If you’re staring at a pile of summer zucchini and wondering what sweet magic you can create — look no further. These zucchini bars are about to become your new favorite way to sneak veggies into dessert. They’re moist, spiced just right, and topped with a silky cream cheese frosting that makes every bite irresistible.

Think of these bars as a cross between zucchini bread and sheet cake — only better. They’re dense (in a good way), easy to whip up, and crowd-pleasing whether you serve them cold from the fridge or fresh out of the oven. Oh, and did we mention they can be passed off as breakfast?

Why These Are The BEST Zucchini Bars

Let’s break down what makes these bars stand out from the rest:

Unbelievably moist texture thanks to grated zucchini
Light spice from cinnamon and nutmeg
No raisins or nuts to mess with the soft crumb (unless you’re into that!)
A thick, rich layer of cream cheese frosting that sets beautifully
Easy to make in one bowl — yes, really

Plus, zucchini is more than just filler — it’s nutritious, too. Zucchini is low in calories but high in vitamins, minerals, and water content. Check out its nutritional value here if you’re curious about why it’s such a sneaky superstar in baking.

And speaking of sneaky — don’t worry about pan sizes or baking math. If you’re adjusting from a 9×13 to a sheet pan, the King Arthur Baking Pan Guide has your back with exact conversions.

Ingredients You’ll Need

Here’s your checklist for the best zucchini bars ever:

2 cups grated zucchini (squeezed to remove excess moisture)
2 cups all-purpose flour
1 teaspoon baking powder
1 teaspoon cinnamon
1/2 teaspoon salt
1/8 teaspoon nutmeg
1 cup light brown sugar
3/4 cup melted coconut oil (or sub with vegetable oil)
3 large eggs, lightly beaten
2 teaspoons vanilla extract

For the Cream Cheese Frosting:

2 blocks (8 oz each) cream cheese
1/2 cup unsalted butter, softened
2 1/2 cups powdered sugar
1 teaspoon vanilla extract

Step-by-Step Instructions

Let’s get baking:

Prep your pan: Spray a 10×15” sheet pan with nonstick spray (or line with parchment).
Prep the zucchini: Grate your zucchini, then wrap it in a kitchen towel and squeeze out as much water as possible.
Mix the dry ingredients: In a bowl, whisk together the flour, baking powder, cinnamon, salt, and nutmeg.
Mix the wet ingredients: In a large bowl, whisk the brown sugar, coconut oil, eggs, and vanilla.
Combine: Slowly fold the dry mixture into the wet mixture. Then add the zucchini and mix until evenly combined.
Bake: Pour the batter into the pan and bake at 350°F for 30–35 minutes or until the center is set and springs back.
Cool: Let the bars cool completely before frosting.

How to Make the Perfect Cream Cheese Frosting

Beat softened cream cheese and butter together until fluffy
Gradually mix in powdered sugar
Stir in vanilla extract
Spread generously over the cooled bars

You can even pop them in the fridge — trust us, they’re next-level cold.

Variations to Try

Want to remix your bars? Here are a few tasty twists:

Add mini chocolate chips for a zucchini-brownie hybrid
Mix in lemon zest and sub some vanilla with lemon extract for a citrusy zing
Use applesauce in place of oil for a lower-fat option
Add shredded coconut or toasted walnuts (if you’re team nuts)

Common Mistakes to Avoid

To keep your zucchini bars from turning into a soggy mess:

Squeeze the zucchini well — moisture is your enemy here
Don’t over-mix the batter
Stick with the recommended pan size for even baking
Let them cool before frosting — or the frosting melts into goo

How to Store and Freeze

These bars keep beautifully. Here’s how:

Store in an airtight container in the fridge for up to 5 days
Freeze in layers separated by parchment for up to 3 months
Thaw overnight in the fridge before serving

Pro tip: Cut them before freezing for grab-and-go servings.

With coffee for brunch or breakfast
As a light summer dessert at BBQs

With a dusting of cinnamon on top for flair

Frequently Asked Questions

Should I peel the zucchini before grating?
Nope! The peel is soft, nearly invisible when baked, and adds a tiny bit of extra fiber.

Why are my zucchini bars soggy?
Chances are you didn’t squeeze the zucchini dry enough. Wring it out thoroughly!

Can I use frozen zucchini?
Yes — thaw and drain it well before adding to the batter.

Is it okay to substitute coconut oil?
Definitely. Use vegetable oil, melted butter, or even applesauce for a healthier twist.

Can I make these gluten-free?
Absolutely — just swap in a 1:1 gluten-free flour blend.

Whether you serve them at your next picnic, potluck, or just munch on them straight from the fridge — they’re bound to be a hit.
