For the Brownies
- 1 cup butter
- ¾ cup cocoa powder
- 4 large eggs
- 2 cups sugar

- 1 teaspoon baking powder

How to Make Spider Web Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F. 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, melt the butter over low heat. Once fully melted, remove from heat and stir in the cocoa powder until well combined. Set 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 in the melted butter/cocoa mixture along with the vanilla extract. Stir until smooth.
Step 4: Combine Dry Ingredients
In another medium bowl, mix together the flour, baking powder, and salt. Gradually add this dry mixture to the wet ingredients, stirring until just combined. Pour the brownie batter into your prepared pan.
Step 5: Bake
Bake in your preheated oven for 25-30 minutes. To check if they are done, insert a toothpick into the center; it should come out clean. Allow brownies to cool completely before cutting them into squares.
Step 6: Decorate with Spider Webs
For decorative spider webs, fill a small ziplock bag with melted white chocolate. Cut off one corner of the bag and pipe chocolate onto the cooled brownies in the shape of spider webs. Serve immediately or store in an airtight container for up to 3-5 days.

How to Perfect Spider Web Brownies
For the best results in making your Spider Web Brownies, follow these helpful tips that will ensure they turn out perfectly every time.
- Use quality cocoa powder: A good quality cocoa powder enhances the flavor of the brownies, making them richer and more chocolatey.
- Don’t overmix: Mix just until ingredients are combined; overmixing can lead to dense brownies rather than light and chewy ones.
- Check for doneness: Use a toothpick to test if the brownies are done; it should come out with a few moist crumbs but not wet batter.
- Let them cool completely: Allow the brownies to cool fully before cutting. This helps maintain their shape and makes for cleaner edges.
- Experiment with toppings: Feel free to add nuts, sprinkles, or even edible glitter on top for an extra festive look!

Common Mistakes to Avoid
Creating the perfect Spider Web Brownies can be tricky, especially for Halloween. Here are some common pitfalls to steer clear of:
-
Not measuring ingredients accurately – Precision is key in baking. Use proper measuring cups and spoons to ensure your brownies turn out perfectly chewy.
-
Skipping the cooling time – Allowing the brownies to cool completely helps them set and makes cutting easier. Rushing this step can lead to messy squares.
-
Overmixing the batter – Mixing too much can make your brownies tough instead of soft and chewy. Stir until just combined for the best texture.
-
Ignoring oven temperature – Every oven is different. Use an oven thermometer if necessary to ensure your brownies bake at the right temperature for even cooking.
-
Forgetting the decorative touch – The spider web design adds a fun Halloween flair. Don’t skip this step; it’s what makes your brownies festive!
