💚 Why You’ll Love These Oatmeal Zucchini Bars

When you need a snack that’s nutritious, satisfying, and just a little sweet, these Oatmeal Zucchini Bars are a go-to recipe. They’re packed with wholesome oats, naturally moist from shredded zucchini, and sweetened with banana and maple syrup for a clean-eating treat that feels indulgent without being over the top.

Perfect for breakfast, snack time, or even dessert, these bars are:

  • Naturally sweetened with fruit and maple

  • Full of fiber from whole oats and zucchini

  • Easy to make in one bowl

  • Free from refined sugar, alcohol, pork, and bacon

  • Easily adaptable for gluten-free, vegan, or dairy-free diets


🥒 What Makes These Bars Stand Out?

Whole-Grain Goodness

Rolled oats provide a chewy texture and lasting energy, while oat flour (or whole wheat) keeps the bars tender and satisfying.

Naturally Moist

Shredded zucchini and mashed banana create a soft, tender bar with no need for heavy oils or butter.

Customizable Sweetness

These bars are naturally sweetened with banana and maple syrup, but you can make them sweeter—or less—depending on your taste.

Family-Friendly & Meal Prep–Approved

Bake a batch, cut into squares, and enjoy all week. Great for lunchboxes, work snacks, or a healthier dessert.


📋 Ingredients for Oatmeal Zucchini Bars

Dry Ingredients:

  • 1 ½ cups rolled oats (certified gluten-free if needed)

  • ½ cup oat flour or whole wheat flour

  • 1 tsp cinnamon

  • ½ tsp baking soda

  • ¼ tsp salt

Wet Ingredients:

  • 1 ripe banana, mashed (about ½ cup)

  • 1 cup shredded zucchini (lightly squeezed)

  • ¼ cup maple syrup or honey

  • 1 egg (or flax egg for vegan option)

  • ¼ cup melted coconut oil or avocado oil

  • 1 tsp vanilla extract

Optional Add-ins:

  • ¼ cup chopped walnuts or pecans

  • 2 tbsp dark chocolate chips (dairy-free if needed)

  • 2 tbsp raisins or dried cranberries


🧁 How to Make Oatmeal Zucchini Bars

🔥 Step 1: Preheat the Oven

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

🍌 Step 2: Mix the Wet Ingredients

In a large bowl, whisk together:

  • Mashed banana

  • Maple syrup

  • Egg (or flax egg)

  • Melted coconut oil

  • Vanilla extract

Stir in the shredded zucchini until evenly incorporated.

🥄 Step 3: Combine Dry Ingredients

In a separate bowl, mix:

  • Oats

  • Oat flour or whole wheat flour

  • Cinnamon

  • Baking soda

  • Salt

Add the dry mixture to the wet ingredients and stir until combined.

🌰 Step 4: Fold in Optional Add-ins

Stir in any extras like chopped nuts, chocolate chips, or raisins. Don’t overmix.

🧱 Step 5: Bake

Pour the mixture into the prepared baking dish and smooth the top. Bake for 28–32 minutes, or until a toothpick comes out clean and edges are lightly golden.

❄️ Step 6: Cool and Slice

Allow bars to cool completely in the pan before slicing into squares. Store in an airtight container.

✅ Recipe Success Tips

Lightly Squeeze Zucchini

Zucchini holds a lot of water. Wrap it in a clean towel or paper towel and give it a gentle squeeze—don’t wring it bone-dry.

Use Very Ripe Banana

The riper the banana, the sweeter and more flavorful your bars will be.

Don’t Overbake

Bake until just golden at the edges and the center is firm. Overbaking can make them dry.


🌀 Substitutions & Variations

  • Gluten-Free: Use certified gluten-free oats and oat flour

  • Vegan: Replace the egg with a flax egg (1 tbsp ground flax + 3 tbsp water)

  • Dairy-Free: This recipe is naturally dairy-free unless you add chocolate chips with dairy

  • No Banana: Use ¼ cup applesauce instead (texture will be slightly different)

  • Add Protein: Mix in 1–2 tablespoons of hemp seeds or protein powder (adjust liquid slightly)


❓ Frequently Asked Questions (FAQs)

Q1: Can I make these bars ahead of time?

Yes! These bars store beautifully. Keep them in an airtight container:

  • At room temp: Up to 2 days

  • In the fridge: Up to 5–6 days

  • In the freezer: Up to 3 months (freeze sliced bars individually)

Q2: Can I use quick oats instead of rolled oats?

You can, but the texture will be softer and less chewy. Rolled oats work best for structure.

Q3: Can I skip the banana?

Yes. Replace with ¼ cup applesauce or ⅓ cup mashed sweet potato for a banana-free version.

Q4: Do these bars taste like vegetables?

Not at all! The zucchini is mild and mostly undetectable in taste. The banana and maple syrup shine through.

Q5: Can I add frosting or glaze?

Certainly! A drizzle of nut butter, Greek yogurt topping, or even a light powdered sugar glaze (for a more indulgent twist) works beautifully.


🍽 Serving Suggestions

  • Pack into lunchboxes for a school-friendly snack

  • Serve with herbal tea or a glass of almond milk

  • Crumble into yogurt bowls for a crunchy topping

  • Warm slightly and top with nut butter for breakfast
