These zucchini brownies are SO GOOD!

zucchini brownies the southern lady cooks


Zucchini Brownies are a great way to use up some of that zucchini from the garden.  I have one zucchini plant this summer and it is half as big as my patio and I get two or three zucchini a day! I cannot believe this plant has produced so much.  I have made zucchini bread, fried zucchini, zucchini cake, zucchini brownies and I guess the cookies will be next on the menu. We love zucchini and these brownies are one of our favorites. This makes a moist, chewy zucchini brownie with lots of chocolate flavor.

Ingredients Needed for Zucchini brownies:

All-purpose flour

100% pure cocoa

Baking soda


White granulated sugar

Shredded zucchini

Sour cream

Butter, melted


Vanilla extract

Chocolate chips (I used semi-sweet)

Chopped walnuts or pecans

If you have an abundance of zucchini, you may want to try our Italian zucchini pasta casserole. It’s SO good!
