How to make Zucchini Brownies
- Step 1: Shred your zucchini into a small bowl and set it aside. In a large bowl add the oil, sugar, and vanilla.
- Step 2: Mix the wet ingredients together.
- Step 3: In a small separate mixing bowl whisk the dry ingredients together.
- Step 4: Mix the flour mixture into the sugar and oil. The brownie batter will seem very dry and that's normal.
- Step 5: Fold in the shredded zucchini and let it rest for about 10 minutes and continue mixing.
- Step 6: Add in the chocolate chips and once it's all combined spread the brownie batter into a 9x13 prepared pan lined with parchment paper or sprayed with cooking spray.
- Use a cheese grater to shred your grated zucchini.
- Don't squeeze or drain your zucchini.
- The batter will seem dry, but the excess moisture from the zucchini will allow the batter to come together.
- Sprinkle some chopped walnuts on top for the best brownies.
How to store Zucchini Brownies
Store in an airtight container at room temperature for 4-5 days.
One good thing about an abundance of extra zucchini from your zucchini plant is all the baking you can do. In baking, zucchini does what applesauce or bananas will do. Zucchini has a mild flavor and generally contains a lot of water it's a great way to add moisture to baked goods and a boost of nutrition.
I like to use dark chocolate chips in this zucchini brownie recipe, but semi-sweet chocolate chips also work great. Or you could even toss in some peanut butter chips
The batter is supposed to be dry, then once you add in the zucchini let it rest for 8-10 minutes. The zucchini will release its moisture and helps the batter come together.
Yes, the cooled brownies can be cut into squares. The best way is to wrap each one in plastic wrap and place it in a ziplock freezer bag and freeze it for up to 2 months. Thaw at room temperature.
If your zucchini doesn't have a lot of water in it the brownies may turn out a bit dryer. You can add one tablespoon of water at a time for the batter to become wetter and come together.
I don't recommend leaving it out in this case, the brownies will turn out flat and not as thick as the recipe intended.
