Why I Can’t Stop Making These Cookies

• Quick Win: They come together in less than 45 minutes, from batter to spiderweb decoration.
• Flavor Twist: The combination of dark cocoa with creamy white chocolate makes these brownies stand out.
• Pantry-Friendly: You likely have most of the ingredients on hand—perfect for last-minute treats.
• Kid-Friendly: Little hands love helping with the spiderweb design, making this a fun activity too.
• Seasonal Appeal: These brownies evoke a spooky vibe without being overly scary, making them suitable for all ages.

What Type of Chocolate Should I Use?

For the best brownies, choose unsweetened cocoa powder with a deep, rich flavor. Dutch-processed cocoa produces a smoother taste, while natural cocoa has a more intense chocolate flavor. Use good-quality semi-sweet or bittersweet chocolate chips or bars for melting into the batter.

White chocolate for the spiderweb design should be smooth and creamy. Real white chocolate melts more evenly than white confectionery wafers, but if you use wafers, be sure to watch them closely to avoid burning.

Options for Ingredient Alternatives

• Swap butter for oil (like vegetable or canola) for a moister brownie with a slightly different texture.
• Use dark chocolate or milk chocolate chips if you prefer sweeter or milkier brownies.
• Replace dairy milk with almond, oat, or coconut milk if needed.
• Try vanilla extract or orange extract to experiment with subtle flavor changes—orange adds a great Halloween vibe.
• For the spiderweb, you can use white chocolate chips or white candy melts. If you’re using coconut oil instead of butter, be sure to chill the batter before baking.

The Biggest Challenges While Baking

• Folding the white chocolate last and gently helps keep your spiderweb design smooth and flawless.
• Ensure your butter is softened but not melted to maintain the correct batter texture.
• Avoid overmixing the batter to keep brownies fudgy, not cakey.
• If the brownie dough feels dry, add milk one tablespoon at a time until it’s moist but not runny.
• Chilling the batter for 30 minutes before baking helps deepen the flavors and keeps the edges less crumbly.

Storage & Freezing Instructions

Store cooled brownies in an airtight container at room temperature for up to 3 days. For longer freshness, keep them in the refrigerator up to 1 week. You can freeze brownies wrapped tightly in plastic wrap and foil for up to 3 months. Thaw at room temperature before serving. To freeze unbaked dough, press it into the pan, cover tightly, and freeze; thaw in the fridge overnight before baking.

Ingredients

• 1 cup granulated sugar (200 g)
• 1/2 cup unsalted butter, softened (115 g)
• 2 large eggs
• 1 tsp vanilla extract
• 1/3 cup unsweetened cocoa powder (35 g)
• 1/2 cup all-purpose flour (60 g)
• 1/4 tsp salt
• 1/4 tsp baking powder
• 1/2 cup semi-sweet chocolate chips (85 g), divided
• 1/2 cup white chocolate chips (85 g), for spiderweb decoration
• Optional: 1-2 Tbsp milk, only if batter is too thick (15-30 ml)

Step-by-Step Instructions

1. Preheat your oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper, leaving a bit of overhang for easy removal.
2. In a microwave-safe bowl, melt 1/4 cup of the semi-sweet chocolate chips with the butter in 30-second intervals, stirring between each interval until smooth. Let it cool slightly.
3. In a mixing bowl, whisk together sugar, eggs, and vanilla until smooth and glossy.
4. Slowly add the melted chocolate mixture to the egg mixture, stirring gently to combine.
5. Sift together cocoa powder, flour, salt, and baking powder, then fold into the wet ingredients until just combined. Add the remaining 1/4 cup of chocolate chips and mix gently. If the batter feels too thick, stir in 1 tablespoon of milk at a time.
6. Pour the batter into the prepared pan, smoothing the top with a spatula. Bake for 20-25 minutes or until a toothpick comes out with a few moist crumbs but not wet batter.
7. While the brownies cool slightly, melt the white chocolate chips in short bursts in the microwave, stirring until smooth. Transfer the melted white chocolate to a small piping bag or a zip-top bag with a tiny corner snipped off. Pipe concentric circles over the brownies. Use a toothpick or skewer to drag lines from the center outward, creating a spiderweb pattern. Let set completely before slicing.

Tips, Variations & Serving Ideas

• Sprinkle a pinch of sea salt on top before baking to enhance the chocolate flavor.
• Add chopped nuts, such as pecans or walnuts, to the batter for added crunch.
• Use orange or purple candy melts for a colorful spiderweb variation.
• Underbake by a couple of minutes for fudgier centers.
• Serve with a scoop of vanilla ice cream for an extra treat.
• Store in a cool place for a day to let the flavors mellow before serving.
• Make mini spiderweb brownies by using a muffin tin to bake.
