Method
 

Step-by-Step Instructions
  1. Preheat your oven to 350°F (175°C) and prepare an 8x8-inch baking pan by lining it with parchment paper.
  2. In a large mixing bowl, cream together the softened unsalted butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes. Incorporate the egg and vanilla extract until well combined.
  3. Gradually add the all-purpose flour, baking soda, and salt to the wet mixture. Stir gently until just incorporated.
  4. Fold in the chocolate chips and Halloween M&Ms, reserving some for topping.
  5. Transfer the dough into the prepared baking pan, spreading evenly. Press reserved candies and candy eyeballs into the top.
  6. Bake for about 20-25 minutes until golden brown around the edges but soft in the center. Let cool completely in the pan before cutting.
