Ingredients

Scale
  • 1/2 cup (113 g) unsalted butter, melted
  • 1 cup (200 g) granulated sugar
  • 2 large eggs, room temperature
  • 1 tsp pure vanilla extract
  • 3/4 cup (95 g) all-purpose flour, sifted
  • 1/2 cup (50 g) unsweetened cocoa powder, preferably Dutch-processed
  • 1/4 tsp salt
  • 1 cup (175 g) white chocolate chips or chunks, good quality
  • 2 tbsp (30 ml) heavy cream
  • Optional: black food gel or melted dark chocolate for spider accents

Instructions

  1. Preheat oven to 350°F (175°C). Line an 8×8 inch pan with parchment paper, leaving an overhang for easy removal.
  2. In a medium bowl, whisk melted butter and granulated sugar until combined and glossy. Add eggs one at a time, whisking well after each addition. Stir in vanilla extract.
  3. In a separate bowl, sift together flour, cocoa powder, and salt.
  4. Gently fold dry ingredients into wet mixture using a rubber spatula until just combined and smooth. Do not overmix.
  5. Pour batter into prepared pan and spread evenly. Tap pan lightly to remove air bubbles.
  6. Bake for 20-25 minutes. Check at 20 minutes with a toothpick; it should come out with a few moist crumbs but no wet batter.
  7. Cool brownies completely in the pan on a wire rack for at least 1 hour.
  8. Melt white chocolate with heavy cream in 20-second bursts in the microwave, stirring well after each until smooth and pourable.
  9. Pour white chocolate into a piping bag or plastic bag. Pipe concentric circles starting from the center of the brownies.
  10. Use a toothpick to drag lines from the center to the edges to create a spider web pattern.
  11. Optional: Add small spider shapes using black food gel or melted dark chocolate.
  12. Let the white chocolate set at room temperature or refrigerate for about 15 minutes before slicing.
  13. For clean cuts, dip a sharp knife in hot water, wipe dry, and slice.

Notes

Melt white chocolate slowly and stir often to avoid burning. Cool brownies completely before piping the web to prevent melting. Use a sharp knife dipped in hot water for clean cuts. Practice piping on parchment paper if needed.
