Ingredients

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 Decoration

How to Make Spider Web Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line your 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 melted, remove from heat and stir in the cocoa powder until fully combined. Set aside.
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 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 mixture to the wet ingredients, stirring until just combined.
Step 5: Bake the Brownies
Pour the brownie batter into your prepared pan. Bake in the preheated oven for 25-30 minutes. A toothpick inserted into the center should come out clean. Allow them to cool completely before cutting into squares.
Step 6: Create Decorative Spider Webs
For decorating, fill a small ziplock bag with melted white chocolate. Cut off one corner of the bag and pipe chocolate frosting onto each brownie in a spider web pattern. Serve immediately or store in an airtight container for up to 3-5 days.

How to Perfect Spider Web Brownies
To ensure your Spider Web Brownies turn out perfectly every time, follow these helpful tips.
- Use Fresh Ingredients: Ensure your eggs and butter are fresh for the best flavor and texture.
- Do Not Overmix: Mix your batter just until combined to keep the brownies chewy rather than cakey.

- Experiment with Toppings: Try adding nuts or different types of chocolate chips for added flavor and texture variations.

Common Mistakes to Avoid
Making Spider Web Brownies can be simple, but a few common mistakes can lead to less-than-perfect results. Here are some pitfalls to watch out for:
-
Skipping the cooling time: Allowing the brownies to cool completely before cutting is essential. If you cut them too soon, they may fall apart.
-
Using cold ingredients: Ensure that your eggs and butter are at room temperature. Cold ingredients can prevent the batter from mixing properly, leading to uneven texture.
-
Overmixing the batter: Mix just until combined. Overmixing can result in tough brownies instead of the desired chewy texture.
-
Not measuring ingredients accurately: Baking requires precision. Use a kitchen scale or measuring cups accurately to ensure the right balance of flavors and textures.
-
Ignoring baking time: Every oven is different. Start checking your brownies a few minutes before the suggested baking time to avoid overbaking.
