Sourdough Chocolate Zucchini Bread

Sourdough chocolate zucchini bread is a moist and delicious quick bread that our whole family loves! We make a lot of it at the end of summer when we harvest lots of zucchini from the garden. This sourdough chocolate zucchini bread makes the perfect summer breakfast, quick dessert or snack. A lot of folks complain about too much zucchini and wonder what to do with it, but with zucchini recipes like this around, we can never have too much zucchini. This recipe can easily be made into zucchini muffins that are perfect for packing in lunches or taking with you on the go.
I always try to make sure that I preserve some extra zucchini so I can make this recipe all throughout the winter. My favorite way to preserve zucchini is to shred it in the food processor and then freeze it in a freezer bag. Then it can easily be thawed out and made into this delicious zucchini bread.
We like to make different flavors of this moist quick bread including lemon poppy seed zucchini bread, and classic zucchini bread. Be sure to look for those recipes here on our blog.

To make sourdough zucchini bread:
Grease and flour the pan by spreading some butter or some kind of fat in the pan. Add a little bit of flour and shake it around until the inside of the pan is completely coated. You could also line the pan with parchment paper.

Pour the batter into the prepared pan.

Bake at 350 degrees in a preheated oven for 1 hour or until knife inserted in the center of your bread comes out clean. I often end up baking this bread for closer to 1 hour and 25 minutes. Every oven will vary slightly.
To make sourdough zucchini muffins:
Line each muffin cup with a paper liner. Use an ice cream scoop to spoon the batter into each muffin cup.

Bake at 350 degrees for 25 minutes or until a knife inserted in the center of a muffin comes out clean.
For best results, allow to cool completely on a wire rack before storing in an airtight container in the refrigerator.
Serve with fresh butter or cream cheese.
Best if eaten within 3-5 days, or store in the freezer for an easy breakfast or dessert later on. To thaw, allow to sit out for a few hours at room temperature.

Tips
- This bread can be mixed up the night before and allowed to sit out at room temperature to long ferment which increases the health benefits and digestibility
- A great way to use up leftover sourdough starter discard. You can also use active sourdough starter if you don’t have any discard in your refrigerator
- If you’re looking for a more natural sweetener, try this cane sugar from Azure Standard.
- You can use any kind of fat – oil, melted butter, beef tallow, coconut oil, or if you want to make these oil-free you can substitute applesauce for the oil
- If you have extra chocolate chips, it makes the bread even more gooey and delicious, but it’s honestly just as good without them too.

Equipment
- 1 Stand mixer or a large mixing bowl my absolute favorite stand mixer is a bosch mixer. I’ve used it almost everyday for years and it has served me so well including in the summertime when we bake almost 100 loaves of bread for farmers' market each week. I know several people that have had bosch mixers for over 30 years and they are still running strong. Getting a bosch mixer is one of the best investments you can make for your kitchen. Get an extra $20 off when ordering from nutrimill.com/wagonwheel.
- 1 Cookie Paddles If you get the bosch mixer, I highly recommend you get the cookie paddles which is what I use for making this quick bread. You will need the metal top for the cookie paddles. I also highly recommend getting the cake paddles as well. I use all of them all the time. If you don’t have a stand mixer, you could use a large bowl and a hand mixer or large wooden spoon.
- 1 Loaf Pan I love my enamel cast iron bread pan from Nutrimill, but if I make more than one loaf, than I often use my regular bread pans as well.
- 1 Muffin tin, optional I really like this 24 cup tin, it allows me to make a bunch of muffins all at once. If you don’t have a muffin tin, just set your paper muffin liners inside narrow-mouth rings (like you would use for canning) and place them on a parchment-lined baking sheet. This will keep the muffin liners upright until the muffins are baked.
