How to Make Secretly Healthy Zucchini Brownies
Step 1: Preheat & Prep
- Preheat oven to 350°F (175°C).
- Line an 8×8-inch baking pan with parchment paper or lightly grease it.
Step 2: Shred the Zucchini
- Finely shred unpeeled zucchini using a box grater.

In a large bowl, whisk together:
- Maple syrup (or honey)
- Applesauce
- Egg
- Vanilla extract
Stir in the shredded zucchini until well combined.
Step 4: Add Dry Ingredients

- Fold in chocolate chips or any mix-ins.
Step 5: Bake the Brownies

Frequently Asked Questions
Can I taste the zucchini?
Nope! When finely shredded and baked, zucchini becomes invisible. It simply adds moisture and nutrients.
Are these brownies keto?
Not exactly — they’re healthier but not keto. For a low-carb version, you’d need almond flour and a sugar substitute.
Can I double the recipe?
Yes! Bake in a 9×13-inch pan for 28–35 minutes. Keep an eye on the center for doneness.
Can I use cocoa powder or cacao powder?
Yes! Both work. Cacao is slightly more bitter but has more antioxidants.
