Step-by-Step Instructions
- Preheat your oven to 180°C (350°F) and line two baking sheets with parchment paper.

- In a medium bowl, whisk together all-purpose flour, cocoa powder, baking soda, and salt.

- In a large mixing bowl, cream together softened unsalted butter, granulated sugar, and brown sugar until light and fluffy.

- Beat in eggs, one at a time, then mix in vanilla extract until the batter is smooth.

- Gradually mix the dry ingredients into the wet mixture until just combined.

- Fold in mini marshmallows gently, ensuring they're evenly distributed throughout the dough.

- Using a cookie scoop, portion out the dough onto the prepared baking sheets, spacing them about 2 inches apart.

- Create a gentle swirl through the dough with a toothpick, incorporating some additional marshmallows from the top.

- Bake for 10–12 minutes, ensuring the edges are set and the centers remain soft.

- Allow the cookies to cool on the baking sheets for 5 minutes before transferring to a wire rack.

Notes
For extra flavor, chill the dough for up to 24 hours before baking. Store cookies in an airtight container at room temperature for up to 5 days.
