- ½ teaspoon of baking soda
- 1 teaspoon of vanilla extract
- A pinch of salt
Step-by-Step Instructions
- Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×9-inch baking pan or line it with parchment paper for easy removal later.

What to Serve Fudgy Sourdough Zucchini Brownies With
These brownies are delicious on their own, but they pair wonderfully with a dollop of whipped cream or a scoop of vanilla ice cream for a delightful dessert experience. If you want to create a more personalized touch, consider serving them alongside a fresh fruit salad or a cup of coffee to balance out the sweetness.
Top Tips for Perfecting Fudgy Sourdough Zucchini Brownies
- Grate the Zucchini Well: Make sure to grate the zucchini finely, as this helps it blend seamlessly into the batter without compromising the texture.
- Use Day-Old Sourdough: A sourdough starter that’s been sitting for a day or two can add an even richer flavor to your brownies.
- Don’t Overmix: When combining wet and dry ingredients, be gentle. Overmixing can lead to tougher brownies.
- Experiment with Add-Ins: Chocolate chips, nuts, or a sprinkle of cinnamon can elevate the flavor profile!
Storing and Reheating Tips
To store leftover Fudgy Sourdough Zucchini Brownies, place them in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate them for up to a week or freeze them for up to 3 months.
