Ingredients You’ll Need
This Raspberry Swirl Zucchini Brownies Recipe uses simple ingredients that come together in harmony to create layers of flavor, texture, and that irresistible chocolate and fruit swirl you’ll love. Each component plays its part – from the cocoa powder that delivers deep chocolate richness to the zucchini that keeps the brownies incredibly moist without overpowering the taste.
- 1 ½ cups all-purpose flour: Provides structure to the brownies, balancing the moisture for that perfect chew.
- ½ cup unsweetened cocoa powder: Adds intense chocolate flavor and a beautiful dark color.
- 1 tsp baking powder: Gives the brownies a slight lift, keeping them from becoming too dense.
- ¼ tsp salt: Enhances all the flavors and balances the sweetness.
- 1 ½ cups granulated sugar: Sweetens the brownies, creating that classic dessert appeal.
- 1 cup unsweetened applesauce: A smart substitute for oil that keeps things moist and adds a mild sweetness.
- 2 large eggs: Acts as a binder and brings richness to the batter.
- 1 tsp vanilla extract: Brightens the flavor with warm, aromatic notes.
- 1 ½ cups grated zucchini (about 1 medium zucchini, excess water squeezed out): Adds moisture, sneaks in some veggies, and keeps the brownies tender.
- ½ cup chocolate chips (optional): For those who want extra pockets of melty chocolate goodness.
- 1 cup fresh or frozen raspberries: The star of the raspberry swirl, providing tartness and vibrant color.
- 2 tbsp granulated sugar: Sweetens the raspberry sauce to balance the natural tartness.
- 1 tbsp lemon juice: Adds brightness and helps the raspberry sauce thicken beautifully.
How to Make Raspberry Swirl Zucchini Brownies Recipe
Step 1: Preheat and Prep
Start by heating your oven to 350°F (175°C). Prepare an 8×8-inch baking pan by greasing it or lining it with parchment paper. This simple prep keeps your brownies from sticking and makes cleanup a breeze.
Step 2: Prepare the Raspberry Swirl
Combine the raspberries, sugar, and lemon juice in a small saucepan. Warm over medium heat, stirring gently until the raspberries break down and turn into a thick, luscious sauce — usually about 5 to 7 minutes. Remove from heat and let it cool so it’s ready to be swirled into your brownie batter.
Step 3: Mix the Brownie Batter
In one bowl, whisk together the flour, cocoa powder, baking powder, and salt. In another, mix the sugar, applesauce, eggs, and vanilla extract until smooth and creamy. Add the grated zucchini to the wet ingredients, mixing thoroughly to combine the velvety moisture with the other wet elements.
Step 4: Combine Wet and Dry Ingredients
Slowly add the dry mixture to the wet, stirring gently until just combined. This keeps the brownies tender and fudgy. If you’re feeling indulgent, fold in the chocolate chips now to sprinkle pockets of melty chocolate throughout.
Step 5: Assemble and Swirl
Pour your brownie batter evenly into the prepared pan. Then, drop spoonfuls of that gorgeous raspberry sauce across the top. Use a knife or skewer to swirl the sauce throughout the batter, creating those beautiful raspberry ribbons that make these brownies extra special.
Step 6: Bake!
Bake for 30 to 35 minutes. To check doneness, insert a toothpick into the center – a few moist crumbs mean it’s perfectly fudgy. Let your Raspberry Swirl Zucchini Brownies Recipe cool completely on a wire rack before slicing to enjoy that perfect texture.
How to Serve Raspberry Swirl Zucchini Brownies Recipe

