Halloween is all about the thrill of the spooky and the sweet, and nothing says 'trick or treat' like a pan of fudgy brownies with a creepy-crawly spiderweb design. These Nutella Halloween Spiderweb Brownies are my favorite way to celebrate the season—they're rich, chocolatey, and come together in under an hour.

I remember the first time I made these with my niece. She was so excited to pipe the spiderwebs that she ended up with more Nutella on her face than on the brownies. That's the beauty of this recipe: it's forgiving, fun, and perfect for little hands to help with. The web design looks impressive, but it's surprisingly simple—just a few concentric circles and a toothpick drag.
Whether you're hosting a Halloween party or just want a festive treat for your family, these brownies are sure to be a hit. They're best served slightly warm with a scoop of vanilla ice cream, but they're equally delicious at room temperature. Let's get baking!
Why You'll Love This Recipe
About the Ingredients
1 cup (2 sticks / 226g) unsalted butter, melted
Use high-quality butter for the best flavor. You can substitute with salted butter but reduce the added salt to 1/4 teaspoon.
2 cups (400g) granulated sugar
Regular white sugar works best. For a deeper flavor, you can use brown sugar, but the texture will be slightly chewier.
4 large eggs, at room temperature
Room-temperature eggs incorporate better into the batter. If you're in a hurry, place them in warm water for 5 minutes.
1 cup (120g) all-purpose flour
Spoon and level the flour to avoid dense brownies. You can use gluten-free all-purpose flour for a GF version.
3/4 cup (75g) unsweetened cocoa powder
Dutch-processed cocoa gives a richer flavor, but natural cocoa works too. For a Nutella boost, you can replace 2 tablespoons with Nutella.
1/2 teaspoon salt
Fine sea salt is best. If using salted butter, omit this.
1 cup (300g) Nutella, divided
Use the classic hazelnut spread. You can substitute with any chocolate-hazelnut spread, but the flavor will vary slightly.
1/2 cup (120ml) heavy cream, for the web topping
Heavy cream (or whipping cream) is needed to thin the Nutella for piping. You can use milk, but the web will be less defined.
Tips & Tricks
Don't overmix the batter
Stir until just combined to keep the brownies fudgy, not cakey.
Use a toothpick to drag the web
Insert it deep enough to pull through the Nutella circles, but not so deep that you scrape the brownie surface.
Line your pan with parchment paper
This makes lifting the brownies out a breeze and keeps the web intact.
- Let the brownies cool completely before slicing: This ensures clean edges and prevents the web from smudging.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prep
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving overhang on two sides for easy lifting.
2. Mix Wet Ingredients
In a large bowl, whisk the melted butter and sugar until well combined. Add the eggs one at a time, whisking after each addition until the batter is glossy.
3. Add Dry Ingredients
Sift in the flour, cocoa powder, and salt. Gently fold with a spatula until just combined—do not overmix. Stir in 1/2 cup of Nutella until fully incorporated.
4. Bake the Brownies
Pour the batter into the prepared pan and spread evenly. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. The edges will be set and the top will look slightly cracked.
5. Cool Slightly
Let the brownies cool in the pan on a wire rack for 10 minutes. Then, while still warm, prepare the web topping.
6. Make the Web Mixture
In a small bowl, combine the remaining 1/2 cup Nutella with the heavy cream. Microwave in 15-second intervals, stirring until smooth and pourable.
7. Pipe the Web
Transfer the Nutella mixture to a piping bag or zip-top bag with a tiny corner cut. Pipe a spiral starting from the center of the brownies, working outward with about 1-inch gaps. Then, use a toothpick to drag lines from the center to the edges, creating a web pattern.
8. Set and Serve
Allow the web to set for at least 30 minutes before slicing. Cut into squares and serve. The brownies are best enjoyed within 2 days.
Delicious Variations
Peanut Butter Web
Replace the Nutella web with melted peanut butter mixed with a little cream.
Orange Creamsicle Twist
Add 1 teaspoon orange zest to the brownie batter and use white chocolate for the web.
Spicy Mexican Style
Add 1/2 teaspoon cinnamon and a pinch of cayenne to the dry ingredients for a kick.
How to Store Nutella Halloween Spiderweb Brownies
Refrigerator
Store in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. Bring to room temperature before serving.
Freezer
Wrap the brownies tightly in plastic wrap and freeze for up to 3 months. Thaw overnight in the refrigerator before serving.
Reheating
To reheat, microwave individual brownies for 10-15 seconds until warm, or warm in a 300°F (150°C) oven for 5 minutes.
Frequently Asked Questions
Q: Can I use a brownie mix instead of making from scratch?
Yes, you can use a 9×13-inch boxed brownie mix. Prepare the mix according to package directions, then swirl in the Nutella and bake as instructed. Just ensure the brownies are fully baked before adding the web.
Q: How do I get the spiderweb to look neat?
The key is to pipe the spiral evenly and drag the toothpick from the center outward in straight lines. Work quickly while the Nutella is still warm and pourable.
Q: Can I make these brownies gluten-free?
Absolutely! Substitute the all-purpose flour with a 1:1 gluten-free baking flour. The texture will be slightly different but still delicious.
Q: Do I have to use heavy cream for the web?
No, you can use milk or even water, but heavy cream gives a smoother, more stable web. If using milk, add it slowly to avoid making the mixture too thin.
