Peanut Butter Chocolate Chip Zucchini Bread Recipe tastes like a cross between a soft peanut butter cookie and a moist chocolate chip muffin, with just enough zucchini to keep everything extra tender. It works perfectly for busy families, meal-preppers, or anyone who wants a cozy quick bread on the table in about 1 hour from start to finish. I tested this version so many times that my neighbors started “checking on me” right around the cooling rack.

Why Peanut Butter Chocolate Chip Zucchini Bread Recipe Is Worth It

This bread packs big peanut butter flavor, melty chocolate pockets, and a super soft crumb that stays moist for days. The zucchini disappears into the batter, so even veggie skeptics usually ask for a second slice.

You mix everything in one bowl, and the recipe uses basic pantry ingredients like peanut butter, brown sugar, and chocolate chips. It works as breakfast, snack, or dessert, so you get a lot of mileage from one loaf.

Ingredients You Need

Dry ingredients

1 ½ cups (180 g) all-purpose flour
½ cup (50 g) old-fashioned oats, lightly blended or left whole
1 teaspoon baking soda
½ teaspoon baking powder
½ teaspoon fine sea salt
1 teaspoon ground cinnamon
¼ teaspoon ground nutmeg (optional, but it adds cozy flavor)

Wet ingredients

2 large eggs, room temperature
½ cup (120 ml) neutral oil (canola, avocado, or light olive oil)
½ cup (130 g) creamy peanut butter (use shelf-stable; natural peanut butter works if you stir it very smooth)
½ cup (100 g) packed light brown sugar
¼ cup (50 g) granulated sugar
⅓ cup (80 ml) milk (dairy or unsweetened almond/oat milk)
2 teaspoons vanilla extract

Zucchini and mix-ins

1 ½ cups packed grated zucchini (about 1 medium zucchini), moisture squeezed out
¾–1 cup chocolate chips (semi-sweet or dark; mini chips spread more evenly)
¼ cup chopped roasted peanuts or walnuts (optional, for crunch)

Pantry shortcuts and notes

Use pre-shredded zucchini from the produce section if you feel short on time, but squeeze it extra well since it often holds more water.
Use chocolate chips from any brand you like; I often use Ghirardelli or Trader Joe’s because they melt nicely.
Swap half the peanut butter with almond butter if you want a slightly milder peanut flavor.

Equipment

9×5-inch loaf pan (metal pan browns more evenly than glass)
Large mixing bowl and whisk
Rubber spatula or wooden spoon
Box grater or food processor with shredding disc for the zucchini
Measuring cups and spoons
Cooling rack
Parchment paper (helps lift the loaf out cleanly)

Quick Tips & substitutions

Squeeze the zucchini over a clean kitchen towel until it feels damp but not dripping, or the bread can turn gummy.
Use room-temperature eggs so they mix smoothly with the peanut butter and oil.
Stir the batter gently and stop as soon as no dry streaks of flour remain to keep the crumb tender.
Toss chocolate chips with a teaspoon of flour before you add them so they stay more evenly distributed.
Swap all-purpose flour with a 1:1 gluten-free baking blend if you need a gluten-free version.
Use natural peanut butter only if you stir the jar very well; runny oil pockets can make the loaf dense.
Replace milk with any unsweetened non-dairy milk if you want a dairy-free loaf (check chocolate chips for dairy).
Use mini chocolate chips if you want chocolate in every bite without overwhelming the peanut butter flavor.

How to Make Peanut Butter Chocolate Chip Zucchini Bread Recipe

Step 1: Prep the pan and oven

Preheat the oven to 350°F (175°C). Line a 9×5-inch loaf pan with parchment paper and lightly grease the sides so the bread releases easily. Set the pan aside while you mix the batter.

Step 2: Grate and drain the zucchini

Wash and dry the zucchini, then trim the ends. Grate it on the medium holes of a box grater or use a food processor with a shredding disc. Wrap the grated zucchini in a clean kitchen towel or paper towels and squeeze out as much liquid as you can, then fluff it with your fingers and set it aside.

Step 3: Mix the wet ingredients

In a large mixing bowl, whisk the eggs until smooth. Add the oil, peanut butter, brown sugar, granulated sugar, milk, and vanilla. Whisk until the mixture looks thick, glossy, and fully combined with no streaks of peanut butter.

Step 4: Add the dry ingredients

Sprinkle the flour, oats, baking soda, baking powder, salt, cinnamon, and nutmeg over the wet mixture. Use a spatula to fold everything together gently. Stop mixing as soon as you no longer see dry flour; a few small lumps in the batter work just fine.

Step 5: Fold in zucchini and chocolate chips

Add the squeezed zucchini and most of the chocolate chips to the bowl, along with nuts if you use them. Fold them in with a spatula until they spread evenly through the batter. The batter will look thick but scoopable.

Step 6: Fill the pan

Scoop the batter into the prepared loaf pan and smooth the top with a spatula. Sprinkle the remaining chocolate chips and a few extra oats or chopped nuts on top if you want a bakery-style look. Gently tap the pan on the counter to release any large air bubbles.

Step 7: Bake

Place the pan on the middle rack of the oven. Bake 50–60 minutes, until a toothpick inserted in the center comes out mostly clean with just a few moist crumbs and maybe a bit of melted chocolate. If the top browns too quickly, tent the loaf loosely with foil during the last 10–15 minutes.

Step 8: Cool

Set the pan on a cooling rack and let the bread cool in the pan for about 15 minutes. Lift the loaf out using the parchment and transfer it directly to the rack. Let it cool at least another 30–45 minutes before slicing so it holds together and the chocolate sets slightly.

Step 9: Slice and serve

Use a sharp serrated knife to cut the bread into thick slices. Wipe the knife between cuts if the chocolate sticks. Serve warm or at room temperature, and enjoy that peanut butter chocolate chip goodness with your favorite drink.

Recipe Variations

Gluten-free: Use a 1:1 gluten-free baking flour and certified gluten-free oats.
Vegan: Replace eggs with two flax eggs (2 tablespoons ground flax + 5 tablespoons water) and use non-dairy milk and vegan chocolate chips.
Low sugar: Cut the brown sugar to ⅓ cup and use 70% dark chocolate; the bread stays sweet but less dessert-like.
Low carb-ish: Use an almond flour baking blend and a granulated sugar substitute that measures like sugar, and skip the oats.
Nut-free: Swap peanut butter with sunflower seed butter and use nut-free chocolate chips.
Extra protein: Stir in 1–2 scoops of unflavored or vanilla protein powder and reduce flour by about ¼ cup.
Add-ins: Mix in shredded coconut, chopped dates, or a swirl of extra peanut butter on top before baking.

Ways to Serve Peanut Butter Chocolate Chip Zucchini Bread Recipe

Warm a slice and top it with a thin smear of peanut butter or almond butter.
Serve it with Greek yogurt and berries for a more filling breakfast.
Pack slices in lunchboxes as a sweet-but-not-cupcake treat.
Toast leftover slices in a skillet with a little butter for a crisp edge and soft center.
Cut into cubes and mix with vanilla yogurt and fruit for a quick parfait.

Storage Success

Let the Peanut Butter Chocolate Chip Zucchini Bread cool completely before you store it, or condensation can make the crust soggy. Keep it at room temperature in an airtight container for up to 3 days, and place a paper towel above and below the loaf to catch extra moisture. For longer storage, wrap slices individually and freeze them for up to 3 months, then thaw on the counter or warm them in the microwave. I keep a stash in the freezer so future me always has a peanut butter chocolate snack within reach.
