Zucchini Brownies Recipe

If you have an abundance of zucchini this recipe for zucchini brownies might be exactly what you are looking for. Not only are these brownies a way to put that zucchini to good use, but they are also some of the best brownies I have had in a while. The brownies are so moist you might even have to eat them with a fork. To top things off, they are covered in a delicious chocolate frosting. When you are making the batter you will notice it is extremely dry, almost to the point where it’s like crumbs. This is normal and once it starts baking in the oven, the moisture from the zucchini will come out and moisten it. These are so easy to make and delicious, it’s well worth giving them a try. Enjoy.

    I added two large eggs to the (already great) recipie and it made them more like cake (fluffy).

    thanks for all you do!

    These brownies were pretty good but not amazing. I don’t regret making them, but I am not sure if I would go out of my way to make them again.

  3. Karla says:

    Is the icing recipe right? It is very runny and alot of it!!! I am only using half and will only use half of the milk next time. I also added more powdered sugar to make it not quite as runny.

  4. Nadalein says:

    Why did mind turn cake like and spongy? What caused this? Over mixing? They weren’t dry but they weren’t moist and so not like brownies! It is a cake! What did I do wrong!

  5. Bobby says:

    Nadalein – I am not sure exactly why they would turn out like that. These brownies are a lot like a cake but when I made them they were super moist.

  6. Megan says:

    Hey bobby,
    I noticed for the frosting you require margarine. Could I use butter instead or will it make a difference?

  7. Bobby says:

    Megan – I have never tried using butter instead of margarine in this recipe, but I think it would work. If you do try it, please let everyone know how it turns out. Thanks.

  8. Megan says:

    bobby, my brownies turned out fab! I would almost prefer to call them zucchini cake brownies b/c the texture of the brownie is a very moist cake like brownie but not dry at all! Everyone loved them and for the frosting, I did use butter but only 1/4 cup of milk. the frosting turned out perfect with the 1/4 cup of milk and real butter instead of margarine!

    These are some of my favorite brownies that I’ve made occasionally over the past couple of years. I was surprised to see it here, as I have taken it from allrecipes.com before.
