When I was young and experimenting with vegetarian and health-food *stuff*, I used carob instead of chocolate to make chocolate milk. It’s different, but very good.
We also used to buy carob brownies at the local hippie store, and I have a feeling I made them once, and thought they were pretty good. Haven’t had any of this in decades, but here’s a link to a company that sells carob powder - and carob chips! - and their brownie recipe:

Thanks for the carob link!
