Ingredients

Rich and fudgy brownies with hidden zucchini and the best frosting you’ll ever eat!

For the Brownies

  • 2 cups (248g) all-purpose flour
  • ½ cup (40g) unsweetened cocoa powder
  • 1 ½ teaspoons baking soda
  • 1 teaspoon salt
  • ½ cup (118g) vegetable oil
  • 1 ½ cups (300g) granulated sugar
  • 2 teaspoons vanilla extract
  • 2 cups shredded zucchini (1 large or 2 small zucchinis)
  • 3-5 tablespoons (15-75ml) water
  • ½ cup chopped walnuts (optional)

For the Frosting

  • 3 tablespoons (15g) unsweetened cocoa powder
  • ¼ cup (59ml) unsalted butter (melted)
  • 2 cups powdered sugar
  • ¼ cup (59ml) milk
  • 1 teaspoon vanilla extract
  • Pinch of salt

How to Make Zucchini Brownies

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Line your 9×13 baking pan with foil and spray it with cooking spray. Set aside.

Step 2: Mix Dry Ingredients

In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt until well combined. Set aside.

Step 3: Combine Wet Ingredients

Using an electric mixer fitted with a paddle attachment, mix together the vegetable oil, granulated sugar, and vanilla extract until well combined.

Step 4: Combine Everything Together

Add the dry ingredients from Step 2 into the wet mixture. Stir until just combined. Fold in the shredded zucchini. Let it sit for a few minutes so the batter can absorb moisture from the zucchini. If your mixture appears too dry or powdery, gradually add up to 5 tablespoons of water until you achieve a thick but spreadable batter.

Step 5: Bake the Brownies

Spread the batter evenly into your prepared baking pan. Bake for about 25-30 minutes or until they spring back gently when touched.

Step 6: Make the Frosting

In a separate bowl, whisk together melted butter, cocoa powder, salt, and powdered sugar until smooth. Whisk in milk and vanilla extract until fully combined.

Step 7: Frost and Serve

Once cooled, spread the frosting over your brownies. Cut into squares and chill slightly to allow the frosting to semi-set. Enjoy your delicious Zucchini Brownies!

These brownies will be best enjoyed within two days when stored in an airtight container. Chill them for an extra day of freshness!

How to Serve Zucchini Brownies

Zucchini brownies are a delicious treat that can be served in various delightful ways. Whether you’re hosting a gathering or enjoying them at home, these brownies will surely impress.

With Ice Cream

  • Top warm zucchini brownies with a scoop of vanilla or chocolate ice cream for a delightful dessert experience.

Drizzled with Chocolate Sauce

  • Enhance the chocolate flavor by drizzling rich chocolate sauce over the brownies just before serving.

Garnished with Fresh Berries

  • Add a fresh touch by serving your brownies with a side of mixed berries, like strawberries or raspberries.

A Dusting of Powdered Sugar

  • For a simple yet elegant presentation, sprinkle powdered sugar on top of the cooled brownies.

With Whipped Cream

  • Serve alongside whipped cream for a creamy contrast to the fudgy texture of the brownies.

Pair with Coffee or Tea

  • Enjoy your zucchini brownies with a cup of coffee or tea to balance the sweetness and add warmth.

How to Perfect Zucchini Brownies

Achieving the perfect zucchini brownies requires attention to detail. Here are some essential tips to ensure your brownies turn out fudgy and delicious.

  • Choose Fresh Zucchini: Use fresh, firm zucchinis for better moisture content and flavor.
  • Grate Finely: Grate the zucchini finely to ensure it blends well into the batter and remains hidden.
  • Adjust Water Carefully: Start with less water when mixing. Add gradually until you achieve a thick but spreadable consistency.
  • Check Baking Time: Keep an eye on baking time; ovens vary. Test if they spring back when touched lightly.
  • Cool Before Frosting: Allow your brownies to cool completely before adding frosting for better texture and taste.
  • Store Properly: Keep leftover brownies in an airtight container at room temperature or in the fridge to maintain their gooeyness.

Best Side Dishes for Zucchini Brownies

Zucchini brownies pair wonderfully with various side dishes that complement their rich flavor. Here are some great options:

  1. Vanilla Ice Cream: A classic pairing that adds creaminess and balances sweetness.
  2. Fruit Salad: A light, refreshing option that contrasts nicely with the dense brownie.
  3. Chocolate Mousse: Rich and velvety, this dessert enhances the chocolate experience.
  4. Coffee Cake: A cozy addition that works well for brunch gatherings alongside brownies.
  5. Nutty Granola: Serve crunchy granola as a topping for added texture and flavor contrast.
  6. Cheesecake Bites: Miniature cheesecakes offer a delightful creamy counterpart to chewy brownies.

Common Mistakes to Avoid

When making Zucchini Brownies, it’s essential to get the details right for the best results. Here are some common mistakes to avoid.

  • Boldly adding too much water – Zucchini has varying moisture levels. Start with a small amount of water and gradually add more until the batter is thick but not powdery.
  • Ignoring the oven temperature – Ensure your oven is preheated to 350°F. An unheated oven can lead to uneven baking and affect the texture of your brownies.
  • Skipping the cooling time – Allow the brownies to cool completely before frosting. This prevents the frosting from melting and ensures a better texture.
  • Not measuring zucchini correctly – Use properly shredded zucchini. Too much or too little can change the consistency, affecting the final outcome.
  • Overbaking – Keep an eye on your brownies during baking. They should spring back when touched gently. Overbaking can lead to dry brownies instead of fudgy ones.

Storage & Reheating Instructions

Refrigerator Storage

  • Store in an airtight container for up to 2 days.
  • Place parchment paper between layers if stacking to prevent sticking.

Freezing Zucchini Brownies

  • Wrap brownies tightly in plastic wrap and then in aluminum foil for up to 3 months.
  • Label containers with dates for easy tracking.

Reheating Zucchini Brownies

  • Oven – Preheat to 350°F, cover brownies with foil, and heat for about 10-15 minutes.
  • Microwave – Heat individual pieces on medium power for 10-15 seconds until warm.
  • Stovetop – Place brownies in a skillet over low heat, covering it until warmed through.
