Although it's clear we made a banana cake and even though you can find the ingredients down below, this is actually a mystery recipe. I'd forgotten to buy the sour cream of the original formula so I had to make do with what I had: I beat the egg whites instead of having them runny and added a dash of milk and maple syrup. My quick thinking turned this looming disaster into a surprise success. But my boyfriend just ate the cake, without concern for the process that made it be, and that's a real mystery. All I got was praise for the end result.

What's more, I made a banana cake of sorts before, which he wasn't too fond of. He seemed to like it a whole lot more this time over, but still no questionnaires.
Since I just have to share, I'll do it here. Hope you'll like it!
