Ingredients

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

- 2 teaspoons vanilla extract
- 1 ½ cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon salt
For the Decorative Spiderwebs
- 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 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 it’s fully melted, remove it from the heat and stir in the cocoa powder until combined. Set this mixture aside to cool slightly.
Step 3: Prepare the Wet Ingredients
In a large mixing bowl, beat together the eggs, sugar, and vegetable oil until light and foamy. Add in the cooled butter-cocoa mixture along with the vanilla extract. Stir until everything is well combined and smooth.
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, stirring just until combined. Avoid overmixing!
Step 5: Bake Your Brownies
Pour the brownie batter into your prepared pan and spread it evenly. Bake in your preheated oven for about 25-30 minutes. To check if they’re done, insert a toothpick into the center; it should come out clean. Allow your brownies to cool completely before cutting them into squares.
Step 6: Create Spiderweb Decorations
For the decorative spider webs, fill a small ziplock bag with melted white chocolate. Cut off one corner of the bag to pipe chocolate frosting onto your cooled brownies in a spider web shape. Serve immediately or store in an airtight container for up to 3-5 days.

Common Mistakes to Avoid

Skipping the cooling step: Allowing the brownies to cool completely is crucial for clean cuts and better texture. Skipping this can lead to messy squares.
Not measuring ingredients accurately: Baking is a science, so using incorrect measurements can throw off the recipe. Always use measuring cups and spoons for precision.
Using cold eggs: Cold eggs can cause the batter to become lumpy. To avoid this, let your eggs come to room temperature before mixing them in.
