- 1 ½ tsp baking soda
- 1 tsp salt
- ½ cup vegetable oil
- 1 ½ cups granulated sugar
- 2 tsp vanilla extract

How to Make Zucchini Brownies
- Preheat and Prep: Preheat your oven to 350°F. Line a 9×13-inch baking pan with foil and coat with non-stick spray.
- Mix Dry Ingredients: In a bowl, whisk together flour, cocoa powder, baking soda, and salt.
- Mix Wet Ingredients: In a mixer, beat together oil, sugar, and vanilla until well combined.
- Combine and Fold: Gradually add the dry ingredients to the wet mixture. Fold in the shredded zucchini.
- Rest the Batter: Let the mixture rest to absorb moisture. Add water one tablespoon at a time, just until the batter is thick but spreadable.
- Add Nuts (Optional): Fold in walnuts if using.
- Bake: Spread the batter evenly into the pan. Bake for 25–30 minutes or until brownies spring back when gently touched. Cool completely.
Frosting Time!
- Mix the Frosting: Whisk together melted butter, cocoa powder, and powdered sugar. Add milk, vanilla, and a pinch of salt. Mix until smooth.
- Frost and Chill: Spread over the cooled brownies. Chill to set before slicing into squares.
Tips for the Best Chocolate Zucchini Treat
- No need to peel. Zucchini skin is soft and disappears into the batter.
- Drain only if super juicy. Usually, you can add it right in.
- Resting is key. Letting the batter sit helps the flour and cocoa absorb the zucchini’s moisture.
- Frosting optional—but fabulous. These are great on their own, but the frosting takes them over the top.
How These Brownies Won Over My Veggie-Skeptics

Serve these brownies with a cold glass of milk or a scoop of vanilla ice cream for a true treat. Store in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. You can also freeze them (frosted or unfrosted) for up to 2 months. Just let them thaw in the fridge overnight.

Yes, use a 1:1 gluten-free flour blend.
Do I need to squeeze the zucchini?
Only if it’s overly watery, most of the time, can it go straight into the batter.
Can I skip the frosting?
Definitely! They’re still rich and chocolatey on their own.
