Easy and festive Halloween brownies with a spooky spiderweb design.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter
  • 2 cups granulated sugar
  • 1 cup unsweetened cocoa powder
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract
  • 4 large eggs
  • 1 cup all-purpose flour
  • 1/2 cup white chocolate chips
  • 1/4 cup heavy cream
  • Black food coloring

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
  2. In a large bowl, melt the butter. Stir in the sugar and cocoa powder until well combined.
  3. Add the baking powder, salt, and vanilla extract. Mix well.
  4. Beat in the eggs one at a time until the batter is smooth.
  5. Gradually add the flour, mixing until just combined. Do not overmix.
  6. Pour the batter into the prepared baking pan and spread evenly.
  7. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
  8. Let the brownies cool completely in the pan.
  9. While the brownies cool, prepare the spiderweb topping. In a small microwave-safe bowl, combine the white chocolate chips and heavy cream. Microwave in 30-second intervals, stirring in between, until the chocolate is melted and smooth.
  10. Divide the melted white chocolate into two small bowls. Leave one bowl plain white. Add a few drops of black food coloring to the second bowl and stir until you achieve a black color.
  11. Transfer the white chocolate mixture to a piping bag or a zip-top bag with a corner snipped off. Do the same for the black chocolate mixture.
  12. Pipe concentric circles of white chocolate onto the cooled brownies.
  13. Immediately use a toothpick or skewer to drag lines from the center outwards through the white circles, creating a spiderweb pattern.
  14. Repeat this process across the entire surface of the brownies.
  15. Allow the spiderweb topping to set before cutting and serving.

Notes

  • For a richer chocolate flavor, use high-quality cocoa powder.
  • Ensure your brownies are completely cool before decorating to prevent the white chocolate from melting too quickly.
  • If you don’t have black food coloring, you can omit the black chocolate and just use white chocolate for a lighter web design.
  • Consider using a cream cheese frosting base for a different flavor profile and a more vibrant web contrast.
