Zucchini Bars: Moist, Lightly Sweet, and Perfect for Summer Snacking

When summer zucchinis are everywhere — in gardens, markets, and even gift baskets from neighbors — one of the best ways to use them is in a batch of soft, tender zucchini bars. Lightly sweet, gently spiced, and impossibly moist, zucchini bars are the perfect in-between snack. They’re not quite cake, not quite cookies — they’re just right.

I remember the first time I made zucchini bars. I had a counter full of squash, no butter, and a craving for something simple. The result was a pan of golden, spongy bars that were gone before they even cooled. Since then, I’ve played with the recipe to include gluten-free and vegan versions, all with the same irresistible texture and summer charm.

Whether you’re baking for school snacks, summer potlucks, or just a treat for yourself, these zucchini bars are a no-fail recipe you’ll come back to every season.

🛒 Ingredients for Classic Zucchini Bars

Dry Ingredients

• 1 ½ cups all-purpose flour
• 1 tsp baking powder
• ½ tsp baking soda
• ½ tsp salt
• 1 tsp cinnamon
• ¼ tsp ground nutmeg (optional)

Wet Ingredients

• 2 large eggs
• ½ cup granulated sugar
• ¼ cup brown sugar
• ½ cup neutral oil (vegetable or avocado oil)
• 1 tsp vanilla extract
• 1 ½ cups grated zucchini (lightly drained but not dry)

Optional Add-ins

• ½ cup chopped walnuts or pecans
• ¼ cup raisins or shredded coconut
• 2 tbsp ground flaxseed

👩‍🍳 How to Make Zucchini Bars

Step 1: Prep

Preheat oven to 350°F (175°C). Line an 8×8 or 9×9-inch baking pan with parchment paper or lightly grease.

Step 2: Grate the Zucchini

Use a box grater to shred unpeeled zucchini. Wrap in a clean towel and gently squeeze out excess moisture — but don’t overdo it. You want some moisture for softness.

Step 3: Mix the Dry Ingredients

In a bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg.

Step 4: Mix the Wet Ingredients

In a large bowl, whisk eggs and sugars until smooth. Stir in oil and vanilla, then fold in grated zucchini.

Step 5: Combine

Gradually add the dry ingredients to the wet. Mix just until combined. Fold in any optional add-ins.

Step 6: Bake

Spread the batter evenly into the prepared pan. Bake for 25–30 minutes, or until the top is golden and a toothpick comes out clean.

Let cool in the pan for 10–15 minutes before slicing into bars.

🌱 Vegan Zucchini Bars

To make this recipe vegan:

• Replace eggs with 2 flax eggs (2 tbsp flaxseed meal + 5 tbsp water, rested 10 min)
• Use maple syrup or coconut sugar for sweetener
• Ensure any add-ins (like chocolate or coconut) are vegan-friendly

Vegan zucchini bars are just as moist and delicious — a little earthier in flavor, but still crowd-pleasing and satisfying.

🌾 Gluten-Free Zucchini Bars

To go gluten-free:

• Replace the all-purpose flour with a 1:1 gluten-free baking blend
• Add ¼ tsp xanthan gum if your blend doesn’t include it
• Almond flour or oat flour can work too, but expect a slightly softer, more delicate texture

These gluten-free bars hold up well and are great with chopped nuts for added structure.

🔁 Zucchini Bar Variations

• Lemon Zucchini Bars: Add lemon zest and a drizzle of lemon glaze
• Spiced Bars: Use pumpkin pie spice for a fall twist
• Healthy Bars: Cut sugar in half and add applesauce or banana
• Nut-Free: Skip the nuts and try sunflower seeds or extra coconut
• Kid-Friendly: Add mini chocolate chips and skip the nuts for lunchbox treats

🍽️ How to Serve Zucchini Bars

Zucchini bars are incredibly versatile:

• As a snack: Enjoy plain or with a cup of tea
• With frosting: Spread with cream cheese or dairy-free glaze
• As breakfast: Pair with fruit and yogurt
• As dessert: Serve with vanilla ice cream or a drizzle of honey
• On the go: Wrap in wax paper for road trips and picnics

🧊 Storage & Freezing

Room Temp: Store in an airtight container for up to 3 days
Fridge: Keeps well for 5–6 days; let come to room temp before serving
Freezer: Freeze bars (wrapped individually) for up to 2 months

To thaw: Leave at room temp for 30 minutes or microwave for 10–15 seconds.

🔄 Baked vs. No-Bake Zucchini Bars

These are baked zucchini bars, which yield a cake-like texture. If you’re after no-bake, you’ll need ingredients like oats, nut butter, and a binder like dates or honey — perfect for a different type of snack bar. This article focuses on the baked variety for a soft, satisfying bite.
