A fast-to-fix peanut butter and chocolate frosting tops these moist brownies that are a sweet way to use up your green garden squash. We really like the cake-like texture of these zucchini brownies. —Allyson Wilkins, Amherst, New Hampshire

"Would definitely call this a cake. It turned out fine but the peanut butter frosting is just wrong for this! I love pb and chocolate (even ate it as I was scarping it off!) but it was wrong for this cake."

"Turned out cake-like as others state, (I prefer Brownie texture). Frosting is delicious. It was difficult to spread thin enough to cover 13 x 9. Good if you enjoy cake, zucchini is not detected :), and frosting is yummy but should be doubled!"

"I definitely agree with the other reviewers, this is much more of a cake consistency than a brownie. However, it is a fantastic cake. The frosting is what makes it different from the usual chocolate zucchini cake. It's simple, but very rich. Perfect mix of sweet and peanuty chocolate goodness!"

"I was expecting Brownies and I got cake. I found an after taste of 'soda'. In general it was OK but I have had better cake made with zucchini. I won't be making this again."

"Really great light chocolate taste. Used glaze instead of peanut butter and chocolate chips."

"Good if you want a nice chocolate CAKE. You don't taste the zucchini at all. But not great if you're craving brownies.
