Super Fudgy Zucchini Brownies (Gluten Free & Dairy Free Options)

These double chocolate zucchini brownies have a rich, decadent flavor and fudgy texture, yet they're naturally sweetened and gluten free! The brownies get a double dose of chocolate flavor from cacao powder and chocolate chips, and a two ingredient frosting takes them over the top. Step-by-step VIDEO below!

Ingredients:

You can use regular all-purpose flour for this recipe OR gluten-free flour. I’ve tested the recipe with both Cup 4 Cup and Bob’s Red Mill Gluten Free 1-to-1 Baking Flour with fantastic results. The brownies also incorporate almond flour, which gives them a more tender texture. 

• Zucchini
• Neutral vegetable oil (such as grapeseed or avocado)
• Eggs
• Maple syrup or honey
• Vanilla extract
• Gluten-free 1-to-1 flour or regular all-purpose flour
• Almond flour
• Cacao powder or unsweetened cocoa powder
• Baking powder
• Chocolate chips

How to make zucchini brownies:

Instead of grating the zucchini (a task I despise, as mentioned in this easy carrot cake recipe), I took a cue from King Arthur Flour and decided to puree the zucchini into the batter. Pureeing the zucchini has a huge benefit: it adds loads of moisture to the brownies, allowing us to drastically cut back the amount of oil while keeping the brownies ultra moist. 

1. In a food processor, combine coarsely chopped zucchini, vegetable oil, eggs, maple syrup and vanilla.
2. Process until smooth (you’ll still see flecks of green).
3. Add flour, almond flour, cacao powder, baking powder and salt.
4. Pulse just until incorporated (don’t over-mix).

• Add chocolate chips or chopped dark chocolate and pulse to combine. Spread the batter into a lined 8x8-inch baking pan, and bake until a toothpick inserted in the center comes out clean (25-30 minutes).

Making the easy chocolate frosting

A two ingredient frosting takes the brownies over the top. In a small bowl, combine chocolate chips and milk (for dairy-free brownies use a dairy-free milk, such as nut milk). Microwave in 30 second intervals, stirring between each, until the chocolate is melted and smooth (alternatively, you can cook them in a double boiler on the stovetop). Spread the warm frosting over the cooled brownies.

Tips for making this recipe:

• This brownie batter gets made right in a food processor! You could also use a high speed blender, such as a Vitamix. (Check out my first book, The Food Processor Family Cookbook, for other recipes that use the food processor!)
• You’ll need 8-ounces of zucchini, which is about one 8-inch zucchini (it’s the equivalent of 2 scant cups of diced zucchini). 
• To make the brownies gluten free, use a gluten free all-purpose flour blend. I tested these brownies with Bob’s Red Mill Gluten Free 1-to-1 Baking Flour and Cup 4 Cup. 
• The brownies also incorporate almond flour, which gives them a more tender texture. 
• I suggest using dark chocolate chips in this recipe for a rich, chocolaty flavor (I use Guittard 63% chocolate chips).
• Using whole milk will give you the shiniest frosting, but you can use nut milk for a dairy free version.

Ingredients

• Cooking spray or coconut oil for pan

Brownies

• 1 8- ounce zucchini (about 8 inches long), trimmed and coarsely chopped (2 scant cups when cut into 1-inch dice)
• 2 tablespoons neutral vegetable oil
• 2 large eggs
• ½ cup maple syrup or honey
• 1 teaspoon vanilla extract
• ¾ cup (100g) gluten free 1-to-1 flour (such as Bob’s Red Mill or Cup 4 Cup, Bob’s Red Mill) OR ¾ cup (90g) regular all-purpose flour
• ¼ cup (30g) almond flour
• ½ cup (47g) raw cacao powder or good quality unsweetened cocoa powder
• ½ teaspoon baking powder
• ¼ teaspoon fine sea salt
• ½ cup bittersweet chocolate chips or chopped dark chocolate

Frosting

• ½ cup bittersweet chocolate chips
• 2 tablespoons milk or nut milk

Instructions

Make the brownies

• Preheat the oven to 350˚F (175˚C). Spray an 8x8-inch baking pan with cooking spray, or rub it with oil. Line the pan crosswise with parchment paper, leaving an overhang (this will make it easier to pull the brownies out later, but it's optional).
• In a food processor (or Vitamix), combine the zucchini, vegetable oil, eggs, maple syrup and vanilla. Process until smooth (you’ll still see flecks of green). Add the flour, almond flour, cacao powder, baking powder and salt. Pulse just until incorporated (don’t over-mix). Scrape the sides. Add the chocolate chips and pulse to combine.
• Scrape the batter into the prepared pan and spread it in an even layer. Bake until the top is matte and a toothpick inserted in the center comes out with damp crumbs, 25-30 minutes. Place the pan on a rack and let the brownies cool for 10 minutes. Using the parchment paper as handles, remove the brownies from the pan (you can skip this step and serve the brownies straight out of the pan if you prefer!). Let cool completely (the sides will shrink in slightly as it cools).

Make the frosting

• Combine the chocolate chips and milk in a small microwave safe bowl or double boiler. If microwaving, cook on high in 15 second intervals, stirring between each, until the chocolate is melted and shiny. If using a double boiler, cook over medium-low heat, stirring occasionally, until the chocolate is melted and shiny.
• Spread the warm frosting over the brownies. Let the brownies sit until the frosting is set (you can pop them in the fridge for 15 minutes to chill faster… and if you can’t wait that long and need to sneak a bite when the frosting is still melty and gooey, I get it). Slice the brownies and serve!

Notes

Storage: Store the brownies in an airtight container at room temperature for up to 3 days.
