Sometimes, the best treats come from the most unexpected combinations. This peanut butter zucchini sheet cake brings together the earthy sweetness of freshly shredded zucchini with the comforting warmth of peanut butter and a touch of chocolate. It’s one of those recipes that quietly sneaks its way into your rotation, especially when you want a dessert that feels both homey and a little adventurous.
One afternoon, I pulled this cake from the oven just as rain started tapping against the kitchen window. The smell was incredible—nutty, a little sweet, and deeply inviting. I remember hesitating, unsure if zucchini really belonged in cake, but the first bite erased any doubt. The texture was moist without being heavy, and the chocolate chips melted into little pockets of surprise. I was distracted halfway through by a phone call and somehow ended up with more crumbs on the counter than on my plate, but that’s the charm of this cake—it’s comfort food that doesn’t ask for perfection.
- It’s surprisingly moist thanks to the zucchini, which means it feels indulgent without being overly dense.
- The peanut butter flavor shines through but doesn’t overpower, making it approachable even if you’re not a huge peanut butter fan.
- Chocolate chips add a little melty sweetness, balancing the earthiness in a way that’s just right.
- The recipe is straightforward—no fancy equipment or obscure ingredients needed.
- It’s simple—and that’s kind of the point. This cake isn’t about fuss; it’s about comfort.
If you’re worried about the zucchini, don’t be. It disappears into the batter, adding moisture and a subtle depth that you might not expect but will definitely appreciate. And if you’re looking for a dessert that’s a little different but still hits that cozy, nostalgic note, this cake is worth a try.

Description
A moist and flavorful peanut butter zucchini sheet cake that combines the sweetness of zucchini with rich peanut butter and chocolate chips, perfect for any occasion.
Ingredients
2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt
1 cup granulated sugar
1 cup packed brown sugar
1 cup creamy peanut butter
1/2 cup vegetable oil
3 large eggs
2 teaspoons vanilla extract
2 cups shredded zucchini, squeezed dry
1 cup semisweet chocolate chips
1/2 cup chopped peanuts (optional)
Instructions
Preheat the oven to 350°F (175°C). Grease and flour a 9×13-inch sheet pan.
In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Set aside.
In a large bowl, beat the granulated sugar, brown sugar, and creamy peanut butter until creamy and well combined.
Add the vegetable oil, eggs, and vanilla extract to the peanut butter mixture and beat until smooth.
Gradually add the dry ingredients to the wet ingredients, mixing just until combined.
Fold in the shredded zucchini and semisweet chocolate chips until evenly distributed.
Pour the batter into the prepared sheet pan and spread evenly.
Sprinkle the chopped peanuts evenly over the top, if using.
Bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean.
Allow the cake to cool completely in the pan on a wire rack before cutting into squares and serving.

Kitchen Notes: I usually bake this in a standard sheet pan, nothing fancy needed. It’s great served warm with a scoop of vanilla ice cream or just on its own with a cup of tea. Sometimes I toss in a handful of chopped peanuts on top for extra crunch, but that’s just me experimenting. I haven’t tested it with other nut butters, but peanut butter really brings that classic flavor. If you want a twist, try adding cinnamon or swapping the chocolate chips for butterscotch—though I can’t promise it’ll be quite the same.
