🛒 Ingredients for Zucchini Bars Without Flour

These bars use minimal, whole-food ingredients with a focus on nutrition and taste.

Wet Ingredients

  • 1 cup natural almond butter or peanut butter

  • 2 large eggs

  • 1 medium banana, mashed (or ½ cup applesauce)

  • ⅓ cup honey or maple syrup

  • 1 tsp vanilla extract

  • 1 cup finely grated zucchini, squeezed to remove excess water

Dry Ingredients

  • ½ cup rolled oats (gluten-free if needed)

  • 1 tsp ground cinnamon

  • ¼ tsp baking soda

  • ¼ tsp salt

Optional Add-ins

  • ¼ cup mini chocolate chips (dairy-free if needed)

  • ¼ cup chopped walnuts or sunflower seeds

  • 1 tbsp ground flaxseed or chia seeds


👩‍🍳 How to Make Flourless Zucchini Bars

Step 1: Prep the Pan and Oven

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

Step 2: Prepare the Zucchini

Grate zucchini using a fine grater. Place in a clean kitchen towel and squeeze out excess moisture—this keeps the bars from getting soggy.

Step 3: Mix Wet Ingredients

In a medium mixing bowl, stir together:

  • Almond butter

  • Eggs

  • Mashed banana (or applesauce)

  • Honey or maple syrup

  • Vanilla extract

Stir until smooth and well combined.

Step 4: Add Zucchini and Dry Ingredients

Mix in the grated, squeezed zucchini. Then fold in:

  • Oats

  • Cinnamon

  • Baking soda

  • Salt

Add any optional mix-ins at this point, like chocolate chips or seeds.

Step 5: Bake

Spread the batter evenly in the prepared pan. Bake for 25–28 minutes, or until the top is golden and a toothpick inserted into the center comes out mostly clean.

Let cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely before slicing.

❓ Frequently Asked Questions

Are these bars gluten-free?

Yes! As long as you use certified gluten-free oats, the bars contain no wheat or gluten.

Can I use frozen zucchini?

Yes, but be sure to thaw and squeeze out all excess water before adding it to the batter.

Can I skip the banana?

Absolutely. Replace it with ½ cup unsweetened applesauce or an extra tablespoon of nut butter for a firmer bar.

How dense are these?

They’re denser than traditional cake-style bars—think chewy, moist, and a bit fudgy in the center, thanks to the nut butter and oats.

Can I use a different sweetener?

Yes. Coconut sugar or date syrup can also work, but maple syrup or honey give the best consistency.
