Zucchini Brownies
When I first made these Zucchini Brownies in 2012 I declared that I would never need another brownie recipe. They are the BEST brownie I have ever eaten, hands down. But, zucchini is very much a seasonal product, so having a great brownie recipe that doesn’t have zucchini is important. Every summer I am reminded just how magical zucchini is in baked goods and these become my favorite again!
The Secret to Baking with Zucchini
Size matters. A large zucchini will be drier. A small zucchini with have more moisture. Certain recipes work best with different sizes. For instance, I tend to use a medium to small with this recipe because I want the moisture the zucchini brings, but I use a large zucchini for my Double Chocolate Zucchini Cupcakes.
Use the fine side of your grater. Coarser pieces will have a slightly more noticeable flavor and texture in a finished cake or bread recipe. (Farm kids tend to want that!)
Some recipes ask that the zucchini is pressed well with a clean towel to soak up excess moisture or to prevent whatever your baking from getting too soggy. Pay close attention to the recipe that you are making with zucchini as the level of moisture they provide is important. For instance, in this recipe, the zucchini is the main source of moisture and should NOT be drained!
Double Chocolate Zucchini Brownies
This recipe is going to test any experienced bakers boundaries as it does not act like a normal brownie.
The batter is DRY. Extremely dry. Until you add the zucchini that is! Assemble the batter according to the recipe instructions and then let it rest for 5 minutes. Stir again and you will see how much moisture the zucchini adds!
I added semi-sweet chocolate chunks to this batch to make the double chocolate. You can add milk chocolate chips, peanut butter chips, white chocolate chips, or no chips! They are so good and so rich the extra flavor is not necessary. (But can be fun!) If you do use chocolate morsels instead of chunks, be sure to use 1 1/2 cups instead of 1 1/4. Reserve a few for the top too!
As you can see, the zucchini bits practically disappear into the glorious chocolate layers. If you don’t tell people, they will never know you added a full 3 cups of this abundant vegetable!

Oh my goodness! I have been coming back to this recipe over and over to only JUST NOW realize that this is Amanda’s recipe 😅 I’ve been following her on Instagram for about 3 years now! No wonder these brownies are AMAZING – all her recipes are!
These bake up so delicious! It’s my go to brownie recipe, especially in the summer when I’ve all those zucchini in my garden. Right now, my pregnant coworker is craving them. Her wish is my command.
Super tasty! I changed the recipe a bit, I substituted baking powder for baking soda using a 3:1 ratio. I also added mini chocolate chips to the batter and used an 8×8 pan.
Doesn’t really taste like zucchini. I think mine was more present because I didn’t finely grate everything- left a few large chunks in there. For consistency, it’s more cake like instead of a dense brownie.
This is a really good and recipe.
These are Absolutely Delicious!! I just watched the video and see that they sift the flour and cocoa. It doesn’t mention this in the recipe! I’m trying them with almond flour this time and hope they work out!
