Ingredients

Scale
  • 1 cup (2 sticks or 227g) unsalted butter, melted
  • 8 ounces (225g) semi-sweet chocolate chips
  • 1 ½ cups (300g) granulated sugar
  • 3 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup (125g) all-purpose flour (or almond flour for gluten-free)
  • ¾ cup (75g) unsweetened cocoa powder (preferably Dutch-processed)
  • ¼ teaspoon salt
  • 1 cup (120g) powdered sugar (for spider web icing)
  • 23 tablespoons (30-45ml) milk (use dairy-free milk if needed)
  • Black food coloring or edible gel (optional, for spider web detailing)

Instructions

  1. Preheat your oven to 350°F (175°C) and prepare a 9×9 inch baking pan by greasing it lightly or lining it with parchment paper.
  2. Melt the butter and chocolate chips together in a microwave-safe bowl in 30-second bursts, stirring in between until smooth, or use a double boiler on the stove.
  3. Whisk the granulated sugar into the melted chocolate mixture while it’s still warm, then add the eggs one at a time, whisking well after each addition until the batter is glossy and thick.
  4. Stir in the vanilla extract.
  5. In a separate bowl, sift together the flour, cocoa powder, and salt.
  6. Gently fold the dry ingredients into the wet chocolate batter using a rubber spatula, being careful not to over-mix; a few streaks of flour are okay.
  7. Pour the batter into the prepared pan and spread evenly. Tap the pan lightly on the counter to release air bubbles.
  8. Bake for 25-30 minutes. Check at 25 minutes by inserting a toothpick in the center; it should come out with a few moist crumbs but not wet batter.
  9. Cool the brownies completely on a wire rack before decorating.
  10. Prepare the spider web icing by mixing powdered sugar with milk, starting with 2 tablespoons and adding more as needed to get a thick but pipeable consistency.
  11. Transfer icing to a piping bag or resealable plastic bag and pipe concentric circles on the brownie surface.
  12. Use a toothpick or skewer to drag lines from the center outward to create the spider web effect.
  13. Let the icing set for at least 20 minutes before slicing and serving.

Notes

Do not overbake the brownies to keep them fudgy. Use room temperature eggs for smooth batter. Melt chocolate and butter slowly to avoid burning. Pipe spider web icing carefully for best results. Icing can be prepared a day ahead and stored in the fridge.
