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 a 9×13 baking pan with foil and spray it with cooking spray. Set this aside for later use.
Step 2: Mix Dry Ingredients
In a medium mixing bowl, whisk together the flour, cocoa powder, baking soda, and salt until well combined. Set this mixture aside.
Step 3: Combine Wet Ingredients
In another bowl, use an electric mixer fitted with a paddle attachment to mix together the vegetable oil, granulated sugar, and vanilla extract until fully integrated.
Step 4: Combine Wet and Dry Mixtures
Gradually add the dry mixture to the wet mixture. Stir until just combined. Fold in the shredded zucchini. Allow the mixture to sit for a few minutes so it can absorb moisture from the zucchini. If it feels too powdery, gradually add up to 5 tablespoons of water until you achieve a thick but manageable batter.
Step 5: Add Optional Nuts
If desired, fold in chopped walnuts at this stage. The dough will be very thick—similar to cookie dough—so you may need to use your hands to incorporate everything properly.
Step 6: Bake
Spread the brownie batter evenly in your prepared pan. Bake in the preheated oven for about 25-30 minutes or until they spring back when gently touched.
Step 7: Prepare the Frosting
While brownies are cooling, whisk together melted butter, cocoa powder, powdered sugar, milk, vanilla extract, and a pinch of salt until smooth.
Step 8: Frost Your Brownies
Once cooled, spread the frosting over your brownies. Cut them into squares and chill slightly so that they set well. Enjoy your gooey Zucchini Brownies!
These brownies are best eaten fresh but can last up to two days if stored properly in an airtight container. Enjoy!
How to Serve Zucchini Brownies
Zucchini brownies are a delightful treat that can be enjoyed in various ways. Whether you’re looking to elevate your dessert experience or simply want to add a personal touch, here are some creative serving suggestions.
Pair with Ice Cream
- Vanilla Ice Cream: A classic choice that complements the chocolate flavor and adds creaminess.
- Mint Chocolate Chip: The refreshing mint pairs wonderfully with the rich brownies for a flavorful contrast.
Top with Fresh Berries
- Raspberries: Their tartness enhances the sweetness of the brownies, creating a balanced bite.
- Strawberries: Sliced strawberries add a burst of freshness and make for an appealing presentation.
Drizzle with Chocolate Sauce
- Warm Chocolate Sauce: A warm drizzle adds an extra layer of indulgence, making each bite more decadent.
- Caramel Sauce: For those who love caramel, this sweet addition brings out the richness of the brownies.
Serve with Whipped Cream
- Homemade Whipped Cream: Light and fluffy, homemade whipped cream adds a lovely texture and taste.
- Flavored Whipped Cream: Consider vanilla or cinnamon-infused whipped cream for an added twist.
How to Perfect Zucchini Brownies
Perfecting zucchini brownies is all about achieving that rich, fudgy texture while balancing moisture. Here are some tips to ensure your brownies turn out just right.
- Measure zucchini properly: Shred your zucchini and then pack it lightly into the measuring cup. Too much can lead to overly moist brownies.
- Adjust water cautiously: Start with less water when mixing your batter. You can always add more if needed, but be careful not to make it too liquidy.
- Use fresh ingredients: Ensure your baking soda and cocoa powder are fresh for optimal rise and flavor.
- Don’t overmix: Mix until just combined. Overmixing can lead to dense brownies rather than a light, fudgy texture.
- Test doneness: Use a toothpick to check for doneness. It should come out with a few moist crumbs but not wet batter when they’re perfectly baked.
Best Side Dishes for Zucchini Brownies
While zucchini brownies are delicious on their own, they can be complemented by some tasty side dishes. Here are some great ideas to serve alongside.
- Fresh Fruit Salad: A mix of seasonal fruits adds brightness and balances the richness of the brownies.
- Cheese Platter: Mild cheeses like Brie or Gouda provide a savory contrast to the sweet chocolate flavors.
- Nutty Granola: Crunchy granola offers texture and can be sprinkled on top or served as a side for added crunch.
- Yogurt Parfait: Layer yogurt with granola and berries for a refreshing accompaniment that cuts through the sweetness.
- Chia Pudding: This creamy dessert is nutritious and provides a different texture that pairs well with brownie bites.
- Coffee or Espresso: A cup of coffee enhances chocolate flavors and gives a cozy finish to your dessert experience.
- Herbal Tea: A soothing herbal tea can cleanse the palate after indulging in these rich treats.
Common Mistakes to Avoid
Baking Zucchini Brownies can be a delightful experience, but there are some common pitfalls to watch out for.
- Bold phrase: Over-adding water – Adding too much water can make your brownies cakey instead of fudgy. Start with one tablespoon and only add more if necessary.
- Bold phrase: Neglecting zucchini moisture – Zucchini varies in moisture content. If your batter feels powdery, it indicates your zucchini might be too dry.
- Bold phrase: Not letting the batter rest – Allowing the batter to sit helps it absorb moisture from the zucchini, resulting in better texture. Don’t skip this step!
- Bold phrase: Skipping the foil lining – Lining your baking pan with foil and spraying it ensures easy removal and prevents sticking.
- Bold phrase: Ignoring cooling time – Frosting warm brownies can melt the icing. Let them cool completely before adding the frosting for the best result.
