Zucchini floods the farmers markets and gardens in summer, and while I enjoy it in savory dishes like this easy zucchini casserole or zucchini biscuits, I especially love baking with it. In fact, I’ve shared plenty of my favorite zucchini recipes here on my blog.

Why zucchini? It adds moisture without any veggie flavor — just pure, invisible hydration that keeps baked goods tender, even ones as rich as this peanut butter zucchini loaf or chocolate zucchini cake.

Pantry Staples and Key Ingredients

• 1 and 2/3 cups (208g) all-purpose flour (spooned and leveled)
• 1 teaspoon baking powder
• 1/2 teaspoon baking soda
• 1/2 teaspoon salt
• 1 teaspoon ground cinnamon
• 1/3 cup (80ml) vegetable or olive oil
• 1/2 cup (125g) creamy peanut butter (processed or natural)
• 2/3 cup (133g) packed light or dark brown sugar
• 1/3 cup (113g) honey
• 2 large eggs, room temperature
• 1/3 cup (80ml) milk (any kind), room temperature
• 1 teaspoon pure vanilla extract
• 1 and 1/2 cups (180g) shredded zucchini (no need to blot)
• 1 cup (180g) semi-sweet chocolate chips

Mixing and Baking Instructions

1. Preheat oven to 350°F (177°C) and grease a 9×5-inch loaf pan or line with parchment (for muffins, prepare muffin pan and liners).
2. Shred zucchini to yield 1 1/2 cups (about 180g); no need to blot or squeeze (peel optional).
3. In a large bowl, whisk together 1 2/3 cups all-purpose flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda, 1/2 teaspoon salt, and 1 teaspoon ground cinnamon.
4. In a medium bowl, whisk 1/3 cup oil, 1/2 cup creamy peanut butter, 2/3 cup packed brown sugar, 1/3 cup honey, 2 large room-temperature eggs, 1/3 cup room-temperature milk, and 1 teaspoon vanilla until smooth.
5. Pour the wet ingredients into the dry ingredients and stir gently until just combined — do not overmix.
6. Fold in the shredded zucchini and 1 cup semi-sweet chocolate chips with a spatula until evenly distributed.

7. Pour the batter into the prepared loaf pan and smooth the top.

8. Bake the loaf 55–70 minutes at 350°F (177°C), start checking at 55 minutes and tent with foil halfway through if the top is browning too quickly.
9. Test doneness by inserting a toothpick in the center; it should come out clean or with a few moist crumbs; if not done, bake longer and check every 5–10 minutes.
10. Cool the loaf in the pan on a wire rack for 1 hour before removing; cool completely for neater slices.
11. (Muffin option) Fill 15 muffin liners to the top; bake at 425°F (218°C) for 5 minutes, then reduce heat to 350°F (177°C) and bake 16–18 more minutes; cool 5 minutes in pan, then transfer to a wire rack.

Tips for a Tender Loaf

This peanut butter zucchini loaf comes together quickly using only a couple of bowls, a whisk, and a grater—my go-to tool for shredding zucchini for fritters and all sorts of baked goods.

Important: No need to squeeze or blot the shredded zucchini — all that moisture is a key part of what makes this loaf so tender.

How much zucchini do you need?

Depending on size, 1 to 2 medium zucchini will give you the 1 1/2 cups shredded zucchini (about 180g) that this recipe calls for.

Do you have to peel the zucchini?

Nope! You can shred it with the skin on. But if you have picky eaters who might notice green flecks, peeling the zucchini is an easy way to keep the bread looking uniform. It doesn’t change the taste or texture either way.

The smell while this peanut butter zucchini loaf bakes is absolutely heavenly! It’s wonderful slightly warm right from the oven, but don’t miss trying it on day two when all those flavors have blended perfectly. I can’t wait for you to give it a try!

Easy Swaps and Muffin Option

Yes, you can absolutely turn this batter into peanut butter chocolate chip zucchini muffins! The recipe makes enough batter for 15 muffins — full instructions live in the Notes section below.

Notes

1. Freezing Instructions: Freeze baked and cooled loaf or muffins wrapped tightly for up to 3 months. Thaw overnight in the fridge, then warm if you like.
2. Muffin Baking: This recipe makes about 15 muffins. Use liners and follow the instructions above for best results.
3. Whole Wheat Flour: You can swap all-purpose for whole wheat flour without other changes. The loaf will be a bit denser but still delicious.
4. Honey Swaps: I recommend sticking to a mix of honey and brown sugar for moisture and flavor. If you want no honey, try pure maple syrup or granulated sugar instead.

Storage, Freezing, and Reheating

Here’s how to store and enjoy your peanut butter zucchini loaf for days:

• Room temperature: Cover and store your cooled loaf tightly for up to 5 days on the counter.
• Refrigerator: Keep covered in the fridge for up to a week.
• Freezing: Wrap and freeze the whole cooled loaf or individual slices for up to 3 months. Thaw overnight in the fridge and warm before serving if you like.
• Reheating: Warm slices in the microwave for 10–20 seconds or in a 300°F (150°C) oven for 8–12 minutes.
• Make-ahead: Bake ahead and freeze whole or slice into muffins for quick, portable snacks anytime.

Frequently Asked Questions

• How much zucchini do I need? Use 1 to 2 medium zucchini to yield about 1 1/2 cups (180g) shredded zucchini — just right for this loaf.
• Do I need to peel or blot the zucchini? Nope! No peeling needed unless you want to hide green flecks, and don’t blot it—letting all that moisture keep the bread tender is key.
• What kind of peanut butter is best? Stick to smooth and creamy peanut butter, natural or processed. Crunchy peanut butter can dry out the loaf.
• Can I make muffins instead of a loaf? Absolutely! This recipe makes about 15 muffins. Fill liners full, bake at high temp briefly, then lower oven and finish baking — full details in the Notes.
• Can I substitute whole wheat flour? Yes, feel free to swap it 1:1. The texture will be denser but still great.
• What if I want to swap honey? You can replace the honey with pure maple syrup or white sugar, but I don’t recommend using all honey for this one.
• How do I know when the bread is done? A toothpick inserted in the center should come out clean or with just a few moist crumbs. Tent with foil mid-bake if the top browns too fast.
