Chocolate Zucchini Sheet Cake

I love Texas sheet cake. When it's zucchini time, I make this recipe, which resembles Texas sheet cake. What a sweet way to use zucchini from the garden!

    Great tasting bars with a generous quantity. Took to a party and got lots of compliments and recipe requests. Brought the pan home and the grandsons cleaned out all the crumbs in the pan! Followed the recipe with one change where I used regular milk in the frosting instead of evaporated milk since I didn't have any. It turned out just fine. A good recipe to keep in the zucchini rotation.

    Family loved it. The icing does something interesting when put on the hot cake. I liked how it turned out that way.

    Very good and moist. However, I prefer to put a chocolate icing on the cooled brownies instead of putting it on the bars when they are hot out of the oven. I used shredded zucchini that I thawed from my freezer and it worked fine (I drained a little of the juice that was in the bag of thawed zucchini, but I think it would have been fine had I not drained it..) Also, I recommend storing any leftover brownies in the refrigerator.

    Moist, delicious, and just the right amount of richness in this cake. The zucchini was hidden very well, too!

    This cake was delicious! Told the kids it had zuchinni in it when they were in the middle of their second piece. They were shocked and said it was a keeper and begged for more. These kids are picky eaters when it comes to veggies and this helped prove that veggies can be good (granted, it was in a dessert, but hey!).

    Everyone really loved this. But my husband wouldn't eat it because of the zucchini. Does anyone know if the recipe would turn out okay if I left out the zucchini?

    Made this in a 12" x 18" x 1 " pan and it was full to the top after I iced it! I don't know how it wouldn't overflow a 10" x 15" pan.Very moist. Awesome way to use up zucchini!
