  1. Preheat an oven to 350 degrees F (175 degrees C). Grease a jelly roll pan.
  2. Sift flour, cocoa powder, baking soda, and salt together in a bowl.
  3. Beat the butter and 1 1/2 cups sugar with an electric mixer in a large bowl until smooth. Beat the first egg into the butter until completely blended, then beat in the vanilla extract with the last egg. Mix in the flour mixture until just incorporated. Fold in the zucchini; mixing just enough to evenly combine. Pour mixture into prepared pan. Sprinkle the remaining 2 tablespoons sugar, chocolate chips, and walnuts on top.
  4. Bake in the preheated oven until the top is dry and the edges have started to pull away from the sides of the pan, 25 to 30 minutes.

I made these brownies without changing anything except the topping (I omitted the sugar and just used 1.5c of chocolate chips), and they were perfect! I would consider them more of a cake than a brownie though. They are so delicious (you would never know there was zucchini in these!), we even ate them for breakfast! *I did bake them in a 13x9x2 dish, instead of a jelly roll pan, which probably just made them thicker. It baked at 350 for 30 minutes.

Okay if you're just trying to use Zucchini but it was not anything like a brownie. It was like cake and nothing more. Will look for another recipe or more likely adapt a real brownie recipe myself. Was very, very disappointed. Had wanted something rich enough to pair with vanilla ice cream. Too late to make something else for guests.

LOVE IT! I've tried many and always ended up too cake-y (in defense of the recipes, I've also tried to substitute applesauce which I've learned changes the texture. They were moist and chewy. My husband said "these are REALLY good" and he mocks anything sweet with vegetables in it.

Good flavor. After tasting it, found it to taste much like my mother's sheet cake, so decided to add the frosting that would be on her sheet cake. My family loved it with the frosting.

This was a big hit! I did not use the walnuts and I used Splenda for the sugar. After I pulled out of the oven I took a spatula and spread out the chocolate chips to make it look like icing. All my family and friends loved them, even asked me for the recipe. Great way to get picky eaters to have some vegies!!

Delicious! My family absolutely loved these and had no clue that there was healthy zucchini in there. I thought they were more cake-like than brownie, but it may have been because I used a 9x13 pan instead of a jelly roll pan. But, in any case they were just the right amount of sweet and chocolatey goodness. These are going to be a definite keeper in my house!

I had extra shredded zucchini after making Zucchini Bread, was looking for something to use it up, and stumbled upon this recipe. I didn't sift anything, was not real exact on measurments, and used a 9x13. This was EXCELLENT! More "cake" than "brownie" but so tasty. I skipped the walnuts, but the topping was delicious. It's all I can do to not grab a square every time I'm near the kitchen :)

Perfect right out of the pan brownies! Not over chocolatey. If didn't know it was there, would never guess they have the zucchini in them. Will definitely make these again!
