gum.
Rice pudding, which I totally didn't do this way - I didn't realize it wanted uncooked rice, so I wound up with soup, and then I added a cup of uncooked arborio rice afterward and did it as a makeshift maple-cinnamon risotto.
So next time, I'll totally just make the rice pudding as a sweet risotto from the get-go (using rice milk, not broth). It came out great.
