Editor: Mick, what an interesting question! One thought is to try a waffle maker, with a thick brownie batter. Check out this post for some tips:
Also, this blog talks about using a panini press to cook brownies, and another blog does indeed show that you can grill brownies. We have baked bread on the grill, in fact, and we think that if you can regulate the temperature, this would be a great way to make a batch of smoky-tasting brownies!
Readers, any tips or good ideas for Mick?
