Ingredients
To make 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 Frosting 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 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 over low heat, melt the butter. Once melted, remove from heat and stir in the cocoa powder until combined. Set aside to cool slightly.
Step 3: Mix Wet Ingredients
In a large mixing bowl, beat together 4 large eggs, 2 cups sugar, and 3 tablespoons vegetable oil. Mix until the mixture is light and foamy. Then add the butter/cocoa mixture along with 2 teaspoons vanilla extract. Stir until smooth.
Step 4: Combine Dry Ingredients
In another medium bowl, whisk together 1 ½ cups all-purpose flour, 1 teaspoon baking powder, and 1 teaspoon salt. Gradually add this dry mixture into your wet ingredients. Stir until just combined.
Step 5: Bake Your Brownies
Pour the brownie batter into your prepared pan. Bake in the 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 to cool completely before cutting into squares.
Step 6: Add Decorative Frosting
For the spider web decoration, 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.
