- Small ziplock bag (for piping)

Ingredients
To create these delightful Spider Web Brownies, you’ll need the following 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
- ⅓ cup white chocolate chips (melted)
How to Make Spider Web Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line your 9×13 inch baking pan with foil and spray it lightly with cooking spray to prevent sticking.
Step 2: Melt the Butter
In a medium saucepan, melt the butter over low heat. Once completely melted, remove it from the heat and stir in the cocoa powder until well blended. Set aside to cool slightly.
Step 3: Mix Wet Ingredients
In a large mixing bowl, beat together four large eggs, two cups of sugar, and three tablespoons of vegetable oil until the mixture is light and foamy. Add the melted butter-cocoa mixture along with two teaspoons of vanilla extract. Stir everything together until smooth.
Step 4: Combine Dry Ingredients
In another medium bowl, mix together one and a half cups of all-purpose flour, one teaspoon of baking powder, and one teaspoon of salt. Gradually add this dry mixture to your wet ingredients while stirring until just combined.
Step 5: Bake
Pour the brownie batter into your prepared pan. Bake in your preheated oven for 25-30 minutes. Check doneness by inserting a toothpick into the center; it should come out clean. Once done, allow them to cool completely before cutting into squares.
Step 6: Decorate with Spider Webs
To create the spooky spider web decoration, fill a small ziplock bag with melted white chocolate. Cut off one corner of the bag and pipe the melted chocolate onto each brownie in a spider web pattern. Serve immediately or store in an airtight container for up to 3-5 days.
