Roughly 110 calories per brownie. The great thing about these brownies are they are very forgiving if you overcook them! The banana, zucchini, and oat flour add depths of richness and moistness that make these brownies take a little longer to cook but resists drying out if you leave them in a few minutes too long (yes, i accidentally tried this). Definitely let them cool as long as you can before cutting though or you might end up with brownie crumble instead.
