🧾 Ingredients

🌱 Dry Ingredients:

  • 1 ½ cups old-fashioned rolled oats

  • ½ cup vanilla or unflavored protein powder (plant-based or whey)

  • 2 tbsp ground flaxseed

  • 1 tbsp chia seeds

  • 1 tsp ground cinnamon

  • ¼ tsp sea salt

🥒 Wet Ingredients:

  • 1 cup grated zucchini (squeeze out excess moisture)

  • ½ cup natural almond butter or peanut butter

  • ⅓ cup maple syrup or honey

  • 1 tsp vanilla extract

  • ¼ cup unsweetened almond milk (or any milk of choice)

👨‍🍳 How to Make Zucchini Protein Bars

Step 1: Prep the Zucchini

Grate the zucchini using a fine or medium grater. Place the grated zucchini in a clean towel or cheesecloth and squeeze out as much moisture as possible. This prevents soggy bars and helps them hold their shape.

Step 2: Mix Dry Ingredients

In a large bowl, combine:

  • Oats

  • Protein powder

  • Ground flaxseed

  • Chia seeds

  • Cinnamon

  • Salt

Stir to evenly distribute.

Step 3: Mix Wet Ingredients

In a separate bowl, stir together:

  • Nut butter

  • Maple syrup or honey

  • Vanilla

  • Milk

Mix until smooth. Stir in the grated zucchini.

Step 4: Combine and Fold

Add the wet mixture into the dry ingredients and stir until fully incorporated. If the mixture is too dry, add a tablespoon more milk. Fold in any optional add-ins like chocolate chips or seeds.

Step 5: Press and Chill

Line an 8×8-inch baking pan with parchment paper. Press the mixture firmly into the pan, smoothing the top with a spatula.

Chill in the refrigerator for at least 2–3 hours, or until firm. For a firmer texture, you can bake them (see below).


🔥 Optional: Bake for a Chewy Texture

Preheat your oven to 325°F (160°C). Bake the bars for 15–18 minutes until just set and golden around the edges. Cool completely before slicing.


🔪 How to Serve

  • Cut into 10–12 bars or squares

  • Wrap individually for easy grab-and-go snacks

  • Serve with a smoothie for a complete pre-workout meal

  • Crumble into Greek yogurt for a protein-packed parfait

🧊 How to Store Zucchini Protein Bars

In the Fridge:

Store in an airtight container for up to 7 days. They’re best served chilled or at room temperature.

In the Freezer:

Wrap individual bars and freeze for up to 2 months. Thaw overnight in the fridge or eat partially frozen for a chewy snack.


✅ Pro Tips for Perfect Protein Bars

💡 Squeeze Out Moisture

Zucchini holds water—removing it ensures your bars hold their shape and don’t become mushy.

💡 Use Quality Protein Powder

Choose a clean, minimal-ingredient protein powder for best taste and nutrition. Both plant-based and whey varieties work well.

💡 Press Tightly

Use a spatula or the bottom of a measuring cup to firmly press the mixture into the pan to prevent crumbling.


❓ Frequently Asked Questions

Yes, if you use certified gluten-free oats and gluten-free protein powder.

Is this recipe vegan?

It can be. Use maple syrup instead of honey, almond butter instead of peanut butter (if desired), and plant-based protein powder.

Absolutely. Bake at 325°F for about 15–18 minutes. Let them cool fully before slicing for clean cuts.
