Fudgy Zucchini Brownies

"These moist fudgy brownies disappear fast at potluck dinners," reports Ruth Bramble, Rushville, Missouri. You won't even know there's zucchini in them.

    Definitely more cakelike, but no matter what you call them, they are delicious. I peeled the zucchini and omitted the nuts.

    Mine turned out pretty cakey, but I will try the recipe again as it was tasty.

    No one can tell there's zucchini in this recipe! Made according to directions except I added chocolate chips to the top because I knew I wouldn't have time to frost them. They are perfect and I wouldn't change a thing. As a volunteer food editor for Taste of Home, I love trying recipes with new ingredients added. Recipe can be easily cut in half, time was only about 5 minutes less.

    These brownies come out moist and yummy. More cake like than fudgy but very good. No egg needed.

    Very moist but seemed more like a cake than a brownie. Next time I would cut back in the sugar bvecause they were much to sweet for me.
