Ingredients
  

  • Here’s everything you’ll need to make about 16 rich and spooky brownies:
Dry Ingredients
  • 1 cup all-purpose flour
  • ¾ cup Dutch-process cocoa powder
  • cups granulated sugar
  • ¼ teaspoon salt
Wet Ingredients
  • ¾ cup refined coconut oil or unsalted butter, melted
  • 3 large eggs
  • 1 tablespoon vanilla extract
Chocolate Additions
  • 1 cup semi-sweet chocolate chips for inside the brownies
  • ½ cup white chocolate chips for spiderweb topping
  • ½ cup heavy cream for melting white chocolate

Equipment

  • To craft these spooky treats, you’ll need:
  • 8x8-inch or 9x9-inch square baking pan
  • Mixing bowls (large and medium)
  • Whisk and rubber spatula
  • Sifter (for flour and cocoa powder)
  • Microwave-safe bowl (for melting chocolate)
  • Parchment paper
  • Toothpick or skewer (for spiderweb design)
  • Cooling rack

Method
 

Step 1: Preheat & Prep
  1. Preheat your oven to 350°F (175°C).
  2. Line a baking pan with parchment paper, leaving some overhang for easy removal later.
  3. Lightly grease the parchment to prevent sticking.
Step 2: Combine the Wet Ingredients
  1. In a large mixing bowl, whisk together coconut oil (or melted butter), sugar, and vanilla extract until smooth.
  2. Add the eggs one at a time, whisking well after each addition until glossy and combined.
Step 3: Add the Dry Ingredients
  1. Sift in flour, cocoa powder, and salt directly into the wet mixture.
  2. Fold gently with a spatula until just combined — don’t overmix!
  3. Stir in the semi-sweet chocolate chips for extra fudgy texture.
Step 4: Bake the Brownies
  1. Pour the batter into the prepared pan and smooth the top evenly.
  2. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs.
  3. Allow the brownies to cool completely on a rack before decorating.
Step 5: Create the Spiderweb Design
  1. In a microwave-safe bowl, combine white chocolate chips and heavy cream.
  2. Microwave in 15-second bursts, stirring between each, until smooth and glossy.
  3. Pour the melted white chocolate into a piping bag or ziplock bag with a small corner cut off.
  4. Pipe 3–4 concentric circles (like a target) on top of the cooled brownies.
  5. Using a toothpick, drag lines from the center outward to create a perfect spiderweb effect! 🕸️
Step 6: Chill & Slice
  1. Refrigerate for 15–20 minutes to set the white chocolate design.
  2. Slice into squares or rectangles and serve your spooky delights!
