Yep! I read this recipe too and even while I was making them I was thinking there was no way they would turn out well nor fly with the kids. But they are super yummy! The only questionable part is that you can actually see little specks of green. So I'm calling them "energy brownies", telling the kids that they are a treat, but they also give them a little energy (which is partially true with having something like kale in them, right?) :)
Sidenote: Next time I'm going to try them with less oil. The recipe called for what seemed like a lot. I also was able to cut back on the sugar and only do the 1/2 cup.
