This isn't baking, but I think it fits into this thread. A friend told me the other day that she'd made a pretty good pudding by mixing together a ripe avocado and a ripe banana. She said some people like to mix in some cocoa powder too.

I thought it sounded weird, but when I got home I noticed that I had a ripe banana and a ripe avocado, so I mushed them up together. The mixture looked a little scary, but I tried it anyway, and -- surprise -- I liked it a lot!