Garnishes
Serving these brownies with a dusting of powdered sugar, a dollop of whipped cream, or even a scoop of vanilla ice cream takes them from everyday treat to elegant dessert in seconds. Fresh raspberries on top add a pop of color and tartness that pairs beautifully with the chocolate.
Side Dishes
Pair your brownies with a fresh fruit salad for a lighter complement, or a hot cup of coffee or tea to balance the sweet and tangy flavors. For brunch or afternoon tea, they go wonderfully alongside almond or coconut milk lattes.
Creative Ways to Present
For an eye-catching presentation, cut the brownies into small bite-sized squares and serve on a platter with toothpicks. You can also sandwich two brownie squares with raspberry jam for an extra burst of fruit flavor. Or place chunks in a glass with layers of Greek yogurt and extra raspberries to make a chocolatey trifle that wows guests.
Make Ahead and Storage
Storing Leftovers
Keep your Raspberry Swirl Zucchini Brownies Recipe fresh by storing leftovers in an airtight container at room temperature for up to 3 days. They taste best once they’ve had time to set, allowing the flavors to deepen and the texture to settle wonderfully.
Freezing
If you want to save some for later, wrap individual brownies tightly in plastic wrap and place them in a freezer-safe container. Frozen brownies can last up to 3 months and thaw beautifully at room temperature or in the fridge overnight.
Reheating
To enjoy a warm brownie, microwave a square for about 15 to 20 seconds or warm it gently in a low oven. The raspberry swirls will become even more fragrant, and the gooey texture will remind you why this Raspberry Swirl Zucchini Brownies Recipe is so loved.
FAQs
Can I use frozen zucchini for this recipe?
Yes! Just be sure to thaw and squeeze out all excess water from the zucchini before grating. This helps keep the brownies from becoming too wet.
Do I have to use fresh raspberries, or can I use frozen?
Frozen raspberries work perfectly here. Just thaw them slightly before making the swirl, so they break down more easily while cooking.
Is applesauce necessary, or can I substitute oil?
You can substitute oil if you prefer a richer brownie, but applesauce keeps the brownies moist while reducing fat, making this recipe a bit lighter without losing flavor.
Can I make this recipe gluten-free?
Absolutely! Use a gluten-free all-purpose flour blend that measures cup-for-cup like regular flour, and you’re good to go.
What if I don’t want chocolate chips in my brownies?
No problem at all! The brownies are delicious without them; the rich cocoa and raspberry swirl provide plenty of flavor without extra mix-ins.

If you want to impress friends or satisfy a personal craving, the Raspberry Swirl Zucchini Brownies Recipe is your golden ticket to a soulful dessert that’s both healthy-ish and downright delicious.

Ingredients
Dry Ingredients
- 1 ½ cups all-purpose flour
- ½ cup unsweetened cocoa powder
- 1 tsp baking powder
- ¼ tsp salt
Wet Ingredients
- 1 ½ cups granulated sugar
- 1 cup unsweetened applesauce
- 2 large eggs
- 1 tsp vanilla extract
- 1 ½ cups grated zucchini (about 1 medium zucchini, excess water squeezed out)
Additional Ingredients
- ½ cup chocolate chips (optional)
Raspberry Swirl
- 1 cup fresh or frozen raspberries
- 2 tbsp granulated sugar
- 1 tbsp lemon juice
Instructions
- Preheat the oven: Preheat your oven to 350°F (175°C). Grease or line an 8×8-inch baking pan with parchment paper to prevent sticking and ensure easy removal of the brownies.
- Prepare the raspberry swirl: In a small saucepan, combine the raspberries, granulated sugar, and lemon juice. Heat over medium heat, stirring occasionally, until the raspberries break down and the mixture thickens, about 5-7 minutes. Remove from heat and set aside to cool.
- Prepare the brownie batter: In a large mixing bowl, whisk together the all-purpose flour, cocoa powder, baking powder, and salt until well combined. In a separate bowl, mix the granulated sugar, unsweetened applesauce, eggs, and vanilla extract until smooth. Fold the grated zucchini into the wet ingredients, making sure it is evenly incorporated.
- Combine the wet and dry ingredients: Gradually add the dry ingredients to the wet ingredients, gently stirring until just combined. Avoid overmixing to keep the brownies tender. If using, fold in the chocolate chips evenly throughout the batter.
- Assemble the brownies: Pour the brownie batter into the prepared baking pan and smooth the surface evenly. Spoon dollops of the cooled raspberry sauce over the batter, then use a knife or skewer to gently swirl the raspberry mixture into the batter, creating a marbled effect.
- Bake the brownies: Place the pan in the preheated oven and bake for 30-35 minutes. Test for doneness by inserting a toothpick into the center; it should come out mostly clean with a few moist crumbs but no wet batter.
- Cool and serve: Remove the brownies from the oven and allow them to cool completely in the pan on a wire rack. Once cooled, slice into 16 squares and serve to enjoy a moist, chocolatey treat with a fresh raspberry twist.
Notes
- Be sure to squeeze out excess water from the grated zucchini to avoid making the batter too wet.
- Using parchment paper makes it easier to remove brownies from the pan.

- For a richer flavor, consider using bittersweet chocolate chips.
- Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
