Recommended Products for This Recipe
These are a few products I personally use and recommend for getting the best results with this recipe.
None of these are required, but they make the process smoother and the final loaf even better.
1. USA Pan Aluminized Steel Loaf Pan
This pan heats evenly so the loaf bakes through without a burnt bottom or a raw center. The nonstick coating also means the bread releases cleanly every single time.
2. OXO Good Grips Box Grater
Shredding zucchini quickly and evenly matters for texture, and this grater makes quick work of it. The wide base and non slip grip keep it steady while you shred.
3. Natural Creamy Peanut Butter
A good quality creamy peanut butter without added sugar makes a big difference in flavor.
I always stick to smooth peanut butter here since crunchy versions can make the crumb uneven.
4. Ghirardelli Semi Sweet Chocolate Chips
These chips melt into soft, rich pockets throughout the loaf instead of turning waxy. They also hold their shape nicely if you sprinkle extra on top before baking.
5. Raw Wildflower Honey
A good raw honey adds moisture and a subtle floral sweetness that pairs perfectly with the peanut butter.
It is also less processed than standard clover honey, which gives the loaf a deeper flavor.
This same combination of pantry staples and a few specialty picks shows up often in my Chocolate Chip Banana Bread Recipe as well.
Step-by-Step Instructions: How to Make Peanut Butter Chocolate Chip Zucchini Bread
1. Prep the pan and oven
- Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
- Grease a 9×5 inch loaf pan with nonstick spray or butter.
- Line the bottom of the pan with a strip of parchment paper for easy removal later.
2. Shred the zucchini
- Wash one medium zucchini and trim off both ends.
- Shred the zucchini using a box grater, skin and all.
- Measure out 1 and 1/2 cups of shredded zucchini and set it aside. Do not squeeze out the moisture, since that moisture is what keeps the bread soft.
3. Mix the dry ingredients
- In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, and ground cinnamon.
- Make sure the leavening agents are evenly distributed so the loaf rises properly.
- Set the dry mixture aside while you prepare the wet ingredients.
4. Mix the wet ingredients
- In a separate large bowl, whisk together the vegetable oil, creamy peanut butter, brown sugar, and honey until smooth.
- Add the eggs one at a time, whisking well after each addition.
- Whisk in the milk and vanilla extract until the mixture looks glossy and well combined.
5. Combine the batter
- Pour the dry ingredients into the bowl with the wet ingredients.
- Stir gently with a rubber spatula until just combined. A few streaks of flour are fine at this stage.
- Do not overmix, since overmixing can make the loaf dense instead of tender.
6. Fold in the zucchini and chocolate chips
- Add the shredded zucchini to the batter and fold it in gently.
- Add the chocolate chips and fold until they are evenly distributed throughout the batter.
- Stop folding as soon as everything is combined to keep the batter light.
7. Bake the loaf
- Pour the batter into the prepared loaf pan and smooth the top with a spatula.
- Sprinkle a few extra chocolate chips on top if you want a bakery style finish.
- Bake for 55 to 65 minutes, tenting the top loosely with foil after 30 minutes if it is browning too quickly.
- The loaf is done when a toothpick inserted into the center comes out clean or with a few moist crumbs.
8. Cool and slice
- Let the loaf cool in the pan for 15 minutes.
- Use the parchment paper to lift the loaf out and transfer it to a wire cooling rack.
- Allow the bread to cool completely before slicing for the cleanest cuts.

Tips for The Best Peanut Butter Chocolate Chip Zucchini Bread
A few small details make a big difference in how this loaf turns out. Keep these tips in mind as you bake.
- Do not peel the zucchini. The skin is completely undetectable once baked and adds extra nutrients.
- Use creamy peanut butter rather than crunchy for a smoother, more tender crumb.
- Measure your flour by spooning it into the measuring cup and leveling it off, rather than scooping directly from the bag.
- Let the bread rest overnight before slicing for the best texture, if you can wait that long.
- Check for doneness a few minutes early, since ovens can vary and this bread is easy to overbake.
This same technique of resting overnight also improves the texture of this Sour Cream Banana Bread Recipe.
Serving Suggestions
This loaf is versatile enough to serve any time of day. Here are a few of my favorite ways to enjoy it.
- Warm with a pat of butter melting into each slice
- Toasted and spread with extra peanut butter for breakfast
- Alongside a cup of coffee or tea for an afternoon break
- With a drizzle of honey and a sprinkle of flaky sea salt
- Paired with fresh berries for a lighter dessert plate

- Swirl a few tablespoons of extra peanut butter on top of the batter before baking

FAQs About Peanut Butter Chocolate Chip Zucchini Bread
1. Do I need to peel the zucchini before shredding it?
No, peeling is not necessary. The skin blends completely into the batter and adds extra fiber and nutrients without changing the taste or texture.
2. Can I use natural peanut butter instead of regular creamy peanut butter?
Yes, but stir it very well first so the oil is fully incorporated. If your natural peanut butter is on the runnier side, the loaf may bake up slightly denser.
3. Why is my zucchini bread too dense or gummy?
This usually happens from overmixing the batter or packing the zucchini too tightly when measuring. Stir just until the ingredients are combined and measure the zucchini loosely.
4. Can I turn this recipe into muffins?
Yes, this batter works well as muffins. Divide it into a lined muffin tin and bake at 350 degrees Fahrenheit for 18 to 22 minutes, or until a toothpick comes out clean.
5. How do I know when the loaf is fully baked?
Insert a toothpick into the center of the loaf. It is done when the toothpick comes out clean or with just a few moist crumbs attached, with no wet batter.

Nutrition
Notes
- Zucchini: Do not peel the zucchini—the skin blends completely into the batter and adds extra nutrients.
- Peanut butter: Use creamy peanut butter rather than crunchy for a smoother, more tender crumb. Natural peanut butter works if stirred very well first, but the loaf may be slightly denser.
- Flour measurement: Measure flour by spooning it into the measuring cup and leveling it off with a knife, not by scooping directly from the bag, to avoid a dry loaf.
- Do not overmix: Stir just until the ingredients are combined to keep the loaf tender and light. Overmixing develops gluten and makes the bread dense.
- Moisture is key: Do not squeeze out the zucchini’s moisture—that liquid is what keeps the bread soft and tender.
- Rest overnight: For the best texture, let the bread cool completely and rest overnight before slicing, if you can wait that long.
- Check early: Ovens can vary, so start checking for doneness a few minutes early to avoid overbaking.
- Storage: Store in an airtight container at room temperature for up to 4 days, refrigerate for up to 1 week, or freeze individual slices wrapped in plastic wrap for up to 3 months.
- Variations: Swap chocolate chips for peanut butter chips, add 1/2 cup of chopped walnuts or pecans, or use almond or sunflower seed butter for a nut-free option.
- Muffin version: Turn this into muffins by baking in a lined muffin tin at 350°F for 18-22 minutes.
