There’s a particular kind of comfort that comes from a warm loaf of bread cooling on the counter, filling the kitchen with the smell of peanut butter and melting chocolate. It’s the kind of smell that pulls people into the kitchen before you’ve even said a word about what’s baking.

How to Make Peanut Butter Chocolate Chip Zucchini Bread
This comes together as a simple two-bowl quick bread, no waiting on butter to soften or dough to chill.
Step 1: Prep the Pan and Oven
Preheat your oven to 350°F. Grease a 9×5-inch loaf pan and line it with parchment paper, leaving an overhang on the long sides for easy removal later.
Step 2: Prep the Zucchini
Grate the zucchini, then pat it with a clean towel to remove excess moisture. Don’t wring out every drop, though. A little extra water is part of what keeps this loaf so moist.
Step 3: Mix the Dry Ingredients
Whisk the flour, baking soda, baking powder, salt, and cinnamon together in a medium bowl. Set aside.
Step 4: Mix the Wet Ingredients
In a large bowl, whisk together the peanut butter, oil, granulated sugar, and brown sugar until smooth. Add the eggs one at a time, then stir in the vanilla. Fold in the grated zucchini.
Step 5: Combine and Fold in Chocolate Chips
Add the dry ingredients to the wet mixture and stir just until no streaks of flour remain. Overmixing leads to a tougher loaf, so stop as soon as it’s combined. Fold in about ¾ cup of the chocolate chips, reserving the rest for the top.
Step 6: Add the Peanut Butter Swirl and Bake
Pour the batter into your prepared pan and smooth the top. Warm the remaining 3 tablespoons of peanut butter for about 15 seconds to loosen it, then dot it over the batter and swirl gently with a knife. Scatter the reserved chocolate chips on top. Bake for 55 to 65 minutes, until a toothpick inserted in the center comes out clean or with a few moist crumbs.
Pro tip: If the top starts browning too quickly around the 35 to 40 minute mark, tent it loosely with foil for the rest of the bake. When testing for doneness, insert your toothpick away from a chocolate chip pocket, since melted chocolate can mimic wet batter.
Step 7: Cool Before Slicing
Let the loaf cool in the pan for 15 to 20 minutes, then use the parchment overhang to lift it out onto a wire rack. Cool completely, at least an hour, before slicing. Quick breads are delicate while warm, and cutting too soon will give you crumbly, uneven slices.

Frequently Asked Questions
Can I use natural peanut butter in this peanut butter chocolate chip zucchini bread?
Yes, but stir it thoroughly first, since natural peanut butter separates and its oil content varies by brand. If yours seems especially thin and drippy, consider cutting the oil back by a tablespoon to keep the batter from turning too loose.
Why did my peanut butter chocolate chip zucchini bread turn out dense or gummy in the middle?
This usually points to underbaking or too much moisture from the zucchini. Make sure to pat the zucchini dry before folding it in, and always test doneness with a toothpick inserted away from a chocolate chip pocket.
Can I make peanut butter chocolate chip zucchini bread ahead of time?
Absolutely. Like most quick breads, the flavor and texture actually improve overnight, so baking it a day ahead works in your favor. Wrap it tightly once fully cooled and store at room temperature or in the fridge until you’re ready to serve.
Do I need to peel the zucchini for this recipe?
No peeling required. The skin is thin and grates down finely, and any small green flecks blend in against the batter without affecting the flavor or texture at all.
