For the Brownies

- ¾ cup cocoa powder
- 4 large eggs
- 2 cups sugar

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 Butter and Mix Cocoa
In a medium saucepan, melt the butter. Once melted, remove from heat and stir in the cocoa powder. Set aside to cool slightly.
Step 3: Beat Eggs and Combine Ingredients
In a large bowl, beat together the eggs, sugar, and vegetable oil until the mixture is light and foamy. Add the butter-cocoa mixture along with vanilla extract. Stir until smooth.
Step 4: Combine Dry Ingredients
In another medium bowl, mix together the all-purpose flour, baking powder, and salt. Gradually add this dry mixture to the wet ingredients. Stir until just combined.
Step 5: Bake the Brownies
Pour the brownie batter into your prepared pan. Bake in the preheated oven for about 25-30 minutes. A toothpick inserted into the center should come out clean. Allow cooling completely before cutting into squares.
Step 6: Decorate with Spider Webs
To create decorative spider webs, fill a small ziplock bag with melted white chocolate. Cut off one corner of the bag and pipe chocolate onto each brownie in a web pattern. Serve immediately or store in an airtight container for up to 3-5 days.
