Fudgy Double Chocolate Zucchini Beet Brownies

Jump to Recipe

Do not dismiss these double chocolate zucchini and beet brownies until you have tasted them. They are deeply chocolatey, rich, fudgy, and layered with a subtle balance of flavors. For the best texture and flavor, let the brownies rest in the refrigerator overnight. The extra time allows the chocolate, cocoa, espresso, zucchini, and beetroot to blend beautifully into one irresistible bite.

Fudgy brownies are one of my favorite snack-time treats. They are the kind of dessert I like to enjoy slowly, preferably without distractions. A good brownie can be comforting, indulgent, and deeply satisfying, especially when it has that dense, moist center and a glossy chocolate finish.

I decided to add vegetables to these brownies to make them a little more interesting and to bring in natural moisture. Zucchini works well in chocolate desserts because it melts into the batter once baked, while beetroot adds moisture and a mild sweetness. Together, they help create a brownie that is soft, rich, and pleasantly fudgy without tasting like vegetables.

A little backstory: I first made a version of these fudgy vegetable brownies for my sister and her colleagues in the U.S. Army while they were deployed in Poland in August 2018. The response was warm and encouraging. Many of them could not believe the brownies contained vegetables. Later, when I wanted to recreate the recipe for my boys, I realized I had misplaced the notes I had written down. Since I planned to share the recipe, I had to start testing it again from scratch.

So, What Changed?

I went back to the kitchen and began experimenting. Not every vegetable works well in brownies. Some add too much water and make the texture more cakey than fudgy. In the earlier version, spinach and zucchini released a lot of moisture, so the brownies did not turn out quite the way I wanted. I eventually removed the spinach and kept testing until I found a better balance.

Beetroot turned out to be a great addition. It helped keep the brownies moist and added a gentle natural sweetness without overpowering the chocolate. After several attempts, zucchini and beetroot became the winning combination. These double chocolate zucchini and beet brownies are dark, fudgy, rich, and incredibly satisfying. They are also made without refined sugar, which makes them feel a little more “healthy-ish” while still tasting like a proper dessert.

How to Make Double Chocolate Zucchini Fudgy Brownies

These homemade chocolate zucchini brownies are simple to prepare and perfect for anyone who loves a dense, moist brownie. The dark chocolate gives the brownies their deep flavor, the cocoa powder intensifies the chocolate taste, and a little espresso helps bring everything together. The zucchini should be grated and squeezed to remove excess water, while the beetroot should be cooked and grated before being folded into the batter.

To make these fudgy brownies, you will need:

Butter, at room temperature
Dark chocolate bars, chopped
Instant espresso
Hot water
Swerve sweetener or another granulated sweetener
Eggs
All-purpose flour
Dark cocoa powder
Salt
Zucchini, grated and squeezed to remove excess water
Beetroot, cooked and grated
Walnuts, optional
Semi-sweet chocolate, optional

Method

Preheat the oven to 350°F. Line an 8-inch baking pan with foil or parchment paper, then spray it generously with cooking spray. Set aside.
Dissolve the instant espresso in hot water and set it aside.
Place the chopped dark chocolate and butter in a heat-resistant bowl set over a saucepan with about an inch of simmering water. Make sure the bottom of the bowl does not touch the water. Stir gently in a circular motion until the chocolate and butter are fully melted. Remove from the heat and allow the mixture to cool slightly.
Transfer the melted chocolate mixture to the bowl of an electric mixer. Add the sweetener and mix on medium speed for about 3 minutes, or until smooth.
Add the eggs one at a time, mixing well after each addition. Beat for about 4 minutes until the mixture looks slightly airy. Add the espresso mixture and beat for another minute.
In a separate bowl, whisk together the all-purpose flour, dark cocoa powder, and salt.
Fold the dry ingredients into the chocolate mixture until just combined. Gently fold in the grated zucchini, grated beetroot, walnuts, and chopped semi-sweet chocolate.
Spread the batter evenly in the prepared pan. Bake for 35 to 40 minutes, or until a toothpick inserted into the center comes out slightly sticky. Do not overbake if you want a fudgy texture.
Allow the brownies to cool in the pan on a wire rack for at least 2 hours, or refrigerate overnight for an even richer flavor. Remove from the pan and cut into squares.

Good to Know

If you are worried about tasting the vegetables, do not be. The dark chocolate and cocoa powder mask the flavor, leaving you with rich, chocolate-forward brownies.
Make sure the bowl sits snugly over the saucepan when melting the chocolate. The water should simmer gently and should not touch the bottom of the bowl.
Avoid boiling the water too hard. Excess steam can create water droplets, and even a small amount of water can cause melted chocolate to seize and become grainy or hard.
For cleaner slices, let the brownies cool completely before cutting. Chilling them overnight creates a firmer, fudgier texture.

If you are looking for easy chocolate desserts for a gathering, this double chocolate zucchini brownie recipe is a great place to start. It has the comfort of a classic brownie with the added moisture of zucchini and beetroot. Serve it as a dessert, snack, or sweet treat with coffee or tea.

Other chocolate treats to try include raspberry chocolate ganache, zucchini and beetroot cake, classic tiramisu, and a s’mores martini.

Save this healthy-ish zucchini brownies recipe for later and give it a try when you are craving a rich, fudgy chocolate dessert. If you love brownies, this recipe is a delicious way to enjoy a deep chocolate flavor with a little hidden vegetable goodness.

Peace & Love
