🧁 How to Make Healthy Zucchini Bars

đŸ”„ Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper or lightly grease it with coconut oil.

đŸ„Ł Step 2: Combine Dry Ingredients

In a medium bowl, mix together:

  • Rolled oats

  • Whole wheat flour

  • Baking soda

  • Cinnamon

  • Nutmeg

  • Salt

Set aside.

đŸ„„ Step 3: Mix Wet Ingredients

In a large mixing bowl, whisk together:

  • Egg

  • Vanilla extract

  • Melted coconut oil

  • Maple syrup or honey

  • Applesauce or banana

đŸ„’ Step 4: Add Zucchini

Fold in the grated zucchini. If it’s very watery, give it a light squeeze using a clean kitchen towel or paper towel.

🌰 Step 5: Combine and Fold In Add-ins

Add the dry ingredients to the wet mixture and stir until just combined. Gently fold in any optional add-ins like nuts or chocolate chips.

đŸ§± Step 6: Bake

Pour the batter into your prepared pan and spread it evenly. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.

❄ Step 7: Cool and Slice

Let the bars cool in the pan for at least 15 minutes before transferring to a wire rack. Slice into bars once fully cooled.

✅ Tips for Success

Don’t Over-Squeeze the Zucchini

Zucchini should be lightly squeezed—just enough to avoid sogginess but still provide natural moisture.

Customize Your Sweetness

If you like things a bit sweeter, add 1–2 tbsp of coconut sugar or a few raisins for extra flavor.

Let Cool Completely Before Slicing

This helps the bars hold together without crumbling.


🔄 Substitutions and Variations

  • Gluten-Free: Use certified gluten-free oats and replace wheat flour with oat flour or almond flour (note texture may be softer).

  • Vegan: Swap the egg for a flax egg (1 tbsp ground flax + 3 tbsp water) and use maple syrup instead of honey.

  • Nut-Free: Skip the nuts or sub with sunflower seeds for crunch.


❓ Frequently Asked Questions (FAQs)

Absolutely. These bars store well and taste even better the next day. Store in the fridge for a grab-and-go snack.

Q2: Can I freeze healthy zucchini bars?

Q3: Do I need to peel the zucchini?

Q4: Can I turn this into muffins?

Yes, just divide the batter into a greased muffin tin and bake at 350°F for 18–22 minutes.
