Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
- In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt.
- In a large mixing bowl, beat together the butter, granulated sugar, and light brown sugar until light and fluffy.
- Add the egg and vanilla extract to the butter-sugar mixture, blending until fully combined.
- Gradually add the dry ingredients to the wet mixture, mixing until just combined.
- Gently stir in the chocolate chips.
- Fold in the mini marshmallows and marshmallow fluff if using.
- Using a cookie scoop, place dollops of dough onto the prepared baking sheets, leaving space between each.
- Bake for 8-10 minutes or until edges are set; cool on sheets for 5 minutes before transferring to a wire rack.

Notes
Store cookies in an airtight container at room temperature for up to 5 days; adding a slice of bread keeps them soft.
