Ingredients You’ll Need

Dry ingredients

1 ½ cups all purpose flour
- Use a standard unbleached flour like King Arthur or Gold Medal.
- Whole wheat pastry flour also works, but the loaf turns slightly denser.
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 creamy peanut butter
- Use shelf stable peanut butter like Skippy or Jif for the best texture.
- Natural peanut butter works, but stir it very well so no oil pockets remain.
½ cup neutral oil
- Use canola, vegetable, or light olive oil.
- You can swap half the oil with unsweetened applesauce for a lighter loaf.
¾ cup packed light brown sugar
- Coconut sugar also works and adds a deeper caramel note.
¼ cup granulated sugar
2 teaspoons vanilla extract

Zucchini and mix ins

1 ½ cups grated zucchini, lightly packed
- Use about 1 medium zucchini.
- Do not peel it; the green flecks look pretty and stay tender.
¾ to 1 cup semi sweet chocolate chips
- Mini chips spread more evenly in each slice.
- Use dairy free chocolate chips if you need a dairy free loaf.
¼ cup chopped roasted peanuts (optional, for crunch on top or inside)

Equipment

9 x 5 inch loaf pan
- Metal pans brown more evenly than glass.
Large mixing bowl
Medium mixing bowl
Whisk
Rubber spatula or wooden spoon
Box grater for zucchini
Measuring cups and spoons
Cooling rack
Parchment paper (helps with easy removal, but you can grease the pan well instead)

Tips & Tricks

Squeeze the zucchini gently in a clean kitchen towel if it feels very wet, but keep some moisture so the bread stays soft.
Pack the grated zucchini lightly in the measuring cup so you avoid a soggy center.
Use room temperature eggs so they mix smoothly with the peanut butter and oil.
Stir the batter just until the flour disappears to keep the crumb tender.
Toss chocolate chips with a teaspoon of flour before folding them in so they stay evenly distributed.
Line the loaf pan with parchment and leave a little overhang so you lift the bread out easily.
Check doneness with a toothpick in the center; a few moist crumbs count as done, but wet batter needs more time.
Let the bread cool at least 20 to 30 minutes before slicing so it holds its shape.
Slice with a serrated knife in a gentle sawing motion to avoid squishing the loaf.
Double the recipe and bake two loaves if your oven fits them; you freeze one for later and save yourself work.

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 with oil or nonstick spray, then line it with parchment paper so it hangs over the long sides. This setup lets you lift the loaf out easily once it cools.

Step 2: Grate and prep the zucchini

Wash and dry the zucchini, then trim off the ends. Grate it on the medium holes of a box grater. Lightly gather the grated zucchini in your hands or a towel and squeeze once or twice to remove excess water, but stop before it feels dry.

Step 3: Mix the dry ingredients

In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg. Break up any little clumps of flour or spice so the mixture looks even. Set this bowl aside.

Step 4: Mix the wet ingredients

In a large 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 and the peanut butter fully blends in.

Step 5: Add zucchini and chocolate chips

Fold the grated zucchini into the wet mixture with a spatula. Sprinkle the chocolate chips over the top, along with chopped peanuts if you use them. Gently fold until everything spreads evenly through the batter.

Step 6: Combine wet and dry

Pour the dry ingredient mixture over the wet mixture. Use a spatula to fold the batter together with slow, sweeping motions. Stop mixing as soon as you no longer see streaks of dry flour, since extra stirring can toughen the bread.

Step 7: Fill the pan and top

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

Step 8: Bake

Place the pan on the middle rack of your oven. Bake for 50 to 60 minutes, depending on your oven and pan. Start checking at 45 minutes and test the center with a toothpick; it should come out mostly clean with just a few moist crumbs.

Step 9: 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 overhang and place it directly on the rack. Cool at least another 15 minutes before slicing so the chocolate sets slightly and the slices hold together.

Step 10: Slice and serve

Use a serrated knife to cut the bread into thick slices. Wipe the knife between cuts if warm chocolate sticks to it. Serve warm, at room temperature, or lightly toasted, depending on your mood and patience level.

What to Serve with Peanut Butter Chocolate Chip Zucchini Bread Recipe

This Peanut Butter Chocolate Chip Zucchini Bread Recipe pairs beautifully with a cold glass of milk, almond milk, or oat milk. You can also serve it with hot coffee, chai, or a simple black tea for a cozy afternoon break. Kids usually love a slice with sliced bananas or apple wedges on the side. For a more filling breakfast, add Greek yogurt and a handful of fresh berries.

Storage Options

Store leftover zucchini bread at room temperature in an airtight container for up to 3 days; place a paper towel under and over the slices to catch extra moisture.
Keep the bread in the fridge for up to 1 week; wrap it tightly in plastic or store it in a sealed container to prevent it from drying out.
Freeze individual slices or the whole loaf for up to 3 months; wrap in plastic, then place in a freezer bag and label with the date.
Reheat slices in the microwave for 10 to 20 seconds or in a 300°F oven for 5 to 8 minutes until warm and slightly toasty.
