Cooking Time

• Preparation: 15 minutes

• Baking: 25–30 minutes

• Cooling: 10 minutes

• Total Time: Approximately 55 minutes

Ingredients

• 1½ cups (135 g) rolled oats

• 1 medium zucchini (about 1 cup grated; ~120 g), squeezed dry

• ½ cup (120 ml) milk (dairy or plant-based)

• ¼ cup (60 ml) honey or maple syrup

• 1 large egg, room temperature

• 1 tsp vanilla extract

• ½ tsp baking powder

• ½ tsp ground cinnamon

• ¼ tsp salt

• Optional mix-ins (choose one or combine up to ½ cup total):

  • ¼ cup chopped nuts (walnuts or pecans)

  • ¼ cup chocolate chips

  • ¼ cup raisins or dried cranberries

Step-by-Step Cooking Directions

1. Preheat & Prep Pan: Preheat the oven to 350 °F (175 °C). Grease an 8×8-inch baking dish or line it with parchment paper, leaving an overhang for easy removal.

2. Grate & Drain Zucchini: Using the medium holes of a box grater (or a food processor), grate the zucchini. Place the grated zucchini in a clean kitchen towel, twist the towel, and squeeze firmly to remove excess moisture—this prevents the bars from turning soggy.

3. Combine Wet Ingredients: In a large mixing bowl, whisk together the milk, honey (or maple syrup), egg, and vanilla extract until smooth and well combined.

4. Whisk Dry Ingredients: In a separate bowl, stir the rolled oats, baking powder, cinnamon, and salt until evenly distributed.

5. Fold Together: Pour the dry mixture into the wet ingredients. Stir gently with a spatula until oats are fully moistened. Fold in the squeezed zucchini and any optional mix-ins (nuts, chips, or dried fruit) until evenly distributed.

6. Transfer to Pan: Scrape the batter into the prepared baking dish and spread it into an even layer, pressing gently to fill corners.

7. Bake: Place the dish on the center rack of the preheated oven. Bake for 25–30 minutes, or until the top turns golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.

8. Cool & Slice: Remove from the oven and set on a wire rack. Allow to cool in the pan for 10 minutes, then use the parchment overhang to lift the slab out. Transfer to the rack to cool completely before slicing into bars or squares.

• Customizable: Switch up the mix-ins each time—nuts one week, chocolate the next.

Health Benefits

Rolled oats provide slow-digesting complex carbohydrates and beta-glucan fiber, which supports heart health by helping to lower cholesterol. Zucchini adds vitamins A and C, potassium, and additional fiber. Nuts contribute healthy monounsaturated fats and protein, while optional dark chocolate chips can offer antioxidants. Using natural sweeteners like honey or maple syrup reduces refined sugar and delivers trace minerals. Overall, each bar supplies a balanced blend of macronutrients and micronutrients.

Serving Suggestions

• Breakfast On the Go: Pair a bar with a hard-boiled egg and a piece of fruit.

• Yogurt Parfait: Crumble a bar over Greek yogurt with fresh berries for layered texture.

• Chocolate-Nut Butter Sandwich: Spread peanut butter between two bars for a protein boost post-workout.

• Brunch Spread: Arrange bars on a platter with sliced fruit and mini quiches for guests.

Common Mistakes to Avoid

• Under-draining Zucchini: Excess moisture leads to soggy bars—squeeze thoroughly.

• Overbaking: Bars will dry out and become hard; remove when a toothpick shows slight moisture.

• Skipping Rest: Allow bars to cool completely before slicing to prevent crumbling.

• Uneven Spreading: Use a spatula to press batter into corners for uniform thickness and baking.

• High-Temperature Substitutions: Do not increase oven temperature—aim for 350 °F for even cook.

Pairing Recommendations

• Beverages: A steaming mug of black coffee or chai tea complements the sweetness and oats.

• Smoothies: Blend spinach, banana, and almond milk for added greens on the side.

• Juices: Freshly squeezed orange juice provides vitamin C to start your day.

• Milk or Milk Alternative: A cold glass balances the cake-like texture.

Cooking Tips

• Consistent Grating: Use the medium grater holes for zucchini—too fine yields gummy bars.

• Even Thickness: Ensure uniform layer in the pan (about 1.5 cm thick) so bars bake evenly.

• Make It Vegan: Replace egg with a flax “egg” (1 Tbsp flaxseed + 3 Tbsp water) and use plant-based milk.

• Add Texture: Stir in 2 Tbsp chia seeds or flaxseed meal for extra nutrition.

• Pan Prep: Line with parchment paper extending over the edges for easy removal without sticking.

Frequently Asked Questions

1. Can I use quick oats instead of rolled oats?
   Quick oats absorb liquid more rapidly, which can affect texture; you may need slightly less milk.

2. How do I store the bars?
   Keep in an airtight container at room temperature for up to 3 days, or refrigerate up to 7 days.

3. Can I freeze them?
   Yes—freeze individual bars in a zip-top bag for up to 1 month; thaw at room temperature.

4. What’s the best way to reheat?
   Warm in a toaster oven at 300 °F for 5 minutes or microwave for 15–20 seconds.

5. Why are my bars mushy?
   Likely too much liquid—ensure zucchini is well drained and do not overpour milk.

6. Can I omit the egg?
   Use a flax “egg” for binding, but texture will be slightly different.

7. How do I make them more protein-packed?
   Stir in 2 scoops of unflavored protein powder and reduce oats by ¼ cup.

8. Why didn’t the bars set?
   Check your baking powder’s freshness; old leavening agents lose potency.

9. Can I make them sugar-free?
   Substitute honey or syrup with mashed banana or unsweetened applesauce, adjusting liquid.

10. What pan size works best?
    An 8×8-inch dish yields 9 bars with ideal thickness; a 9×9-inch pan thins them slightly and reduces bake time by 2–3 minutes.
