Description

These Spooky Spider Brownies are the perfect Halloween dessert—rich, fudgy brownies decorated with candy eyes and chocolate legs. Fun, easy, and kid-friendly, they’re ideal for parties, bake sales, or family nights.


Ingredients

Scale

For the brownies:

  • 1 cup 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 decorations:

  • Candy eyes

  • Pretzel sticks or licorice strings (for legs)

  • Melted chocolate or black icing (for attaching)

  • Optional: sprinkles or edible glitter


Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan.
  2. Whisk melted butter and sugar until smooth. Add eggs one at a time, then stir in vanilla.
  3. In a separate bowl, sift flour, cocoa powder, baking powder, and salt. Gently fold into the wet mixture.
  4. Spread batter evenly in pan and bake 25–30 minutes, until a toothpick comes out with moist crumbs.
  5. Cool completely before cutting into squares.
  6. Decorate each brownie with two candy eyes and pretzel/licorice legs, using melted chocolate to secure.
  7. Add sprinkles or edible glitter for extra spooky fun.

Notes

  • For fudgier brownies, slightly underbake and cool fully before slicing.
  • Make ahead: bake brownies a day in advance and decorate before serving.
  • Store in an airtight container for up to 3 days, or freeze undecorated brownies for a month.
