Ingredients

Scale

Dough

  • 1/2 cup unsalted butter, softened
  • 1/2 cup brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 1 1/4 cups all-purpose flour
  • 1/2 tsp baking soda
  • 1/4 tsp salt

Mix-ins and Toppings

  • 1/2 cup chocolate chips
  • 1/2 cup Halloween M&Ms or candy-coated chocolates
  • 1/4 cup candy eyeballs
  • Optional: sprinkles or chopped candy bars

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper to prevent sticking and ensure easy removal of the cookie bars.
  2. Cream Butter and Sugars: In a large mixing bowl, beat the softened unsalted butter with the brown sugar and granulated sugar until the mixture becomes light and fluffy, indicating that air has been incorporated.
  3. Add Egg and Vanilla: Mix in the egg and vanilla extract until the batter is smooth and well combined, which helps to create a cohesive dough.
  4. Combine Dry Ingredients: Stir in the all-purpose flour, baking soda, and salt just until all the dry ingredients are incorporated, being careful not to overmix to maintain a tender texture.
  5. Fold in Chocolate Chips and M&Ms: Gently fold in the chocolate chips and Halloween M&Ms, saving a few pieces to press on top of the dough for decoration.
  6. Spread Dough in Pan: Evenly spread the dough into the prepared baking pan, then press the reserved candies and candy eyeballs firmly onto the top so they stick during baking.
  7. Bake: Place the pan in the oven and bake for 20 to 25 minutes, or until the edges turn golden brown and the center is set but still slightly soft.
  8. Cool and Serve: Allow the cookie bars to cool completely in the pan on a wire rack before lifting them out and cutting into squares to serve.

Notes

  • Make sure the butter is softened but not melted for best creaming results.
  • Do not overmix the dough once the flour is added to keep the bars tender.
  • Use an 8×8 inch pan for the best thickness and texture.
  • Cooling completely before cutting helps the bars hold their shape.
  • Feel free to customize with your favorite Halloween candies or sprinkles.
