Spiderweb Brownies

What I love about these spooky Halloween brownies is how approachable they are. You don’t need professional decorating skills or fancy tools—just a steady hand and a toothpick will do the trick.

Equipment

  • 9x13-inch Baking Pan
  • Mixing Bowls
  • Whisk & spatula
  • Toothpick or Skewer
  • Microwave-safe bowl or double boiler
  • Sharp Knife

Ingredients
  

For the Brownies:

  • 1 cup 2 sticks unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1 cup unsweetened cocoa powder
  • ½ teaspoon baking powder
  • ½ teaspoon salt

For the Spiderweb Topping:

  • ½ cup white chocolate chips or white candy melts
  • 1 teaspoon coconut oil optional, for smoother melting

Instructions
 

Step 1: Prep Your Pan and Oven

  • Preheat your oven to 350°F (175°C).
  • Lightly grease a 9x13-inch baking pan or line it with parchment paper (leave some overhang for easy lifting later).
  • Set aside while you make the batter.
  • Pro Tip: Lining with parchment makes removing and slicing the brownies a breeze—no sticking, no crumbling edges.

Step 2: Mix the Wet Ingredients

  • In a large mixing bowl, whisk together the melted butter and sugar until combined and glossy.
  • Add in the eggs one at a time, whisking well after each addition.
  • Stir in the vanilla extract until smooth.
  • Pro Tip: Whisk continuously to help dissolve the sugar—it gives you that shiny, crackly top on the brownies.

Step 3: Combine the Dry Ingredients

  • In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt.
  • Slowly add the dry mixture into the wet mixture.
  • Switch to a spatula and gently fold until just combined—no flour streaks should remain.
  • Pro Tip: Don’t overmix at this stage. Overmixing can make brownies dense instead of fudgy.

Step 4: Bake the Brownies

  • Pour the batter evenly into your prepared pan.
  • Smooth out the top with a spatula so it bakes evenly.
  • Bake for 28–32 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).
  • Pro Tip: Every oven runs differently—start checking at 28 minutes to avoid overbaking.

Step 5: Make the Spiderweb Topping

  • In a microwave-safe bowl, melt the white chocolate chips with the coconut oil in 20-second intervals, stirring after each until smooth.
  • Transfer the melted chocolate into a piping bag (or a small zip-top bag with the corner snipped off).
  • Pro Tip: If the chocolate feels too thick, stir in a tiny extra splash of coconut oil to loosen it up.

Step 6: Create the Spiderweb Design

  • While the brownies are still slightly warm (but not hot), drizzle the melted white chocolate in concentric circles on top of the brownies.
  • Take a toothpick or skewer and drag lines outward from the center to the edges, creating a web effect.
  • Let the brownies cool completely so the chocolate sets before slicing.
  • Pro Tip: Wipe your toothpick clean between each drag for sharper, more defined web lines.
