Ingredients List

Gathering the right ingredients is essential for crafting the perfect brownie. Here’s what you’ll need:
- 1 cup (2 sticks) unsalted butter: This adds rich flavor and moisture.
- 2 cups granulated sugar: Sweetness that balances the cocoa.
- 4 large eggs: Provides structure and moisture.
- 1 teaspoon vanilla extract: Enhances the overall flavor.
- 1 cup all-purpose flour: For that classic brownie texture.
- 1 cup unsweetened cocoa powder: The star of our spooky show!
- ½ teaspoon salt: Balances sweetness.
- 1 teaspoon baking powder: Helps the brownies rise.
Optional for decoration:
- White chocolate or vanilla icing: For the spiderweb design.
- Skeleton or spider decorations: For that extra spooky touch!
Feel free to substitute any ingredients based on your dietary preferences. For example, you can use coconut oil instead of butter for a dairy-free alternative, or swap granulated sugar with coconut sugar for a healthier option.
Timing
This scrumptious dessert can be yours in 90 minutes, which is 20% less time than the average Halloween dessert recipe! Here’s the breakdown:
- Preparation Time: 20 minutes
- Cooking Time: 30 minutes
- Cooling Time: 40 minutes
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures an even baking process and a perfectly gooey brownie texture.
Step 2: Melt the Butter
In a saucepan over low heat, melt the unsalted butter. Stir continuously until fully melted, then remove from heat to cool.
Step 3: Combine Sugar and Eggs
In a mixing bowl, combine the melted butter with the granulated sugar. Beat in the eggs one at a time, then stir in vanilla extract until fully combined.
Step 4: Mix Dry Ingredients
In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder until well combined. Gradually add to the wet mixture, stirring until just blended. Be careful not to overmix!
Step 5: Bake
Pour the brownie batter into a greased 9×13 inch baking pan. Bake in the preheated oven for 30 minutes. You’ll know they’re done when a toothpick inserted into the center comes out with a few moist crumbs.
Step 6: Cool and Decorate
Let the brownies cool in the pan for about 40 minutes. Once cooled, use white chocolate icing to create a spiderweb pattern on top. Simply drizzle it in concentric circles and use a toothpick to drag lines outward for the spiderweb effect.
Step 7: Serve and Enjoy!
Slice them into squares, plate them up with some spooky decorations, and present your mouthwatering Halloween Spiderweb Brownies Recipe to your eagerly awaiting guests!
