Step-by-Step Instructions
- Preheat your oven to 350°F (180°C) and line a 9x13x2 inch baking pan with parchment paper, lightly greasing it.
- In a medium-sized bowl, whisk together the flour, baking soda, and kosher salt.
- In a large mixing bowl, beat together butter, dark brown sugar, and granulated sugar until creamy. Add eggs and vanilla extract, mixing well.
- Gradually add the dry flour mixture to the wet ingredients, mixing until just combined. Fold in Reese's Pieces and chocolate M&M's.
- Spread the dough evenly into the prepared baking pan and bake for 18-20 minutes.
- Immediately press the chopped leftover Halloween candies and candy eyes into the surface of the warm cookie bars.
- Allow to cool completely in the pan for 30-45 minutes, then slice into squares.
