Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour
  • ½ cup (50g) black cocoa powder (Hershey’s Special Dark recommended)
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1 cup (226g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon pure vanilla extract
  • 2 tablespoons (30ml) milk, optional (if dough feels too stiff)
  • 2 cups (240g) powdered sugar (for icing)
  • 23 tablespoons (30-45ml) milk (for icing)
  • 1 tablespoon light corn syrup (can substitute with honey, for icing)
  • ½ teaspoon vanilla extract (for icing)
  • Black food coloring gel, a small amount (for icing)

Instructions

  1. In a medium bowl, sift together 2 ½ cups all-purpose flour, ½ cup black cocoa powder, 1 teaspoon baking powder, and ½ teaspoon salt. Set aside.
  2. In a large bowl, beat 1 cup softened unsalted butter and 1 cup granulated sugar with an electric mixer until light and fluffy, about 3-4 minutes.
  3. Beat in 1 large egg and 1 teaspoon vanilla extract until fully combined.
  4. Gradually add the dry ingredients to the wet mixture, mixing on low speed. If dough feels too stiff or crumbly, add 1-2 tablespoons milk to bring it together. Dough should be soft but not sticky.
  5. Wrap dough in plastic wrap and refrigerate for at least 1 hour.
  6. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats.
  7. Lightly flour work surface and roll chilled dough to about ¼ inch (6mm) thickness. Use cookie cutters to cut shapes, placing them at least 1 inch apart on baking sheets.
  8. Bake cookies for 10-12 minutes until set but still soft in the center. Avoid overbaking.
  9. Transfer cookies to wire racks to cool completely before icing.
  10. For icing, whisk 2 cups powdered sugar with 2 tablespoons milk, 1 tablespoon light corn syrup, and ½ teaspoon vanilla extract until smooth. Add black gel food coloring drop by drop until deep black.
  11. Spread a thin, even layer of black icing on each cookie using a piping bag or spoon. Let set about 10 minutes.
  12. Pipe concentric circles of white or contrasting icing over black base. Drag a toothpick from center outward through circles to create spider web effect. Work quickly before icing sets.
  13. Allow decorated cookies to rest at room temperature for at least 30 minutes before serving or storing.

Notes

Sift black cocoa powder to avoid clumps. Chill dough for at least 1 hour for easier rolling and less spreading. Keep icing consistency thick but spreadable for best spider web effect. Work quickly when creating spider web design. Dough can be chilled up to 24 hours before baking. For dairy-free option, substitute butter with coconut oil and use almond milk for icing. Dutch-processed cocoa powder can substitute black cocoa but will yield lighter color and flavor.
