Ingredients for Chocolate Sourdough Zucchini Muffins
Gathering the right ingredients is the first step to creating these delightful Chocolate Sourdough Zucchini Muffins. Here’s what you’ll need:
- Sourdough Discard: This is the star of the show! It adds a unique tang and moisture to the muffins.
- Unsalted Butter: Melted butter brings richness and flavor. You can substitute it with coconut oil for a dairy-free option.
- Vegetable Oil: This keeps the muffins moist. Canola or sunflower oil works well too.
- Granulated Sugar: Sweetness is key! You can use brown sugar for a deeper flavor.
- Egg: This binds everything together and adds structure. For a vegan option, try a flax egg.
- Milk: It adds moisture and helps create a tender crumb. Almond or oat milk can be used as alternatives.
- Vanilla Extract: A splash of vanilla enhances the overall flavor. Pure vanilla is best, but imitation works too.
- All-Purpose Flour: This is the base of your muffins. Whole wheat flour can be a healthier substitute.
- Cocoa Powder: Unsweetened cocoa powder gives that rich chocolate flavor. Dutch-processed cocoa can be used for a smoother taste.
- Baking Powder and Baking Soda: These leavening agents help the muffins rise. Make sure they’re fresh for the best results.
- Salt: Just a pinch enhances all the flavors. Don’t skip it!
- Zucchini: Finely shredded, it adds moisture and sneaks in some veggies. You can use yellow squash as a substitute.
- Semi-Sweet Chocolate Chips: These add bursts of chocolatey goodness. Dark chocolate chips can be a delightful alternative.

How to Make Chocolate Sourdough Zucchini Muffins
Now that we have our ingredients ready, let’s dive into the fun part—making these Chocolate Sourdough Zucchini Muffins! Follow these simple steps, and you’ll have a batch of delicious muffins in no time.
Step 1: Preheat the Oven and Prepare the Muffin Tin
First things first, preheat your oven to 350°F (175°C). This step is crucial because it ensures even baking. While the oven warms up, line your muffin tin with paper liners. This makes for easy removal later and keeps your muffins looking pretty!
Step 2: Mix Wet Ingredients
In a large bowl, combine the sourdough discard, melted butter, vegetable oil, and granulated sugar. Use a whisk or a spatula to mix until everything is smooth and well combined. This mixture is the foundation of your muffins, so take your time to blend it well.
Step 3: Add Egg, Milk, and Vanilla
Next, crack in the egg, pour in the milk, and add the vanilla extract. Each of these ingredients plays a vital role. The egg binds everything together, while the milk adds moisture. The vanilla? It’s like a warm hug for your taste buds, enhancing the overall flavor!
Step 4: Combine Dry Ingredients
In another bowl, whisk together the all-purpose flour, cocoa powder, baking powder, baking soda, and salt. This step is important for even distribution of the leavening agents. You want your muffins to rise beautifully, so make sure there are no lumps!
Step 5: Mix Wet and Dry Ingredients
Now, it’s time to bring the wet and dry ingredients together. Gradually add the dry mixture to the wet mixture, stirring gently. Be careful not to overmix! A few lumps are okay. Overmixing can lead to dense muffins, and we want them light and fluffy.
Step 6: Fold in Zucchini and Chocolate Chips
Gently fold in the finely shredded zucchini and chocolate chips. This is where the magic happens! The zucchini adds moisture, while the chocolate chips provide delightful bursts of sweetness. Make sure they’re evenly distributed throughout the batter.
Step 7: Fill Muffin Cups
Using a spoon or an ice cream scoop, divide the batter evenly among the prepared muffin cups. Fill each cup about two-thirds full. This allows room for the muffins to rise without overflowing. Trust me, a little extra care here goes a long way!
Step 8: Bake to Perfection
Pop the muffin tin into the preheated oven and bake for 20-25 minutes. To check for doneness, insert a toothpick into the center of a muffin. If it comes out clean or with a few crumbs, they’re ready! Let the muffins cool in the pan for a few minutes before transferring them to a wire rack. Cooling them properly helps maintain their texture.
