I haven't tried this recipe yet. Looks interesting. Were I got it from didn't say servings. It's a complete guess. Also it didn't take 1 can of coke. I don't know how much they weigh so just use a can of it.Tell me what you think!! UPDATE Just made this, it wasn't that bad. Just be sure to grease the pan. I did have trouble cutting it though. It was very moist and soft. Almost too soft. Next time I make it I will try adding a egg or something to hold it together. Oh, and it doesn't really taste like a brownie. It's very caky. I guess the bubbly coke helps it to rise. Enjoy!!!
