Melt in your Mouth Zucchini Bread
This recipe is a melt-in-your-mouth type of bread. The key to making it is using the sourdough discard OR active sourdough starter. Both should have been souring for at least 24 hours before using. 12 hours is acceptable, but I find the better flavor happens when it has been souring for at least 24 hours.
I have even made this recipe with a cold sourdough starter! The process is the same. As long as it had been souring/fermenting for 24 hours before entering the refrigerator, you are golden to go ahead and use it!
How to Grate Zucchini?
The last step before mixing in your chocolate chips is to grate your zucchini and fold it in.
What is the best way to grate zucchini?
I tend to use my ninja blender, however, if you use a food processor or blender, you will need to press the water out of the zucchini before you fold it into the recipe.
Another easy way to grate zucchini is to simply grate it using a box grater. I like my kitchen aid grater because it comes with a sealable container that attaches to the bottom for mess-free grating!
Tools for this Recipe
You will need a few common kitchen tools for this recipe.
Blender or Box Grater
Mixer Bowl
Rubber Spatula
Bread Loaf Pan (8x4x2.5 inch) (my favorite are silicone)
Ingredients for the Sourdough Zucchini Bread
1 cup (125g), finely grated zucchini - yellow or green works
2 cups sourdough starter or sourdough discard (fermented for at least 24 hours)
2 tsp baking powder
1 tsp baking soda
½ tsp cinnamon
½ tsp salt
3 large eggs, room temperature
¾ cup Gentle Sweet
2 tbsp plain Greek yogurt
¾ cup stevia sweetened chocolate chips
Simple Instructions for the Sourdough Bread
Preheat the oven to 375°F.
In a small bowl, stir together the baking powder, baking soda, cinnamon, and salt; set aside.
In a large bowl, beat together eggs, Gentle Sweet, Greek Yogurt, and wet sourdough starter.
Fold in Zucchini and chocolate chips.
Add the flour mixture to the wet ingredients until combined. Do not overmix.
Use a rubber spatula to mix in chocolate chips.
Oil a 9"×5" inch loaf pan, then pour in batter.
Bake for 50-55 minutes.
Transfer to a cooling rack and cool before serving.
Storing Zucchini Bread
There are no perishables in this bread therefore you can store it on the countertop for 3-4 days. I like storing mine in my cake container on my countertop. After the 3-4 days I recommend placing it in the refrigerator.
You can freeze this bread. Wrap in plastic wrap and put in a freezer ziplock bag for up to 2 months. The bread does lose a bit of its structure, but the flavor will still be fine after thawing.
