For the Brownies
- 1 cup butter
- ¾ cup cocoa powder
- 4 large eggs
- 2 cups sugar
- 3 tablespoons vegetable oil
- 2 teaspoons vanilla extract
- 1 ½ cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon salt
For the Spiderweb Decoration

How to Make Spider Web Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a 9×13 inch pan with foil and spray it with cooking spray to prevent sticking.
Step 2: Melt the Butter
In a medium saucepan over low heat, melt the butter. Once fully melted, remove it from heat. Stir in the cocoa powder until well combined. Set this mixture aside to cool slightly.
Step 3: Mix Wet Ingredients
In a large bowl, beat together the eggs, sugar, and vegetable oil until light and foamy. Add the cooled butter/cocoa mixture along with the vanilla extract. Stir until smooth and combined.
Step 4: Combine Dry Ingredients
In another medium bowl, mix together the flour, baking powder, and salt. Gradually add this dry mixture to your wet ingredients while stirring until everything is well combined.
Step 5: Bake the Brownies
Pour the brownie batter into your prepared pan. Bake for approximately 25-30 minutes. To check if they’re done, insert a toothpick into the center; it should come out clean. Allow cooling completely before cutting into squares.
Step 6: Create Spiderweb Design
For decorating, fill a small ziplock bag with melted white chocolate. Snip off one corner of the bag and pipe chocolate onto the brownies in the shape of spider webs. Serve immediately or store in an airtight container for up to 3-5 days.
How to Serve Spider Web Brownies
Serving Spider Web Brownies can turn any gathering into a festive occasion, especially during Halloween. Here are some creative ways to present these delicious treats.
Individual Brownie Cups

Spider-Themed Platter
- Arrange brownies on a platter with toy spiders or Halloween decorations for a spooky display that enhances the festive atmosphere.
Ice Cream Sundae Style
- Top warm brownie squares with vanilla ice cream and drizzle with chocolate syrup for a delightful dessert experience that combines flavors and textures.
Brownie Sandwiches

Pair with Hot Beverages

How to Perfect Spider Web Brownies
To ensure your Spider Web Brownies turn out perfectly every time, keep these tips in mind.
-
Use quality cocoa powder: Opt for high-quality cocoa powder for richer flavor in your brownies.
-
Don’t overmix the batter: Mix just until combined; overmixing can lead to tough brownies.
-
Check baking time carefully: Start checking at 25 minutes to avoid overbaking and keep them chewy.
-
Cool completely before cutting: Allowing brownies to cool ensures cleaner cuts and better texture.
-
Experiment with toppings: Try adding nuts or caramel swirls before baking for added flavor and texture.
Best Side Dishes for Spider Web Brownies
Pairing your Spider Web Brownies with complementary side dishes can elevate your dessert experience. Here are some great options:
-
Pumpkin Spice Whipped Cream: A seasonal favorite, this cream adds a flavorful twist that pairs well with chocolate.
-
Caramel Sauce: Drizzle warm caramel over the brownies or serve on the side for an extra indulgent touch.
-
Chocolate Chip Cookies: Offering classic cookies alongside your brownies creates a delightful dessert duo.
-
Fruit Salad: A refreshing fruit salad balances the rich flavors of the brownies, adding color and nutrition.
-
Cheesecake Bites: Mini cheesecake bites provide a creamy counterpart to the fudgy texture of brownies.
-
Coffee or Espresso: Serving coffee enhances the chocolate flavor, creating a perfect pairing for dessert lovers.
-
Milkshakes: Chocolate or vanilla milkshakes add a fun, nostalgic touch that complements the sweetness of brownies.
Common Mistakes to Avoid
Making Spider Web Brownies can be fun, but there are common pitfalls that can lead to disappointing results.
-
Skipping the Cooling Time: Allowing the brownies to cool completely before cutting helps maintain their shape and texture. Cutting them too early may result in a messy, crumbly mess.
-
Overmixing the Batter: Mixing the batter too much can create dense brownies. Stir just until the ingredients are combined for a light and chewy texture.
-
Incorrect Oven Temperature: Oven temperatures can vary, so it’s essential to use an oven thermometer. Baking at the wrong temperature can lead to undercooked or burnt brownies.
-
Not Measuring Flour Correctly: Spoon and level your flour rather than scooping it directly from the bag. This avoids adding too much flour, which can make your brownies dry.
-
Ignoring Frosting Tips: When decorating with melted white chocolate, use a piping bag or ziplock for precision. Not doing this can result in messy spider webs that don’t look appealing.
