Ingredients

Scale

Main Ingredients

  • 1 cup smooth or crunchy peanut butter
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar, packed
  • 1/2 cup unsalted butter, softened
  • 2 large eggs
  • 1 1/4 cups all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla extract

Decorative Toppings

  • Candy eyeballs
  • Halloween-themed sprinkles (black, orange)
  • Melted chocolate for drizzling
  • Candy spiders, edible glitter, white icing webs (optional)

Instructions

  1. Preheat and Prepare Your Pan: Start by preheating your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper or lightly grease it to ensure your bars come out easily without sticking.
  2. Cream the Butter and Sugars: In a large mixing bowl, combine softened butter with granulated and brown sugars. Beat together until the mixture is light and fluffy, creating a smooth base for the cookie bars.
  3. Add Peanut Butter and Eggs: Mix in your peanut butter until fully incorporated. Then add eggs one at a time, beating well after each addition to build the creamy texture and rich flavor foundation.
  4. Incorporate Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and a pinch of salt. Gradually add this dry mixture to the wet ingredients, stirring gently until just combined—avoid overmixing to keep the bars tender.
  5. Spread and Decorate: Transfer the dough evenly into your prepared pan, smoothing the top with a spatula. Decorate with candy eyeballs, sprinkles, or drizzle with melted chocolate to achieve a spooky Halloween look. Gently press decorations onto the dough to help them stick.
  6. Bake and Cool: Bake for 25-30 minutes, or until edges are golden and a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Let the bars cool completely before slicing for clean squares that hold their shape.

Notes

  • Use room temperature softened butter and eggs for smooth mixing and even baking.
  • Stir just until combined to avoid toughness and keep the bars soft.
  • Rotate your pan halfway through baking for uniform color and doneness.
  • Decorate the bars before baking to help toppings adhere well.
  • Cut bars with a warm knife to achieve clean edges.
