In another bowl:
1. Mix together the flour, 1/2 cup cocoa powder, baking soda, and salt.

How to Perfect Zucchini Brownies
To ensure your zucchini brownies turn out perfectly every time, follow these simple tips for baking success.
- Use fresh zucchini: Freshly grated zucchini keeps moisture and flavor intact, making your brownies more delicious.
- Don’t over-mix: Mixing just until combined prevents tough brownies. Over-mixing develops gluten in the flour.
- Check doneness carefully: Use a toothpick inserted into the center; it should come out clean or with a few crumbs for fudgy brownies.
- Cool before frosting: Letting your brownies cool fully prevents the frosting from melting and ensures beautiful presentation.
- Experiment with sweeteners: Try using coconut sugar or maple syrup for healthier alternatives to white sugar.

Common Mistakes to Avoid
When making Zucchini Brownies, it’s easy to slip up. Here are some common mistakes to watch for.
- Using Too Much Zucchini: Adding too much zucchini can make the brownies overly moist. Stick to the recommended amount for the best texture.
- Not Squeezing Out Excess Moisture: If your zucchini is wet, be sure to squeeze out extra moisture with paper towels. This prevents a soggy brownie.
- Skipping the Frosting: The frosting adds a delightful richness. Don’t skip it; it completes the dessert and enhances flavor.
- Overbaking the Brownies: Overbaking can lead to dry brownies. Check them around 25 minutes and remove them when they spring back gently.
- Using Cold Ingredients: Cold ingredients can affect how well your batter combines. Allow eggs and milk to come to room temperature before mixing.
