Ingredients You Need

Here is everything you need for this Peanut Butter Chocolate Chip Zucchini Bread Recipe. I include some handy swaps so you can use what you already have in your pantry.

Dry ingredients

1 1/2 cups all-purpose flour
- Use unbleached if possible for better flavor.
- You can swap up to half with white whole wheat flour for a heartier loaf.
1 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon fine sea salt
1 teaspoon ground cinnamon
- Cinnamon pairs nicely with peanut butter and chocolate without overpowering them.

Wet ingredients

2 large eggs, room temperature
1/2 cup creamy peanut butter
- Use shelf stable peanut butter like Jif or Skippy for best texture.
- Natural peanut butter works, but stir it very well and pack it tightly in the measuring cup.
1/2 cup neutral oil
- Use canola, vegetable, or avocado oil.
- Oil keeps the bread extra moist compared to butter.
3/4 cup light brown sugar, packed
- Brown sugar adds moisture and a slight caramel note.
1/4 cup granulated sugar
- This balances sweetness and structure.
2 teaspoons vanilla extract

Zucchini and mix-ins

1 1/2 cups grated zucchini, lightly packed
- Do not peel the zucchini; the skin adds color and nutrients.
- Use small to medium zucchini for the best texture.
1 cup semisweet chocolate chips
- Use mini chips if you want more even chocolate distribution.
- Dark chocolate chips also taste great if you prefer less sweetness.
Optional: 1/2 cup chopped roasted peanuts
- Adds crunch and extra peanut flavor.

Equipment list

9 x 5 inch loaf pan
Large mixing bowl
Medium mixing bowl
Whisk
Rubber spatula or wooden spoon
Box grater for the zucchini
Measuring cups and spoons
Cooling rack
Parchment paper (helps lift the loaf out easily, but you can also grease and flour the pan)

Tips & Mistakes

Squeeze the zucchini gently, not aggressively, so it still holds some moisture and keeps the bread soft.
Measure flour by spooning it into the cup and leveling it, since packed flour makes the loaf dry.
Use room temperature eggs so they mix smoothly with the peanut butter and oil.
Stir natural peanut butter very well; streaky peanut butter causes greasy pockets.
Mix the batter until the flour just disappears; overmixing toughens the bread.
Fold chocolate chips in by hand so they do not sink or break.
Line the pan with parchment and leave a little overhang to lift the bread out easily.
Check doneness early; ovens vary and overbaking dries the loaf.
Let the bread cool at least 20 to 30 minutes before slicing so it holds its shape.
Store the loaf tightly wrapped; air exposure makes the edges stale quickly.

How to Make Peanut Butter Chocolate Chip Zucchini Bread Recipe

Step 1: Prep the pan and oven

Preheat your oven to 350°F. Grease a 9 x 5 inch loaf pan and line it with a parchment sling so you can lift the bread out later. Lightly grease the parchment as well so nothing sticks.

Step 2: Prep the zucchini

Wash the zucchini and trim off the ends. Grate it on the medium holes of a box grater. Gather the grated zucchini in your hands or in a clean kitchen towel and squeeze gently over the sink to remove excess water, then set it aside.

Step 3: Mix the dry ingredients

In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon. Break up any clumps of baking soda or flour. Set this bowl aside.

Step 4: Mix the wet ingredients

In a large mixing bowl, whisk the eggs until they look slightly frothy. Add the peanut butter, oil, brown sugar, granulated sugar, and vanilla. Whisk until the mixture looks smooth and glossy, with no streaks of peanut butter.

Step 5: Combine wet and dry

Add the dry ingredients to the wet ingredients in two additions. Stir gently with a spatula just until the flour almost disappears. You should still see a few light streaks of flour at this point.

Step 6: Fold in zucchini and chocolate chips

Add the grated zucchini and chocolate chips to the bowl. If you use chopped peanuts, add them now. Fold everything together until the zucchini and chips spread evenly through the batter and no dry flour remains.

Step 7: Fill the pan and bake

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 look. Bake for 50 to 60 minutes, until a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.

Step 8: Cool and slice

Place the pan on a cooling rack and let the bread cool in the pan for about 15 minutes. Use the parchment sling to lift the loaf out of the pan and set it directly on the rack. Cool at least another 15 to 20 minutes, then slice with a sharp serrated knife.

Variations I’ve Tried

I swap half the peanut butter with almond butter when I want a slightly lighter, nutty flavor. I also tried a version with dark chocolate chips and a tablespoon of espresso powder, which gave the bread a mocha vibe that tasted amazing with coffee. Sometimes I add 1/2 cup of rolled oats and reduce the flour by the same amount for a slightly chewier texture.

I tested a version with honey instead of some of the sugar and loved the subtle floral sweetness, though the loaf browned a bit faster. I also tried mini loaves and muffins; they baked in about 18 to 22 minutes and worked great for lunchboxes.

How to Serve Peanut Butter Chocolate Chip Zucchini Bread Recipe

Serve slices slightly warm with a smear of extra peanut butter on top for a double peanut hit. Pair it with cold milk, hot coffee, or your favorite tea for breakfast or an afternoon snack. Kids love it in lunchboxes, and you can pack individual slices in reusable containers.

You can also toast a slice lightly and top it with a little butter or a spoonful of Greek yogurt and berries. The bread works nicely as a dessert with a scoop of vanilla ice cream on the side.

How to store

Room temperature: Wrap the cooled loaf tightly in plastic wrap or store slices in an airtight container; keep it at room temperature for up to 3 days.
Fridge: Store in an airtight container in the refrigerator for up to 6 days; bring slices to room temperature or warm them slightly before serving.
Freezer: Wrap individual slices or the whole loaf in plastic wrap, then place in a freezer bag; freeze for up to 3 months.
Reheating: Warm slices in the microwave for 10 to 15 seconds or in a 300°F oven for about 5 to 8 minutes until soft and slightly warm.
